[0018] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] The energy-saving evaluation systems and standards established by different brands mainly serve the technical advantages of their own single brand or products, and cannot reflect the product technical advantages of other brands. For energy-saving technologies, users hope to understand the differences between products of different brands at the same level. However, the existing energy-saving evaluation systems and standards do not meet this requirement.

[0028] Specifically, when the manufacturers of air conditioner equipment promote the energy-saving effect of the equipment, they generally test the power consumption of the air conditioner when it operates in the conventional mode and when it operates in the energy-saving mode, and then use the difference between the two to evaluate the energy-saving advantage of the energy-saving algorithm of the tested air conditioner. However, this evaluation method does not consider that the energy-saving capabilities of air conditioners are not at the same level due to different hardware configurations of the air conditioners, that is, this method can only evaluate the energy-saving level of the energy-saving algorithm of the product itself, and the energy-saving levels between different devices cannot be directly compared.

[0029] Referring to Figure 1 , Figure 1 It is a flowchart of an air conditioner testing method shown according to an exemplary embodiment. As Figure 1 shown, the air conditioner testing method includes the following steps.

[0030] In step S101, the air conditioner to be tested is tested in an enthalpy difference laboratory, and the outdoor ambient temperature of the enthalpy difference laboratory is obtained.

[0031] In step S102, based on the outdoor ambient temperature and different reference test parameters of the air conditioner to be tested, the reference power consumption is determined. The different reference test parameters are obtained after the air conditioner to be tested operates under different standard operating conditions.

[0032] In step S103, based on the reference power consumption, the energy-saving evaluation information of the air conditioner to be tested is determined.

[0033] Exemplarily, the air conditioner to be tested is the air conditioner for which energy-saving evaluation is to be performed. The enthalpy difference laboratory is a laboratory for testing the performance of air conditioners. The enthalpy difference laboratory can accurately measure performance indicators such as the cooling capacity, heating capacity, and energy consumption of air conditioners, and can be used for the performance evaluation and energy efficiency testing of air conditioners. Among them, by controlling parameters such as the indoor and outdoor ambient temperature and humidity, the operating state of the air conditioner under different working conditions can be simulated to measure the energy efficiency and power consumption of the air conditioner, etc.

[0034] Exemplarily, the test space of the enthalpy difference laboratory may include an indoor space and an outdoor space. The environmental parameters of the indoor space and the outdoor space can be regulated by independent conditioners or by a common conditioner to meet the specified test conditions for air conditioner testing.

[0035] Exemplarily, the outdoor ambient temperature is the external ambient temperature simulated in the outdoor space of the enthalpy difference laboratory. The outdoor ambient temperature affects the operating state and energy consumption of the air conditioner. The reference test parameters are the parameters measured when the air conditioner to be tested operates under specific standard operating conditions. The reference power consumption is the power consumption of the air conditioner under standard operating conditions and can be used to measure the hardware performance of the air conditioner. The energy-saving evaluation information is determined based on the power consumption of the air conditioner under standard operating conditions and can be used to evaluate the energy-saving performance of the air conditioner.

[0036] Exemplarily, the different reference test parameters are obtained after the air conditioner to be tested operates under different standard operating conditions. For example, the reference test parameters may include the stable operating power obtained when the air conditioner is tested under the rated cooling condition, the minimum heating capacity obtained when the air conditioner is tested under the rated heating condition, the cooling energy efficiency ratio EER when the air conditioner operates at 25% of the rated cooling capacity, etc. For example, the reference test parameters include the operating power, cooling capacity, and cooling energy efficiency ratio EER of the air conditioner to be tested after operating for 1 h under the rated cooling power condition. For example, the reference test parameters include the operating power, heating capacity, and heating energy efficiency ratio COP of the air conditioner to be tested after operating for 1 h under the intermediate heating capacity condition.

[0037] Exemplarily, when determining which benchmark test parameters to use to determine the benchmark power consumption, the actual benchmark test parameters to be obtained can be determined according to the parameters in the standard formula for air conditioner power consumption test in the specified standard document, and based on the standard test conditions corresponding to the benchmark test parameters in the standard formula, the standard operating conditions of the air conditioner to be tested can be determined, and the air conditioner to be tested can be controlled to operate under the standard operating conditions to obtain the actual data of the benchmark test parameters.

[0038] In one example, different benchmark test parameters used for calculating the benchmark power consumption can be determined according to the specified standard document, such as the relevant test requirements in the national standard document "GB 21455-2019 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Room Air Conditioners". This is only an example and is not used to limit the present disclosure. It should be understood that other relevant documents with information that can be used to determine power consumption can also be used for the present disclosure.

