Accounting for business combination under same control and not under same control As an acquirer, the assets and liabilities that The Group obtained in a business combination under the same control should be measured on the basis of their carrying amount in the consolidated 36 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report financial statements on the combining date. As for the balance between the carrying amount of the net assets obtained by the combining party and the carrying amount of the consideration paid by it, the capital surplus shall be adjusted. If the capital surplus is not sufficient to be offset, the retained earnings shall be adjusted. For a business combination not under same control, the asset, liability and contingent liability obtained from the acquirer shall be measured at the fair value on the acquisition date. The combination cost shall be the fair value, on the acquisition date, of the assets paid, the liabilities incurred or assumed and equity securities issued by the acquirer in exchange for the control of the acquire, and sum of all direct expenses(if the combination is achieved in stages, the combination cost shall be the sum of individual transaction). The difference when combination cost exceeds proportionate share of the fair value of identifiable net assets of acquire should be recognized as goodwill. If the combination cost is less than proportionate share of the fair value of identifiable net assets of acquiree, firstly, fair value of identifiable asset, liability or contingent liability shall be reviewed, and so the fair value of non-monetary assets or equity instruments issued in the combination consideration , after review, still the combination cost is less than proportionate share of the fair value of identifiable net assets of acquire, the difference should be recognized as non- operating income. 6. Method of preparation of consolidated financial statements All subsidiaries controlled by the Group and structured entities are within the consolidation scope. If subsidiaries adopt different accounting policy or have different accounting period from the parent company, appropriated adjustments shall be made in accordance with the Group policy in preparation of the consolidated financial statements. All significant intergroup transactions, outstanding balances and unrealized profit shall be eliminated in full when preparing the consolidated financial statements.

If a business consolidation under common control is finally achieved in stages, consolidation accounting method shall be disclosed additionally for the period in which the control is obtained. For example, if a business consolidation under common control is finally achieved in stages, when preparing the consolidated financial statements, adjustments shall be made for the current 37 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report consolidation status as if consolidation has always been there since the point when the ultimate controlling party starts to control.

Other comprehensive income, under equity method accounting rising from the interest held in acquiree in relation to the period before the acquisition, and changes in the value of its other equity other than net profit or loss, other comprehensive income and profit appropriation shall be transferred to investment gain or loss for the period in which the acquisition incurs, excluding the other comprehensive income from the movement on the remeasurement of ne asset or liability of defined benefit plan. When the Group partially disposes of the long –term equity investment in subsidiary without losing the control over it, in the consolidated financial statements, the difference, between disposals price and respective disposed value of share of net assets in the subsidiary since the acquisition date or combination date, shall be adjusted for capital surplus or share premium, no enough capital surplus, then adjusted for retained earnings. When the Group partially disposes of the long –term equity investment in subsidiary and lose the control over it, in preparation of consolidated financial statements, remaining share of interest in the subsidiary shall be remeasured on the date of losing control. Sum of the share disposal consideration and fair value of remaining portion of shareholding minus the share of the net assets in the subsidiary held based on the previous shareholding percentage since the acquisition date or combination date, the balance of above is recognized as investment gain/loss for the period and goodwill shall be written off accordingly. Other comprehensive income relevant to share investment 38 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report in subsidiary shall be transferred to investment gain /loss for the period on the date of losing control. When the Group partially disposes of the long –term equity investment in subsidiary and lose the control over it by stages, if all disposing transactions are bundled, each individual transaction shall be seen as a transaction of disposal of a subsidiary by losing control.

Financial assets and financial liabilities The company shall recognize a financial asset or a financial liability when the company becomes party to the contractual provisions of the instrument. (1) Financial assets 1) Classification, recognition and measurement The company shall classify financial assets as measured at amortized cost, fair value through other comprehensive income or fair value through profit or loss on the basis of both the company’s business model for managing the financial assets and the contractual cash flow characteristics of the financial asset. A financial asset shall be measured at amortized cost if both of the following conditions are met: ①the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows;②the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. At initial recognition, the company shall measure the financial asset at its fair value and take any transaction costs that are directly attributable to the financial asset into account. After initial recognition, the company shall measure the financial asset at amortized cost. A gain or loss on a financial asset that is measured at amortized cost and is not a hedged item shall be recognized in profit or loss when the financial asset is derecognized, impaired, involved in foreign exchange or amortized for any difference arising between the initial recognized amount and due amount by applying effective interest method. A financial asset shall be measured at fair value through other comprehensive income if both of the following conditions are met: ①the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets and ②the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. At initial recognition, the company shall measure this financial asset at its fair value and take any transaction costs that are directly attributable to the financial asset into account. A gain or loss on a financial asset that is measured at fair value through other comprehensive income and is not a hedged item shall be recognized in other comprehensive income apart from a gain or loss on credit loss, foreign exchange and interest of the financial asset calculated by effective interest method. Accumulated gain or loss previously in the other comprehensive income shall be out of it and accounted in the profit or loss account when the financial asset is derecognized. The company recognized interest revenue based on effective interest method. Interest revenue shall be calculated by applying the effective interest rate to the gross carrying amount of a financial asset, except for: ①purchased or originated credit-impaired financial assets. For those financial assets, 40 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report the company shall apply the credit-adjusted effective interest rate to the amortized cost of the financial asset from initial recognition. ②financial assets that are not purchased or originated credit- impaired financial assets but subsequently have become credit-impaired financial assets. For those financial assets, the company shall apply the effective interest rate to the amortized cost of the financial asset in subsequent reporting periods. The company designates an investment as fair value measured through other comprehensive income if an equity instrument held is not for trading. Once the decision is made, it is an irrevocable election. At initial recognition, the company shall measure the equity instrument investment not for trading at its fair value and take any transaction costs that are directly attributable to the financial asset into account. Any other gain or loss (including foreign exchange gain or loss) shall be accounted in other comprehensive income and shall not be subsequently transferred to profit or loss, unless the dividend received is accounted in profit or loss( excluding the recovered investment cost). Accumulated gain or loss previously in the other comprehensive income shall be out of it and into retained earnings when the financial asset is derecognized. Apart from classified as the amortized cost financial assets and as fair value through other comprehensive income financial assets, a financial asset is classified as fair value through profit or loss. At initial recognition, the company shall measure this financial asset at its fair value and take any transaction costs that are directly attributable to the financial asset into account. A financial asset shall be classified as fair value through profit or loss if it is recognized contingent consideration through business combination, which is not under same control situation. 2) Recognition and measurement of transfer of financial assets A financial asset is derecognized when any one of the following conditions is satisfied: ①the rights to receive cash flows from the asset is terminated, ②the financial asset has been transferred and the company transfers substantially all risks and rewards relating to the financial assets to the transferee, ③the financial asset has been transferred to the transferee, the company has given up its control of the financial asset although the company neither transfers nor retains all risks and rewards of the financial asset. In the case where the financial asset as a whole qualifies for the derecognition conditions, the difference between the carrying value of transferred financial asset and the sum of the consideration received for transfer and the accumulated amount of changes in fair value in respect of the amount of partial derecognition (the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding) , that was previously recorded under other comprehensive income is transferred into profit or loss for the period. In the case where only part of the financial asset qualifies for derecognition, the carrying amount of financial asset being transferred is allocated between the portions that to be derecognised and the portion that continued to be recognised according to their relative fair value. The difference between the amount of consideration received for the transfer and the accumulated amount of changes in fair 41 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report value that was previously recorded in other comprehensive income for the asset partially qualified for derecognition (the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding) and the above-mentioned allocated carrying amount is charged to profit or loss for the period. (2) Financial liabilities 1) Classification, basis for recognition and measurement Financial liabilities of the company are classified at initial recognition as “financial liabilities at fair value through profit or loss” and “other financial liabilities” on initial recognition. Financial liabilities at fair value through profit or loss include financial liabilities held for trading and those designated as fair value through profit or loss on initial recognition. They are subsequently measured at fair value. The net gain or loss arising from changes in fair value, dividends and interest paid related to such financial liabilities are recorded in profit or loss for the period in which they are incurred. Other financial liabilities shall be subsequently measured at amortized cost by applying effective interest method. The company shall classify a financial liability as a liability measured at amortized cost except the followings: ①financial liability measured at fair value through profit or loss including tradable financial liability (derivative instrument of financial liability included) and designated as financial liability measured at fair value through profit or loss ② financial assets transfers that do not qualify for derecognition or financial liability is formed from continuing involvement in transferred assets ③ financial guarantee contract not in the above category of ①or ② and loan commitment which is not in the category ① at the below the market loan rate. The company shall account the financial liability as it measured at fair value through profit or loss if the financial liability is formed by contingent consideration recognized by the buyer through business combination that is not under common control. 2) Financial liability derecognition A financial liability is derecognized when the underlying present obligations or part of it are discharged. Existing financial liability shall be derecognized and new financial liability shall be recognized when the company signs the agreement with creditor to undertake the new financial liability in replacement of existing financial liability, and the terms of agreement are different in substance. Any significant amendment to the agreement as a whole or part o it is made, then the existing liabilities or part of it shall be derecognized and financial liability after terms amendment shall be recognized as a new financial liability. The difference between the carrying amount of the financial liability derecognized and the consideration paid is recognized in profit or loss for the period. (3) Fair value measurement of financial asset and financial liability The company uses the price in the primary market for financial assets and liability fair value measurement, if no primary market exists, the price in the most advantageous market shall be used 42 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report for fair value measurement and applicable valuation techniques which enough data is available for and supported by other information shall be adopted. Input for fair value measurement has 3 levels: level 1 input is the unadjusted quoted price for identical asset or liability available at the active market on the measurement date; level 2 input is the directly or indirectly observable input for relevant asset or liability apart from level 1 input; level 3 input is the unobservable input for relevant asset or liability. (4) Financial asset and financial liability offset Financial asset and financial liability shall be presented in the balance sheet separately and cannot be offset, unless the following conditions are all met: ①the company has the legal right to recognized offset amount and the right is enforceable. ②the company plans to receive or a legal obligation to pay cash at net amount. (5) Distinguishment between financial liability and equity instrument and accounting financial liability and equity instrument shall be distinguished in accordance with the following standards: ① if the company cannot unconditionally avoid paying cash or financial asset to fulfil a contractual obligation, the contractual obligation is qualified or financial liability. For certain financial instrument, although there are no clear terms and conditions to include obligation of paying cash or other financial liability, contractual obligation may indirectly be formed through other terms and conditions. ② the company’s own equity instrument shall also be considered whether it is the substitute of cash, financial asset or it is the remaining equity, after the issuer deducts liability, enjoyed by the equity holder , if it must or can be used to settle a financial asset. If the former, the instrument is a financial liability of the issuer, otherwise it is an equity instrument of the issuer. In certain circumstances, financial instrument contract is classified as financial liability, if financial instrument contract specifies the company must or can use its own equity to settle the financial instrument, the contractual amount of right or obligation equals to that of the numbers of own equity instrument available or to be paid multiplied by fair value when settling, nevertheless the amount is fixed, or varied partially or fully based on the its own equity’s market price(such as interest rate, certain commodity’s or financial instrument’s price variance). When classifying a financial instrument (or its component) in the consolidated statements, the company takes all terms and conditions agreed by the group member and instrument holder into consideration. If the group due to the instrument, as a whole, bears settlement obligation by paying cash, other financial asset or other means resulted in financial liability, the instrument shall be classified as financial liability. If a financial instrument or its component is financial liability, any gain or loss, interest, dividend, and any gain or loss from buy back or refinancing shall be accounted in profit or loss. If a financial instrument or its component is an equity instrument, when it was issued(including refinancing), bought back, sold or withdrawn, any change shall be regarded as equity change and no fair value change shall be recognized. (6) Financial asset impairment 43 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report Based on expected credit loss, a financial asset measured at amortized cost, a debt instrument investment measured at FVTOCI and a contractual asset shall all be subject to impairment accounting and be recognized for impairment loss allowance if any impairment. Expected credit loss is the weighted average of credit losses with the respective risks of a default occurring as the weights. A credit loss herein is referred to as the present value, at original effective rate, of the difference between the contractual cash flows that are due to the company under the contract; and the cash flows that the company expects to receive, that's the present value of the total cash shortage. A financial asset shall be the present value, at credit adjusted effective rate, if it is a purchased or originated credit -impaired asset. The company adopts simplified approach for trade receivables, contract assets that do not contain a significant financing component, and shall always measure the loss allowance at an amount equal to lifetime expected credit losses. Impairment requirements is to assess whether credit risk has been significantly increased since initial recognition at each reporting date, if there have been significant increases in credit risk, the company shall measure the loss allowance for a financial instrument at an amount equal to the lifetime expected credit losses, at the reporting date, if the credit risk on a financial instrument has not increased significantly since initial recognition, the company shall measure the loss allowance for that financial instrument at an amount equal to 12month expected credit losses. When assessing expected credit losses, the company considers all reasonable and supportable information, including that which is forward-looking. The company shall measure expected credit losses of a financial instrument in a way that reflects: an unbiased and probabilityweighted amount that is determined by evaluating a range of possible outcomes; The time value of money; and reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions. The company directly lowers the book value of the financial asset when contractual cash flow cannot be fully or partially recollected within rational expectation any longer. The company also assesses the expected credit loss of financial asset measured at amortized cost based on aging portfolio, other than pastdue credit loss assessment based on individual item. 11. Notes receivable (1) Recognition of provision for impairment On the basis of expected credit loss, the company always measures the loss allowance at an amount equal to lifetime expected credit losses for notes receivables which do not contain a significant financing component and are generated in accordance with Revenue Standard- No 14 of Accounting Standard for Business Enterprise. (2) Expected credit loss risk portfolio assessment method based on portfolio 44 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report The company separately assesses the credit risk of financial assets which have significantly different the credit risk, such as receivable with dispute or involved in litigation and arbitration; There are clear signs indicating the debtor is unlikely to fulfill the repayment obligations of the receivables, etc. Apart from the financial asset to be assessed for credit risk separately, the company divides the financial assets into different group based on common characteristics of risk and assesses the risk based on the portfolio. Based on the acceptor credit risk of notes receivable as the common risk characteristics, it is divided into different categories and determined for expected credit loss accounting estimate policy. Portfolio category Expected credit loss accounting estimate policy Bank acceptance note portfolio Lower credit risk assessed by the management Commercial acceptance note Same as receivables and provided for excepted credit loss portfolio allowance Referring to the experience of historical credit losses, the company prepares a table comparing the aging of notes receivable with the fixed reserve rate to calculate the expected credit losses on this basis. The Company prepares the comparison table between receivables aging and expected credit loss rate within lifetime and work out the expected credit loss by reference to historical credit loss experience in combination with current situation and future forecast of economy condition. The company shall measure expected credit losses of a financial instrument in a way that reflects: an unbiased and probabilityweighted amount that is determined by evaluating a range of possible outcomes; The time value of money; and reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions. The company prepares the comparison table between receivables aging and fixed provision rate and work out the expected credit loss by reference to historical credit loss experience. On the balance sheet date, expected credit loss of receivable shall be calculated. If the expected credit loss is larger than the book value of the provision of receivable impairment, the difference shall be recognized as receivable impairment loss, debit to “credit impairment loss”, credit to “provision for bad debt”. Alternatively, the difference is recognized as impairment gain and reversed journal entry shall be made. Actually incurred credit loss shall be debit to “provision for bad debt”, credit to “notes receivable”, based on the approved amount to be written off as it is assured as uncollectible receivable. If the amount to be written off is bigger than the provision for impairment loss, the difference is debit to “credit impairment loss”. 12. Accounts receivable (1) Recognition of provision for impairment 45 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report On the basis of expected credit loss, the company always measures the loss allowance at an amount equal to lifetime expected credit losses for trade receivables which do not contain a significant financing component and are generated in accordance with Revenue Standard- No 14 of Accounting Standard for Business Enterprise.

Apart from the trade receivables and other receivables to be assessed for credit risk separately, based on the counterparty as the common risk characteristics, it is divided into different categories and determined for expected credit loss accounting estimate policy. Portfolio category Expected credit loss accounting estimate policy Related parties portfolio within the Lower credit risk assessed by the management consolidation Other related parties and non-related Provided for excepted credit loss allowance parties portfolio Referring to the experience of historical credit losses, the company prepares a table comparing the aging of accounts receivable with the fixed reserve rate to calculate the expected credit losses on this basis. On the balance sheet date, expected credit loss of receivable shall be calculated. If the expected credit loss is larger than the book value of the provision of receivable impairment, the difference shall be recognized as receivable impairment loss, debit to “credit impairment loss”, credit to “provision for bad debt”. Alternatively, the difference is recognized as impairment gain and reversed journal entry shall be made. Actually incurred credit loss shall be debit to “provision for bad debt”, credit to “receivable”, based on the approved amount to be written off as it is assured as uncollectible receivable. If the amount to be written off is bigger than the provision for impairment loss, the difference is debit to “credit impairment loss” 13. Receivables financing In the process of managing enterprise liquidity, the Company carries out endorsement transfer or discount of most of the notes receivable before maturity, and terminates the confirmation of the 46 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report discounted or endorsed notes receivable based on the fact that the Company has transferred almost all the risks and rewards of the relevant notes receivable to the relevant counterparty. The company's business model of managing notes receivable is aimed at both collecting the contract cash flow and selling the financial asset, so it is classified as the financial asset measured at fair value and its changes are included in other comprehensive income, and listed in the receivables financing. 14.Other receivable (1) Recognition of provision for impairment On the basis of expected credit loss, the company always measures the loss allowance at an amount equal to lifetime expected credit losses for trade receivables which do not contain a significant financing component and are generated in accordance with Revenue Standard- No 14 of Accounting Standard for Business Enterprise.

The company shall measure expected credit losses of a financial instrument in a way that reflects: an unbiased and probabilityweighted amount that is determined by evaluating a range of possible 47 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report outcomes; The time value of money; and reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions. The company prepares the comparison table between receivables aging and fixed provision rate and work out the expected credit loss by reference to historical credit loss experience. On the balance sheet date, expected credit loss of receivable shall be calculated. If the expected credit loss is larger than the book value of the provision of receivable impairment, the difference shall be recognized as receivable impairment loss, debit to “credit impairment loss”, credit to “provision for bad debt”. Alternatively, the difference is recognized as impairment gain and reversed journal entry shall be made. Actually incurred credit loss shall be debit to “provision for bad debt”, credit to “notes receivable”, “receivable”, “other receivable” based on the approved amount to be written off as it is assured as uncollectible receivable. If the amount to be written off is bigger than the provision for impairment loss, the difference is debit to “credit impairment loss” 15. Inventories Inventories are materials purchasing, raw material, variance of cost materials, low-valuable consumable, materials processed on commission, working-in-progress, semi-finished goods, variance of semi-finished goods, and finished goods, engineering construction etc. The inventories are processed on perpetual inventory system, and are measured at their actual cost on acquisition. Weighted average cost method is taken for measuring the inventory dispatched or used. Low value consumables and packaging materials is recognized in the income statement by one-off method. After yearend thorough inventory check, at the balance sheet date inventory impairment should be provided or adjusted according to inventory category. For the finished goods, raw material held for sale etc which shall be sold directly, the net realizable value should be confirmed at the estimated selling price less estimated selling expenses and related tax and expenses. The raw material held for production, its realizable value should be confirmed at the estimated selling price of finished goods less estimated cost of completion, estimated selling expenses and related tax. The net realizable value of inventories held for execution of sale contracts or labor contracts shall be calculated based on the contract price. If the quantities of inventories in the Group are more than quantities if inventories subscribed in the sales contracts, the net realizable value of the excessive part of the inventories should be calculated based on the general selling price. When the impairment indicators disappear, impairment provision shall be reversed and 16. Contract assets Contract assets are the rights of the Company to receive consideration for the goods it has transferred to the customer, and such rights are subject to factors other than the passage of time. If the Company sells two clearly distinguishable goods to a customer and is entitled to receive 48 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report payment for the delivery of one of the goods, but the payment is contingent on the delivery of the other goods, the Company regards the right to receive payment as a contract asset. The method for determining the expected credit loss of the contract assets shall refer to the description of notes receivable and accounts receivable in notes 11 and 12 above. Accounting method: the Company calculates the expected credit loss of the contract assets on the balance sheet date. If the expected credit loss is greater than the carrying amount of the current contract assets impairment provision, the Company will recognize the difference as an impairment loss and debit "credit impairment loss" and credit "Contract assets impairment provision". On the contrary, the Company recognizes the difference as impairment gain and makes opposite accounting records. If the Company actually suffers a credit loss and determines that the relevant contract assets cannot be recalled, and the write-off is approved, the Company shall debit "impairment provisions of contract assets" and credit "contract assets" according to the approved amount of write-off. If the amount of write-off is greater than the allowance for loss accrued, the difference shall be debited as "credit impairment loss". 17. Contract Cost (1) The method for determining the amount of assets related to the contract cost The Company's assets related to contract cost include contract performance cost and contract acquisition cost. Contract performance cost, that is, the cost of the Company to the contract, do not belong to other accounting standards for enterprises the scope of the specification, and satisfy the following conditions at the same time, as the performance contract cost recognized as an asset: the cost and a current or expected is directly related to the contract, including direct materials, direct labor, manufacturing cost (or similar fee), specific cost borne by the customer and only other cost arising from this contract; this cost increases the Company's future resources for performance obligations; the cost is expected to be recovered. Contract acquisition cost, that is, the incremental cost incurred by the Company to acquire the contract is expected to be recovered, shall be recognized as an asset as the contract acquisition cost; if the amortization period of the asset does not exceed one year, it shall be recorded into the current profit and loss at the time of occurrence. Incremental cost is cost (such as sales commissions, etc.) that the Company would not incur without obtaining a contract. Expenses incurred by the Company for the acquisition of the contract, in addition to the incremental cost expected to be recovered (such as travel expenses incurred whether the contract is acquired or not, etc.), shall be recorded into the current profit and loss when incurred, except those clearly borne by the customer. (2) Amortization of assets related to contract cost The assets related to the contract cost of the Company shall be amortized on the same basis as the commodity income recognition related to the assets and shall be recorded into the current profit and 49 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report loss. (3) Impairment of assets related to the contract cost When determining the impairment loss of assets related to the contract cost, the Company shall first determine the impairment loss of other assets related to the contract recognized in accordance with accounting standards for other relevant enterprises. If the carrying value is higher than the residual consideration expected to be obtained by the Company due to the transfer of the commodity related to the asset and the estimated cost to be incurred for the transfer of the commodity, the excess part shall be set aside for impairment loss and recognized as an asset impairment loss. If the foregoing difference is higher than the carrying amount of the asset, the carrying amount of the asset shall be converted back to the original provision for impairment of the asset and recorded into the current profit and loss. However, the carrying amount of the asset after conversion shall not exceed the carrying amount of the asset under the circumstance of no provision for impairment of the asset. 18. Long-term receivables (1) Confirmation method of impairment provisio On the basis of expected credit losses, the Company will always measure its loss provision in accordance with the amount equivalent to the expected credit losses in the entire duration for long- term receivables formed by transactions regulated by the Accounting Standards for Enterprises No. 14 - Income Standards that do not contain significant financing components. Measurement of expected credit losses. Expected credit loss refers to the weighted average of the credit loss of a financial instrument weighted by the risk of default. The credit loss herein refers to the difference between all contractual cash flows receivable under the contract and all cash flows expected to be received by the Company discounted at the original effective interest rate, i.e. the present value of all cash shortfalls. (2) A portfolio method to evaluate expected credit risk on the basis of portfolio The Company evaluates the credit risk of financial assets with significantly different credit risks, such as: long-term receivables that have disputes with the other party or involve litigation or arbitration; Other receivables where there is a clear indication that the debtor is likely to be unable to meet its obligations, etc. Except for financial assets for which credit risk is assessed individually, the Company divides financial assets into different groups based on common risk characteristics and evaluates credit risk on a portfolio basis. In addition to long-term receivables with single credit risk assessment, it is divided into different combinations based on the relationship between long-term receivables transaction objects as the common risk characteristics, and the expected credit loss accounting estimation policy is determined: 50 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report Accounting policy for expected credit loss of portfolio classification The related party portfolio management within the scope of the merger evaluates that such projects have low credit risk Other related parties and combinations of non-related parties shall draw impairment provisions in accordance with the expected loss rate With reference to historical credit loss experience and combined with the current situation and forecast of future economic conditions, the company prepares a comparison table between the age of long-term receivables and the expected credit loss rate of the entire duration to calculate the expected credit loss. The Company's method of measuring expected credit losses on financial instruments reflects factors such as: an unbiased probability weighted average amount determined by evaluating a range of possible outcomes; Time value of money; Reasonable and evidence-based information about past events, current conditions, and projections of future economic conditions that are available at no unnecessary additional cost or effort at the balance sheet date. The Company calculates the expected credit loss of long-term receivables on the balance sheet date. If the expected credit loss is greater than the carrying amount of the current impairment provision for long-term receivables, the Company recognizes the difference as the impairment loss for long- term receivables, debits the "credit impairment loss" and credits the "bad debt provision". Instead, the company recognizes the difference as an impairment gain and makes the opposite accounting record. If the company decides that the related long-term receivables cannot be collected due to the actual credit loss and is approved to cancel, the "bad debt reserve" and the "long-term receivables" shall be debited and credited according to the approved amount of write-off. If the write-off amount is greater than the loss provision already drawn, the difference will be debited to "credit impairment loss" on a regular basis. 19. Long-term equity investment Long term equity investments are the investment in subsidiary, in associated company and in joint venture. Joint control is the contractual agreement sharing of control over an economic activity by all participants or participants’ combination and decisions or policies relating to the operating activity of the entity require the unanimous consent of the parties sharing the control. Significant influence exists when the entity directly or indirectly owned 20% or more but less than 50% shares with voting rights in the investee company. If holding less than 20% voting rights, the entity shall also take other facts or circumstances into accounts when judging any significant influences. Factors and circumstances include: representation on the board of directors or equivalent governing body of the investee, participation in financial or operating activities policy-making 51 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report processes, material transactions between the investor and the investee, interchange of managerial personnel or provision of essential technical information. When control exists over an investee, the investee is a subsidiary of an entity. The initial investment cost for long-term equity investment acquired through business combination under common control, is the carrying amount presented in the consolidated financial statements of the share of net assets at the combination date in the acquired company. If the carrying amount of net assets at the combination date in the acquired company is negative, investment shall be recognized at zero. If the equity of investee under common control is acquired by stages and business combination incurs in the end, an entity shall disclose the accounting method for long-term equity investment in the parent financial statement as a supplemental. For example, if the equity of investee under common control is acquired by stages and business combination incurs in the end, and it’s a bundled transaction, the entity shall regard all transactions as a one for accounting. If it’s not a bundled transaction, the carrying amount presented in the consolidated financial statements of the share of net assets at the combination date in the acquired company since acquisition is determined as for the initial cost of long-term equity investment. The difference between the cost initially recognized and carrying amount of long-term equity investment prior to the business combination plus the newly paid consideration for further share acquired, and capital reserve shall be adjusted accordingly. If no enough capital reserve is available for adjustment, retain earnings shall be adjusted. If long-term equity investment is acquired through business combination not under common control, initial investment cost shall be the combination cost. If the equity of investee not under common control is acquired by stages and business combination incursion the end, an entity shall disclose the accounting method for long-term equity investment in the parent financial statement as a supplemental. If the equity investment of investee not under common control is acquired by stages and business combination incursion the end, and it’s a bundled transaction, the entity shall regard all transactions as a one for accounting. If it’s not a bundled transaction, the carrying amount of the equity investment held previously plus newly increased investment cost are taken as the initial investment cost under cost model. If equity investment is held under equity method before the acquisition date, other comprehensive income under equity method previously shall not be adjusted accordingly. When disposing of the investment, the entity shall adopt the same basis as the investee directly disposing of related assets or liability for accounting treatment. Equity held prior to acquisition date as available for sale financial assets under fair value model, accumulated change on fair value previously recorded in other comprehensive shall be transferred into investment gain/loss for the period. Apart from the long-term equity investments acquired through business combination mentioned above, the cost of investment for the long-term equity investments acquired by cash payment is the amount of cash paid. For long-term equity investment acquired by issuing equity instruments, the cost of investment is the fair value of the equity instrument issued. For long-term equity investment 52 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report injected to the entity by the investor, the investment cost is the consideration as specified in the relevant contract or agreement. The Group adopts cost method to account for investment in subsidiary and equity method for investment in joint venture and affiliate. Long-term equity investment subsequently measured under cost model shall increase the carrying amount of investment by adjusting the fair value of additional investment and relevant transaction expenses. Cash dividend or profit declared by investee shall be recognized as investment gain/loss for the period based on the proportion share in the investee. Long-term equity investment subsequently measured under equity method shall be adjusted for its carrying amount according to the share of equity increase or decrease in the investee. The entity shall recognize its share of the investee’s net profits or losses based on the fair value of the investee’s individual identifiable assets at the acquisition date, after making appropriate adjustments thereto in conformity with the accounting policies and accounting period, and offsetting the unrealized profit or loss from internal transactions entered into between the entity and its associates and joint ventures according to the shareholding attributable to the entity and accounted for as investment income and loss based on such basis. On disposal of a long-term equity investment, the difference between the carrying value and the consideration actually received is recognized as investment income for the period. For long-term investments accounted for under equity method, the movements of shareholder’s equity, other than the net profit or loss, of the investee company, previously recorded in the shareholder’s equity of the Company are recycled to investment income for the period on disposal. Where the entity has no longer joint control or significant influence in the investee company as a result of partially disposal of the investment, the remaining investment will be changed to be accounted for as available for sale financial assets, and the difference between the fair value of remaining investment at the date of losing joint control or significant influence and its carrying amount shall be recognized in the profit or loss for the year. Other comprehensive income recognized from previous equity investment under equity model shall be accounted for on the same basis as the investee directly disposing of related assets or liability when stopping using under equity model. Where the entity has no longer control over the investee company as a result of partially disposal of the investment, the remaining investment will be changed to be accounted for using equity method providing remaining joint control or significant influence over the investee company. The difference between carrying amount of disposed investment and consideration received actually shall be recognized in the profit and loss for the period as investment gain or loss, and investment shall be adjusted accordingly as if it was accounted for under equity model since acquisition. Where the entity has on longer joint control or significant influence in the investee as a result of disposal, the investment shall be changed to be accounted for as available for sale financial assets, and difference between the carrying amount and disposal consideration shall be recognized in profit and loss for 53 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report the period, and the difference between the fair value of remaining investment at the date of losing control and its carrying amount shall be recognized in the profit or loss for the year as investment gain or loss. If the entity loses its control through partially disposal of investment by stages and it’s not a bundled transaction, the entity shall account for all transactions separately. If it’s a bundled transaction, the entity shall regard all transactions as one disposal of subsidiary by losing control, but the difference between disposal consideration and carrying amount of the equity investment disposed prior to losing control, which arises from each individual transaction shall be recognized as other comprehensive income until being transferred into profit and loss for the period by the time of losing control. 20. Investment property The investment property includes property and building and measured at cost model Useful life Estimated net Category Annual depreciation rate (years) residual value rate Housing and Buildings 40 3% 2.43% 21. Fixed assets Recognition criteria of fixed assets: defined as the tangible assets which are held for the purpose of producing goods, rendering services, leasing or for operation & management, and have more than one year of useful life. Fixed assets shall be recognized when the economic benefit probably flows into the Group and its cost can be measured reliably. Fixed assets include: building, machinery, transportation equipment, electronic equipment and others. All fixed assets shall be depreciated unless the fixed assets had been fully depreciated and are still being used and land is separately measured. Straight-line depreciation method is adopted by the Group. Estimated net residual value rate, useful life, depreciation rate as follows: Useful life Estimated net Annual No Category (years) residual value rate depreciation rate 1 Housing and Buildings 20-40 3%,5%,10% 2.25-4.85% 2 Machinery equipment 10-22 3%,5%,10% 4.09-9.7% 3 Transportation equipment 4-15 3%,5%,10% 6-24.25% 4 Electronic equipment 5 3%,5%,10% 18-19.4% 5 Others equipment 10-15 3%,5%,10% 6-9.7% The Group should review the estimated useful life, estimated net residual value and depreciation method at the end of each year. If any change has occurred, it shall be regarded as a change in the accounting estimates. Finance lease shall be recognized when one of the conditions are met, (1) the ownership of the asset 54 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report belongs to the company when the lease term is due , (2) the company has the option to buy the asset and buy price is far lower than the fair value when exercising the option. (3) lease term is most of the asset life (4) no significant difference between the present value of minimum lease premium and fair value on the lease commencement date. On commencement date, leased asset shall be recognized at the lower of fair value and the PV of minimum lease payment, long term payable shall be recognized at the minimum lease payment and the difference is unrecognized financing expense. The depreciation policy of the leased fixed assets shall be consistent with that of the self-owned fixed assets. If the ownership of asset can be reliably acquired by the lease term due date, leased asset shall be depreciated through the expected service life, otherwise, it shall be depreciated within the lower of the lease term and expected service life of the asset. 22. Construction in progress The criteria and time spot of constructions in progress’s being transferred to fixed assets: Constructions in progress are carried down to fixed assets on their actual costs when completing and achieving estimated usable status. The fixed assets that have been completed and reached estimated usable status but have not yet been through completion and settlement procedures are charged to an account according to their estimate values; adjustment will be conducted upon confirmation of their actual values. The Group should withdraw depreciation in the next month after completion. 23. Borrowing costs The borrowing cost includes the interest expenses of the borrowing, amortization of underflow or overflow from borrowings, additional expenses and the foreign exchange profit and loss because of foreign currency borrowings. The borrowing costs incurred which can be directly attribute to the fixed assets, investments properties, inventories requesting over 1 year purchasing or manufacturing so to come into the expected condition of use or available for sale shall start to be capitalized when expenditure for the assets is being occurred, borrowing cost has occurred, necessary construction for bringing the assets into expected condition for use is in progress. The borrowing costs shall stop to be capitalized when the assets come into the expected condition of use or available for sale. The borrowing costs subsequently incurred should be recorded into profit and loss when occurred. The borrowing costs should temporarily stop being capitalized when there is an unusual stoppage of over consecutive 3 months during the purchase or produce of the capitalized assets, until the purchase or produce of the asset restart. The borrowing costs of special borrowings, deducting the interest revenue of unused borrowings kept in the bank or the investment income from transient investment should be capitalized. The capitalized amount of common borrowings should be calculated as follows: average assets expenditure of the accumulated assets expenditure excess the special borrowing, multiplied by the capital rate. The capital rate is the weighted average rate of the common borrowings. 24. Right of use assets 55 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report The right to use assets refers to the right of the Company as the lessee to use the leased assets during the lease term. (1) Initial measurement On the commencement date of the lease term, the Company shall make an initial measurement of the right to use assets at the cost. The cost includes the following four items: (1) The initial measurement amount of lease liabilities; (2) The amount of the lease payment paid on or before the commencement date of the lease term, if there is a lease incentive, will be deducted from the amount of the lease incentive already enjoyed; (3) The initial direct costs incurred, namely the incremental costs incurred to achieve the lease; (4) The cost expected to be incurred for the demolition and removal of the leased asset, the restoration of the leased asset site or the restoration of the leased asset to the state agreed in the lease terms, except those incurred for the production of inventory. (2) Follow-up measurement After the commencement of the lease term, the Company shall adopt the cost model to carry out subsequent measurement of the right to use assets, that is, to measure the right to use assets at the cost minus accumulated depreciation and accumulated impairment losses. If the Company re- measures the lease liabilities in accordance with the relevant provisions of the lease standards, the book value of the right to use assets shall be adjusted accordingly. Depreciation of usufruct assets From the commencement date of the lease term, the Company shall make depreciation of the usufruct. The usuary-use asset is usually depreciated in the month in which the lease begins (if the enterprise chooses to depreciate in the month in which the lease begins, it needs to be depreciated according to the specific situation described). The amount of depreciation deducted shall, according to the use of the usufruct, be included in the cost of the relevant asset or the current profit and loss. When determining the depreciation method of the right to use assets, the Company shall make a decision based on the expected consumption mode of the economic benefits related to the right to use assets, and shall calculate and deduct the depreciation of the right to use assets by the straight line method. In determining the depreciable life of the use-right assets, the Company shall follow the following principles: Where the ownership of the leased assets is reasonably determined at the end of the lease term, depreciation shall be accrued during the remaining service life of the leased assets; Where it is not reasonably certain that ownership of the leased asset will be acquired at the end of the lease term, depreciation shall be accrued within the shorter period of the lease term or the remaining useful life of the leased asset. Impairment of the right to use assets In case of impairment of the right to use assets, the Company shall carry out subsequent depreciation according to the book value of the right to use assets after deducting the impairment loss. 25. Intangible assets 56 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report The intangible assets of the Group refer to land use right and software. For acquired intangible assets, the actual cost are measured at actual price paid and relevant other expenses. The cost invested into intangible assets by investors shall be determined according to the stated value in the investment contract or agreement, except for those of unfair value in the contract or agreement. Land use right shall be amortized evenly within the amortization period since the remised date.ERP system software and other intangible assets are amortized over the shortest of their estimated useful life, contractual beneficial period and useful life specified in the law. Amortization charge is included in the cost of assets or expenses, as appropriate, for the period according to the usage of the assets. At the end of the year, for definite life of intangible assets, their estimated useful life and amortization method shall be assessed. Any change shall be treated as change on accounting estimate. 26. Impairment of long-term assets The Group assesses at each balance sheet date whether there is any indication that long-term equity investments, investment property, fixed assets, construction in progress and intangible assets with definite useful life may be impaired. If there is any indication that an asset may be impaired, the asset will be tested for impairment. Goodwill arising in a business combination and intangible asset with infinite useful life are tested for impairment annually no matter there is any indication of impairment or not. Estimate of recoverable amount is the higher of its fair value less costs to sell and the present value of the future cash flows expected to be derived from the asset. If the recoverable amount of an asset is less than its carrying amount, the carrying amount shall be impaired and the difference is recognised as an impairment loss and charged to profit or loss for the period. Once an impairment loss on the assets is recognised, it is not reversed in a subsequent period. After assets impairment loss is recognized, depreciation and amortisation of the impaired asset shall be adjusted in the following period so that the adjusted carrying amount(less expected residual value) can be depreciated and amortised systematically within the remaining life. When assessing goodwill for impairment, the carrying amount of goodwill shall be allocated evenly to the assets group or assets portfolio. When testing the assets group or assets portfolio including goodwill, if there is any indication of impairment , ignoring the goodwill and testing the assets group or assets portfolio alone so to work out the recoverable amount and comparing to its carrying amount and recognize the impairment loss. After that, testing the assets group or assets portfolio with goodwill together, comparing the carrying amount of the assets group or assets portfolio(including goodwill allocation) with recoverable amount , goodwill impairment shall be recognized when the recoverable amount is lower than its carrying amount. 27. Long-term deferred expenses Long-term deferred expenses of the Group refer to leasing expenses, redecoration expense and others. The expenses should be amortized evenly over the beneficial period. If the deferred expense 57 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report cannot take benefit for the future accounting period, the unamortized balance of the deferred expenses should be transferred into the current profit or loss. Leasing expenses will be amortized within 10 years and 30years; redecoration expense and others will be amortized within 3 years. 28. Contract liabilities Contract liabilities reflect the Company's obligation to transfer the goods to the customer on consideration received or receivable from the customer. Where the customer has paid the contract consideration or the Company has obtained the right to receive the contract consideration unconditionally before the transfer of the goods to the customer, the liability of the contract shall be recognized in accordance with the amount received or receivable at the earlier point between the actual payment made by the customer and the due payment. 29. Employee benefits Employee’s benefit comprises short-term benefit, post-employment benefit, termination benefit and other long-term employee’s benefit. Short-term benefit includes salary, bonus, allowance, welfare, social insurance, housing funds, labour union expense, staff training expense, during the period in which the service rendered by the employees, the actually incurred short term employee benefits shall be recognized as liability and shall be recognized in P&L or related cost of assets based on benefit objective allocated from the service rendered by employees. Post-employment benefits include the basic pension scheme and unemployment insurance etc. Based on the risk and obligation borne by the Group, post-employment benefits are classified into defined contribution plan and defined benefit plan. For defined contribution plan, liability shall be recognized based on the contributed amount made by the Group to separate entity at the balance sheet date in exchange of employee service for the period and it shall be recorded into current profit and loss account or relevant cost of assets in accordance with beneficial objective. Termination benefits are employee’s benefit payable as a result of either an entity’s decision to terminate an employee’s employment before the contract due date or an employee’s decision to accept voluntary redundancy in exchange for those benefits. An entity shall recognize the termination benefits as a liability and an expense at the earlier date when the entity cannot unilateral withdraw the termination benefits due to employment termination plan or due to redundancy suggestion, or when the entity can recognize the restructuring cost or expense arising from paying termination benefits. Other long-term employee’s benefit refers to all other employee benefits other than short-term benefit, post-employment benefit and termination benefit. If other long-term employee’s benefit is qualified as defined contribution plan, contribution made shall be recognized as liabilities accordingly for the period in which the service are rendered by the employee and recognized in the profit or loss for the current period or relevant cost of assets. Except other long-term employee’s benefit mentioned above, obligation arising from defined benefit plan 58 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report shall be recognized in the profit or loss for the current period or relevant cost of assets in accordance with the period when the service are rendered by the employee. 30. Lease liability (1) Initial measurement The company shall initially measure the liabilities of the lease according to the present value of the outstanding lease payments on the commencement date of the lease term. 1) Lease payment The lease payment amount refers to the amount paid by the Company to the Lessor in connection with the right to use the leased assets during the lease term, including: (1) Fixed payment amount and substantial fixed payment amount, less the amount related to the lease incentive where there is a lease incentive; (ii) variable lease payments dependent on indices or ratios, which are determined at the initial measurement on the basis of the indices or ratios on the commencement date of the lease; (3) The exercise price of the purchase option when the Company reasonably determines that the purchase option will be exercised; (4) The term of the lease reflects the amount of money to be paid for the termination of the lease option when the Company will exercise it; (5) The amount expected to be paid based on the residual value of the guarantee provided by the Company. 2) Discount rate When calculating the present value of the lease payments, the Company shall use the interest rate embedded in the lease as the discount rate, which is the interest rate at which the sum of the present value of the lease receipts and the present value of the unsecured residual value of the lessor is equal to the sum of the fair value of the leased asset and the initial direct expenses of the Lessor. If the company is unable to determine the inherent interest rate of the lease, the incremental borrowing rate shall be used as the discount rate. Such incremental borrowing rate shall mean the interest rate payable by the Company during a similar period under similar mortgage conditions in order to acquire assets with a value similar to that of the usuable-use assets under similar economic circumstances. The interest rate is related to: (1) the company's own situation, i.e., the company's solvency and credit standing; ② The term of the "loan", i.e. the lease term; (3) The amount of "borrowed" funds, that is, the amount of lease liabilities; (4) "collateral conditions", that is, the nature and quality of the underlying assets; (5) Economic environment, including the jurisdiction where the lessee is located, the valuation currency, the signing time of the contract, etc. The company's bank loan interest rate/related lease contract interest rate/the company's latest similar asset mortgage interest rate/the interest rate of bonds issued by the enterprise in the same period...... Based on the above adjustment factors to obtain the incremental borrowing rate. (2) Follow-up measurement On the commencement date of the lease term, the Company shall carry out subsequent measurement of the lease liabilities according to the following principles: (1) Increase the carrying amount of the lease liabilities when recognizing the interest of the lease liabilities; (2) Reduce the carrying amount 59 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report of lease liabilities when paying the lease payment; (3) When the lease payment changes due to revaluation or lease change, the book value of the lease liability shall be measured again. The Company shall calculate the interest expense of the lease liability in each period of the lease term at a fixed periodic interest rate and record it into the current profit and loss, except for those that should be capitalized. The periodic interest rate refers to the discount rate used by the Company for the initial measurement of lease liabilities, or the revised discount rate used by the Company for the remeasurement of lease liabilities due to changes in lease payments or changes in lease. (3) Re-measurement After the commencement of the lease term, in the event of any of the following circumstances, the Company shall re-measure the lease liabilities according to the present value of the lease payments after the change and adjust the book value of the usufruct accordingly. If the book value of the right to use assets has been reduced to zero, but the lease liabilities still need to be further reduced, the company shall record the remaining amount into the profits and losses of the current period. (1) Changes in the substantial fixed payment amount (in this case, the original discount rate is used to discount); (2) The estimated amount payable of the residual value changes (in this case, the original discount rate is used to discount); (3) Any change in the index or rate used to determine the lease payment (in which case the revised discount rate is used); (4) The evaluation result of the call option changes (in this case, the revised discount rate is used to discount); (5) Changes in the assessment result or actual exercise of the lease option to renew or terminate the lease option (in which case, the revised discount rate is used to discount the option). 31. Contingent liabilities When the Company has transactions such as commitment to externals, discounting the trade acceptance, unsettled litigation or arbitration which meets the following criterion, provision should be recognized: It is the Company's present obligation; carrying out the obligation will probably cause the Company's economic benefit outflow; the obligation can be reliably measured. Provision is originally measured on the best estimate of outflow for paying off the present obligations, and to consider the risk, uncertainty, time value of monetary relevant to contingent items. If the time value of monetary is significant, the best estimate will be determined by discounted cash outflow in the future. At each balance sheet date, the book value of provision is reviewed and adjustment will be made on the book value if there is any change, in order to reflect the current best estimate. When compensation from the 3rd party is expected for full or partial contingent liability settlement, the compensation shall be recognized as an asset separately and measured at no more than the book value of contingent liability. 32. Share based payment An equity-settled share-based payment in exchange for the employee’s services is measured at the fair value at the date when the equity instruments are granted to the employee. Such fair value during 60 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report the vesting period of service or before the prescribed exercisable conditions are achieved is recognised as relevant cost or expense on a straight-line during the vesting period based on the best estimated quantity of exercisable equity instruments, accordingly increase capital reserve. A cash-settled share-based payment is measured at the fair value at the date at which the Group incurred liabilities that are determined based on the price of the shares or other equity instruments. If it is immediately vested, the fair value of the liabilities at the date of grant is recognised as relevant cost or expense, and corresponding liabilities. If it is exercisable only when the vesting period of service is expired or the prescribed conditions are achieve, the fair value of liabilities undertaken by the Group are re-measured at each balance sheet date based on the best estimate of exercisable situation. The fair value of the liabilities is re-measured at each balance sheet date. Any changes are recognised in the profit or loss for the year. If the granted equity instruments are cancelled within the vesting period, the equity instrument shall be treated as accelerated vesting and the balance linked to the remaining vesting period shall be recognized in the profit or loss account, accordingly be recognized in the capital reserve. If employees or other parties can choose but fail to satisfy non-vesting conditions during the vesting period, the Company sees this as cancellation of granted equity instruments. 33. Revenue The revenue of the Company is mainly from sales of complete sets of equipment, engineering installation. The Company has performed the performance obligations in the contract, that is, when the customer obtains the control right of the relevant goods or services, the revenue is recognized. If the contract contains two or more performance obligations, the Company shall, at the beginning of the contract, allocate the transaction price to each individual performance obligation according to the relative proportion of the individual selling price of the commodities or services committed by each individual performance obligation, and measure the income according to the transaction price allocated to each individual performance obligation. The transaction price is the amount of consideration to which the Company is expected to be entitled as a result of the transfer of goods or services to the customer, excluding payments received on behalf of third parties. The trading price recognized by the Company shall not exceed the amount of accumulated recognized revenue that is highly unlikely to be materially reversed when the relevant uncertainties are eliminated. Refunds to customers are expected to be excluded from the transaction price as liabilities. Where there is a significant financing element in the contract, the Company shall determine the transaction price based on the amount payable by the assumed customer in cash upon acquisition of control over the goods or services. The difference between the transaction price and the contract consideration shall be amortized over the term of the contract using the effective interest rate method. On the commencement date of the contract, the Company expects that the interval between the customer's acquisition of control of the goods or services and 61 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report the customer's payment shall not exceed one year, regardless of the significant financing element existing in the contract. If one of the following conditions is met, the Company shall perform its performance obligations within a certain period of time; otherwise, the performance obligation shall be performed at a certain point: (1) When the customer performs the performance of the Company, it will obtain and consume the economic benefits brought by the performance of the Company. (2) The customer can control the commodities under construction during the performance of the Company. (3) The commodities produced by the Company during the performance of the contract shall have irreplaceable uses, and the Company shall have the right to receive payment for the accumulated performance part which has been completed so far during the entire contract period. For the performance obligations performed within a certain period of time, the Company shall recognize the income according to the performance progress within that period. If the performance schedule cannot be reasonably determined and the Company is expected to be compensated for the costs incurred, the revenue shall be recognized according to the amount of the cost incurred until the performance schedule can be reasonably determined. For performance obligations performed at a certain point, the Company recognizes revenue at the point when the customer acquires control over the relevant goods or services. In determining whether the customer has acquired control over the goods or services, the Company considers the following indications: (1). The Company shall have the right to receive the present payment for the goods or services. (2) The Company has transferred the legal ownership of the goods to the customer. (3) The Company has transferred the physical goods to the customer. (4) The Company has transferred to the customer the major risks and rewards in the ownership of the goods. (5) The customer has accepted the goods or services, etc. The Company determines whether it is the principal responsible person or the agent at the time of the transaction based on whether it has control over the commodity before transferring it to the customer. If the Company is able to control the commodity before transferring the commodity to the customer, the Company shall be the main person responsible and shall recognize the income according to the total amount received or the consideration; otherwise, the Company shall recognize the income according to the amount of the commission or handling charge to be entitled to be collected, which shall be the net amount after the total amount of consideration received or receivable is deducted from the price paid to other relevant parties, or determined according to the proportion of the established commission amount. The circumstances under which the Company 62 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report judges that it can control the goods before transferring them to the customer include: (1) The Company shall transfer the control right of commodities or other assets to the customer after the third party obtains the control right. (2) The Company can lead a third party to provide services to customers on behalf of the Company. (3) After the Company acquires the control of the commodity by a third party, it transfers the commodity to the customer by integrating it with other products into a group of outputs by providing significant services.

(2) The Company shall bear the inventory risk of the goods before or after the transfer of the goods. (3) The Company shall have the right to determine the prices of the commodities to be traded. (4) Other relevant facts and circumstances. The Company's right to receive consideration for the goods or services it has transferred to the customer (and such right is subject to factors other than the passage of time) is shown as a contract asset, and the impairment of the contract asset is calculated on the basis of the expected credit loss. The Company has the right to collect the consideration unconditionally from the customer as an account receivable. The obligation of the Company to transfer the goods or services to the customer upon receipt of the consideration receivable by the customer is shown as a contract liability. 34. Government grants A government grant shall be recognized when the Company complies with the conditions attaching to the grant and when the Company is able to receive the grant. Assets-related government grant is the government fund obtained by the Company for the purpose of long-term assets purchase and construction or establishment in the other forms. Income-related grants are the grant given by the government apart from the assets-related grants. If no grant objective indicated clearly in the government documents, the Company shall judge it according to the principle mentioned above. Where a government grant is in the form of a transfer of monetary asset, it is measured at the amount received. Where a government grant is made on the basis of fixed amount or conclusive evidence indicates relevant conditions for financial support are met and expect to probably receive the fund, it is measured at the amount receivable. Where a government grant is in the form of a transfer of non-monetary asset, it is measured at fair value. If fair value cannot be determined reliably, it is measured at a nominal amount of RMB1 Yuan. Assets-related government grants are recognized as deferred income ore directly offsetting the book value of the asset, and Assets-related government grants recognized as deferred income shall 63 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report be evenly amortized to profit or loss over the useful life of the related asset. Any assets are sold, transferred, disposed off or impaired earlier than their useful life expired date, the remaining balance of deferred income which hasn’t been allocated shall be carried forward to the income statement when the assets are disposed off. Income-related government grants that is a compensation for related expenses or losses to be incurred in subsequent periods are recognized as deferred income and credited to the relevant period when the related expense are incurred. Government grants relating to compensation for related expenses or losses already incurred are charged directly to the profit or loss for the period. Government grants related to daily business, shall be recognized as other income in accordance with business nature, otherwise, shall be recognized as non-operating expenses. If any government grant already recognized needs to be returned to the government, the accounting shall be differed according to the following circumstances: 1) originally recognized as offsetting of related assets' book value, assets book value shall be adjusted 2) if any deferred income, book value of deferred income shall be offset, excessive portion shall be accounted into income statement 3) Other situation, it shall be accounted into income statement directly. 35. Deferred tax assets and deferred tax liabilities The deferred income tax assets or the deferred income tax liabilities should be recognized according to the differences (temporary difference) between the carrying amount of the assets or liabilities and its tax base. Deferred tax assets shall be respectively recognized for deductible tax losses that can be carried forward in accordance with tax law requirements for deduction of taxable income in subsequent years. No deferred tax liabilities shall be recognized for any temporary difference arising from goodwill initially recognition. No deferred tax assets or liabilities shall be recognized for any difference arising from assets or liabilities initial recognition on non-business combination with no effect on either accounting profit or taxable profit (or deductible tax loss). At the balance sheet date, deferred tax assets and deferred tax liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or liability is settled. Deferred tax assets are recognized to the extent that it is probable that future taxable profit will be available to offset the deductible temporary difference, deductible loss and tax reduction. 36. Lease (1) Accounting treatment of operating leases (1) Identification of lease A lease is a contract whereby the lessor assigns the right to the use of an asset to the lessee for a certain period of time in exchange for consideration. On the commencement date of the contract, the Company evaluates whether the contract is a lease or includes a lease. A contract is a lease or 64 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report includes a lease if a party assigns the right to control the use of one or more identified assets for a certain period of time in exchange for consideration. To determine whether the contract relinquishes the right to control the use of the identified assets for a given period, the Company assesses whether the client under the contract is entitled to receive virtually all the economic benefits arising from the use of the identified assets during the use period and is entitled to dominate the use of the identified assets during the use period. If the contract contains multiple separate leases at the same time, the company will divide the contract and make accounting treatment for each separate lease. If the contract contains both leasing and non-leasing parts, the company shall split the leasing and non-leasing parts for accounting treatment. (2) The Company acts as the lessee On the commencement date of the lease term, the Company shall recognize the right to use assets and liabilities of the lease. The recognition and measurement of right to use assets and lease liabilities are shown in "27. Right to use Assets" and "33. Lease liabilities ". 2) Lease change Lease change refers to the change of lease scope, lease consideration and lease term beyond the terms of the original contract, including the increase or termination of the right to use one or more leased assets, the extension or shortening of the lease term stipulated in the contract, etc. The effective date of the lease change means the date on which the parties agree on the lease change. If the lease changes and the following conditions are met at the same time, the Company will treat the lease change as a separate lease for accounting: (1) The lease change expands the lease scope or the lease term by increasing the right to use one or more leased assets; (2) The increased consideration shall be equivalent to the amount of the individual price for the extended portion of the lease scope or the extended lease term adjusted for the circumstances of the contract. If the change of lease is not accounted for as a separate lease, the Company shall, on the effective date of the change of lease, apportion the consideration of the contract after the change in accordance with relevant provisions of the lease standards and redefine the lease period after the change; The revised discount rate is used to discount the changed lease payment amount to re-measure the lease liabilities. When calculating the present value of the lease payment after the change, the Company shall use the lease embedded interest rate during the remaining lease period as the discount rate; If it is not possible to determine the leasehold interest rate for the remaining lease term, the Company shall use the lessee's incremental borrowing rate on the effective date of the lease change as the discount rate. With respect to the impact of the above adjustment of lease liabilities, the Company will make accounting treatment according to the following circumstances: (1) If the change of lease results in the reduction of the scope of lease or the shortening of lease term, the lessee shall reduce the book value of the right to use assets and record the profits or losses related to partial or complete termination of lease into the current profit and loss. (2) If the lease liabilities are remeasured due to 65 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report other lease changes, the lessee shall adjust the book value of the right to use assets accordingly. 3) Short-term leases and leases of low-value assets For short-term leases with a lease term of no more than 12 months and low-value asset leases with a lower value when each leased asset is a new asset, the Company chooses not to recognize the right to use assets and lease liabilities. The Company will include the lease payments for short-term leases and leases of low-value assets into the cost of the relevant assets or current profits and losses during each period of the lease term in accordance with the straight-line method or other systematically reasonable method. (3) Our company is the lessor On the basis that this Contract is or includes a lease as assessed in (1), the Company, as the lessor, on the commencement date of the lease, divides the lease into a finance lease and an operating lease. If a lease substantially transfers almost all of the risks and rewards associated with ownership of the leased asset, the lessor classifies the lease as a finance lease and any lease other than finance lease as an operating lease. The Company generally classifies a lease as a finance lease if it has one or more of the following conditions: (1) At the end of the lease term, the ownership of the leased asset passes to the lessee; (2) The lessee has the option to purchase the leased asset, and the purchase price entered into is sufficiently low compared with the fair value of the leased asset at the time the option is expected to be exercised, so that it can be reasonably determined on the commencement date that the lessee will exercise the option; (3) Although the ownership of the asset is not transferred, the lease period accounts for most of the service life of the leased asset (no less than 75% of the service life of the leased asset); (4) On the lease commencement date, the present value of the lease receipts is almost equivalent to the fair value of the leased asset (not less than 90% of the fair value of the leased asset). ; ⑤ The leased assets are special in nature, and only the lessee can use them if there is no major transformation. The Company may also classify a lease as a finance lease if it has one or more of the following signs: (1) If the lessee cancels the lease, the lessee shall bear the loss caused to the lessor by the cancellation; (2) the profit or loss generated by the fluctuation of the fair value of the residual asset belongs to the lessee; (3) The lessee has the ability to continue the lease at a rent far below the market level until the next period. 2) Accounting treatment of operating lease Disposal of rent During each period of the lease term, the Company will use the straight-line method/other systematic and reasonable methods to recognize lease receipts from operating leases as rental income. Incentives offered If the rent-free period is provided, the Company shall allocate the total rent by the straight line method/other reasonable method throughout the lease period without deducting the rent-free period, 66 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report and shall recognize the rental income during the rent-free period. If the Company bears certain expenses of the Lessee, such expenses shall be deducted from the total rental income and distributed according to the balance of the rental income after deduction. Initial direct cost The initial direct expenses incurred by the Company in connection with the operating lease shall be capitalized to the cost of the underlying assets under lease and shall be booked into the current profits and losses in stages during the lease term on the same recognition basis as the rental income. Depreciation For the fixed assets in the operating leased assets, the Company shall adopt the depreciation policy for similar assets. Other operating leased assets shall be amortized in a systematic and reasonable manner. Variable lease payments The variable lease payments obtained by the Company in connection with the operating lease and not included in the lease receipts shall be recorded into the current profit and loss when actually incurred. Changes in operating leases If an operating lease changes, the Company will treat it as a new lease as of the effective date of the change, and the amount received in advance or receivable for the lease related to the lease before the change is regarded as the amount received for the new lease. (2) Accounting treatment of finance lease Initial measurement On the commencement date of the lease term, the Company shall recognize the finance lease receivable and terminate the recognition of the finance lease assets. In the initial measurement of the finance lease receivables, the Group shall take the net lease investment as the recorded value of the finance lease receivables. The net lease investment is the sum of the present value of the unsecured residual value and the lease receipts not yet received at the commencement of the lease period, discounted at the interest rate contained in the lease. Lease revenue refers to the amount of money that the lessor should collect from the lessee for the assignment of the right to use the leased assets during the lease term, including: (1) the fixed amount and substantial fixed amount payable by the lessee; If there is a lease incentive, the amount related to the lease incentive will be deducted; (ii) variable lease payments dependent on indices or ratios, which are initially measured according to the indices or ratios on the commencement date of the lease; (3) the exercise price of the option to buy, provided that it is reasonably determined that the lessee will exercise the option; (4) the amount to be paid by the lessee to exercise the termination option, provided that the lease term reflects that the lessee will exercise the termination option; (5) Guarantee residual value provided to the lessor by the lessee, 67 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report the party related to the lessee and an independent third party who has the economic ability to perform the guarantee obligation. Subsequent measurement The Company calculates and recognizes the interest income for each period of the lease term at a fixed periodic interest rate. The periodic interest rate, it is to point to determine the net investment in the lease use contains the discount rate (if relet, sublet's interest rate implicit in the lease cannot be determined, using the original leasing of the discount rate (adjustments according to the initial direct costs related to sublease)), or change in the financing lease is not as a separate lease accounting treatment, and meet if changes to take effect on the lease beginning date, The lease will be classified as a financial lease at the revised discount rate determined in accordance with the relevant provisions. Accounting treatment of lease changes If the finance lease changes and meets the following conditions at the same time, the Company will treat the change as a separate lease for accounting: (1) The change expands the scope of lease by increasing the right to use one or more leased assets; (2) The increased consideration shall be equivalent to the amount of the individual price of the expanded lease area adjusted for the circumstances of the contract. If the change of financing lease is not as a single lease accounting treatment, and meet if changes to take effect on the lease beginning date, the lease will be classified as an operating lease terms, the group since the day of the effect of the change of it as a new lease accounting treatment, and prior to the effect of the change of the net investment in the lease as the book value of the leased asset. 37. Other significant accounting policies, accounting Estimates When preparing the financial statements, the management needs to use accounting estimate and assumption, which will have effect on the application of accounting policy and amount of asset, liability, income and expense. The actual circumstance maybe differs from the estimates. The management needs to continuously assess the key assumption involved by estimate and the judgment on uncertainty. Effect on the accounting estimate shall be recognized during the period when estimate is changed and in future. The following accounting estimate and key assumption will trigger the significant risk of significant adjustment on the book value of asset and liability during the period of future. (1) Impairment of receivable Receivable is measured at amortized cost at the balance sheet date and assessed for any impairment indicator and the acutely amount of impairment. Objective evidence for impairment includes judgmental data of indicating significant decline of future cash flow of individual or group of receivable, indicating significant negative financial performance of debtors. Had receivable is recovered with certain proof, and in fact, it is relevant to the the matters subsequent to the the loss recognition, the impairment recognized before shall be reversed. 68 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report (2) Provision of inventory impairment Inventory is periodically evaluated at the net realizable value and any cost higher than NRV shall be recognized as inventory impairment loss. When evaluating the NRV, net realizable value is determined by deducting the expected selling expense and relative tax from the estimated selling price. When actual selling price or cost differs from the previous estimates, management will make adjustment on NRV. Therefore, the results based on the present experience may differ from the actual results, which caused the adjustment on the carrying amount of inventory in the book. Provision for inventory impairment may vary with the above reasons. Any adjustment on provision for inventory impairment will affect the income statement. (3) Provision of goodwill impairment Each year, goodwill shall be assessed for any impairment. Recoverable amount of assets group or asset portfolio including goodwill shall be the present value of future cash flow, which needs estimates for calculation. If management adjust the gross profit margin adopted by the present value of future cash flow calculation of assets group or asset portfolio, adjusted gross profit margin is lower than the margin applied, the impairment is required. If management adjust the discounting rate before tax applied by the present value of future cash flow calculation of assets group or asset portfolio, adjusted discounting rate before tax is higher than the rate applied, the impairment is required. If actual profit margin or discounting rate before tax is higher or lower than management’s estimate, any impairment recognized before can not be reversed. (4) Provision of fixed asset impairment At the balance sheet date, the management shall implement impairment test on buildings, plant and machinery etc which has any impairment indicator. The recoverable amount of FA is the higher of PV of future cash flow and net value of fair value after disposal cost, the calculation needs accounting estimate. If management adjust the gross profit margin adopted by the present value of future cash flow calculation of assets group or asset portfolio, adjusted gross profit margin is lower than the margin applied, the impairment is required. If management adjust the discounting rate before tax applied by the present value of future cash flow calculation of assets group or asset portfolio, adjusted discounting rate before tax is higher than the rate applied, the impairment is required. If actual profit margin or discounting rate before tax is higher or lower than management’s estimate, any impairment recognized before can not be reversed. (5) Recognition of deferred tax assets Estimate on deferred tax assets needs making estimation of taxable income and applied tax rate in 69 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report the following years in future. Whether deferred tax asset can be realized depends on the enough probable taxable profit obtained in future. Tax rate change in future and the timing of temporary difference reverse may also affect the income tax expense(income)and the balance of deferred tax. Any change of estimate described here will cause the deferred tax adjustment. (6) Useful life span of fixed assets and intangible assets At least every year end, the management shall review the useful life of FA and intangible assets. Expected useful life is based on the management’s experience on the same class of assets, with reference to the estimate applied in the industry in conjunction with expected technology development. When previous estimate significantly changed, depreciation and amortization in the future shall be adjusted accordingly. 38. Changes in Accounting Policies, Accounting Estimates None VI. Taxation 1.

Risk Related to Financial Instruments 一、Risks associated with financial instruments The main financial instruments of the Company include borrowings, accounts receivable, accounts payable, other non-current financial assets, etc. Please refer to Note VI for the detailed description of each financial instrument. The risks associated with these financial instruments and the risk management policies adopted by the Company to reduce these risks are described below. The management of the company manages and monitors these risk exposures to ensure that the above risks are controlled within a limited range. 1. Various risk management objectives and policies The company's goal in risk management is to achieve an appropriate balance between risks and benefits, minimize the negative impact of risks on the company's operating performance, and maximize the interests of shareholders and other equity investors. Based on this risk management objective, the basic strategy of the company's risk management is to identify and analyze the various risks faced by the company, establish an appropriate risk tolerance bottom line and carry out risk management, and monitor various risks in a timely and reliable manner. controlled within a limited range. (1) Market risk 1.The main business of the company is located in China, and the main business is settled in RMB. However, the foreign currency assets and liabilities recognized by the company and future foreign currency transactions (foreign currency assets and liabilities and foreign currency transactions are mainly denominated in USD, JPY, EUR, HKD and GBP) still have foreign exchange risks. The company's financial department is responsible for monitoring the company's foreign currency transactions and the scale of foreign currency assets and liabilities to minimize foreign exchange risks. The company did not sign any forward foreign exchange contracts or currency swap contracts during the year. As of June 30, 2023, the foreign currency financial assets and foreign currency financial liabilities held by the company converted into RMB are listed as follows: Items 30-06-2023 30-06-2022 Monetary fund-USD 6,613,996.57 3,524,626.68 116 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report Monetary fund-JPY 4,888,065.57 1,047,501.00 Monetary fund-EURO 887,924.59 - Monetary fund- GBP 1,624,909.94 - Receivable - GBP 1,624,909.94 - Receivable- USD 50,661,047.36 35,850,695.71 Receivable - JPY 5,152,357.26 920,181.22 Receivable - EURO 15,944,342.17 Payables -USD 2,997,473.05 5,414,277.32 Payables -EURO 95,469,307.25 Payables - JPY 1,873,402.54 1,938,707.73 The Company paid close attention to the effect on FX risk. 2) Interest rate risk The company's interest rate risk mainly arises from bank borrowings. Financial liabilities with floating interest rates expose the Company to cash flow interest rate risk, while financial liabilities with fixed interest rates expose the Company to fair value interest rate risk. The company determines the relative proportion of fixed-rate and floating-rate contracts based on the prevailing market conditions. As at June 30, 2023, the Company's interest-bearing debt consisted primarily of RMB denominated fixed-rate borrowing contracts in the amount of $809.55 million ($74,000 million as at December 31, 2022). The company's finance department continuously monitors the company's interest rate levels. Rising interest rates will increase the cost of new interest-bearing debt and the company's unpaid interest on floating-rate interest-bearing debt, and adversely affect the company's financial performance. The management will make timely adjustments based on the latest market conditions. Adjustments to reduce interest rate risk. The sensitive analysis: As of June 30, 2023, if the borrowing rate were to rise or fall by 50 basis points, while other factors remained constant, the company's net profit would decrease or increase by approximately RMB5.909 million. 3) Price risk The price risk faced by the Company is mainly commodity price risk. The company sells products at market prices. As the national economy enters the "new normal", the manufacturing industry is under greater economic downward pressure, and the sharp fluctuations in the prices of bulk materials have a certain impact on the company's operations. (2)Credit risk The company's credit risk mainly comes from monetary funds, notes receivable, accounts receivable, and other receivables. Management has established appropriate credit policies and continuously monitors exposure to these credit risks. 117 Bingshan Refrigeration & Heat Transfer Technologies Co., Ltd. 2023 Semiannual Report The monetary funds held by the company are mainly deposited in financial institutions such as commercial banks. The management believes that these commercial banks have high reputation and asset status and have low credit risk. The company adopts a limit policy to avoid credit risk to any financial institution. For accounts receivable, other receivables and notes receivable, the company sets relevant policies to control credit risk exposure. The company evaluates the customer's credit qualification and sets the corresponding credit period based on the customer's financial situation, the possibility of obtaining guarantees from third parties, credit history and other factors such as current market conditions. The company will regularly monitor the credit records of customers. For customers with bad credit records, the company will use written reminders, shorten the credit period or cancel the credit period, etc., to ensure that the company's overall credit risk is within a controllable range. As of June 30, 2023, the total amount of the top five accounts receivable of the company: 219,819,023.26 yuan. (3) Liquidity risk Liquidity risk is the risk that the company will not be able to meet its financial obligations on the due date. The Company's approach to managing liquidity risk is to ensure that there is sufficient liquidity to meet obligations when they fall due without causing unacceptable losses or damage to corporate reputation.