[0039] Exemplarily, the energy-saving evaluation information can be used to characterize the energy-saving level of the energy-saving mode of the air conditioner to be tested relative to the benchmark power consumption, and can be used to characterize the energy-saving level of the normal mode of the air conditioner to be tested relative to the benchmark power consumption. In addition, the energy-saving evaluation information can also be used to characterize the difference in energy-saving level caused by the hardware difference information between two air conditioners.

[0040] Exemplarily, the benchmark test parameters are obtained by testing the air conditioner to be tested under standard operating conditions, and the standard operating conditions simulate the operating state of the air conditioner in a typical usage environment. Under the standard operating conditions, the operating mode and parameters of the air conditioner are fixed and do not involve dynamic adjustments of energy-saving algorithms such as variable frequency control and intelligent temperature control. For example, the air conditioner to be tested can be tested under fixed indoor and outdoor temperature, humidity and other conditions, and the air conditioner operates in a fixed operating mode, such as rated power operation, so as to obtain the benchmark test parameters corresponding to the air conditioner in this operating mode. Therefore, the benchmark power consumption determined based on the benchmark test parameters and the outdoor environmental temperature can accurately reflect the basic energy consumption level of the air conditioner hardware in actual use and is not affected by the actual control algorithm.

[0041] In this way, the benchmark power consumption can isolate the influence of the control algorithm, directly reflect the hardware performance of the air conditioner, and provide an intuitive hardware performance reference index for users. Users can compare the benchmark power consumption of different air conditioners and select products with better hardware performance, thereby reducing the long-term usage cost.

[0042] When the air conditioner to be tested is tested in an enthalpy difference laboratory, the reference power consumption is determined according to the outdoor environmental temperature of the enthalpy difference laboratory and different reference test parameters of the air conditioner to be tested, and the energy-saving evaluation information of the air conditioner to be tested is determined according to the reference power consumption. Among them, the reference test parameters are obtained by testing the air conditioner to be tested when it operates under different standard operating conditions. When the air conditioner to be tested operates in the enthalpy difference laboratory under the standard operating conditions, the operating mode and parameters of the air conditioner are fixed and do not involve dynamic adjustment in the energy-saving mode. Therefore, the reference power consumption is actually determined by the hardware performance of the air conditioner itself and can characterize the basic energy consumption level of the air conditioner to be tested. In this way, through the reference power consumption, it is helpful to evaluate the performance of the air conditioner more objectively.

[0043] In some embodiments, determining the reference power consumption according to the outdoor environmental temperature and different reference test parameters of the air conditioner to be tested includes: Determine the operating power of the air conditioner to be tested before and after the power switching moment according to the outdoor environmental temperature and the reference test parameters of the air conditioner to be tested before and after the power switching moment, and the power switching moment is determined according to the power stability duration when the air conditioner to be tested operates under different control modes; Determine the reference power consumption according to the operating power of the air conditioner to be tested before and after the power switching moment.

[0044] Exemplarily, the power switching moment is determined according to the power stability duration when the air conditioner operates under different control modes. Among them, the energy-saving capabilities corresponding to different control modes are different. Specifically, the operating powers corresponding to different control modes are different. For example, different control modes include a normal mode and an energy-saving mode, and the operating power corresponding to the energy-saving mode is less than the operating power corresponding to the normal mode.

[0045] Exemplarily, for different operating modes of the air conditioner, that is, in the cooling or heating mode of the air conditioner, there are different control modes. For example, for the heating mode of the air conditioner, different control modes may include a heating normal mode, a heating energy-saving mode, etc.; for the cooling mode of the air conditioner, different control modes may include a cooling normal mode, a cooling energy-saving mode, etc., which are not limited here.

[0046] Exemplarily, the operating power before the power switching moment can be determined according to the outdoor environmental temperature and the reference test parameters corresponding to the air conditioner to be tested before the power switching moment, and the operating power after the power switching moment can be determined according to the outdoor environmental temperature and the reference test parameters corresponding to the air conditioner to be tested after the power switching moment.

[0047] Exemplarily, under different reference operating conditions, the reference test parameters of the test air conditioner, such as operating power, cooling capacity, heating capacity, etc., can be determined in advance. Before and after the power switching moment, the corresponding operating power can be determined according to the corresponding reference test parameters.

[0048] For example, the power change after the air conditioner is turned on is not stable. Among them, when the air conditioner starts, it needs to quickly reach the set temperature, and components such as the compressor and the blower will operate at a relatively high power to quickly adjust the indoor temperature. During the steady-state operation stage, the operating power of the air conditioner is relatively stable, and the indoor temperature is mainly maintained stable by adjusting the cooling capacity and the energy efficiency ratio. As Figure 2 shown, the abscissa represents the operating duration of the air conditioner, and the ordinate represents the operating power of the air conditioner. Between the moment when the air conditioner is turned on and the moment t1, the operating power of the air conditioner first increases rapidly and then decreases, and the operating power tends to be stable between the moment t1 and the moment t2.

[0049] For example, before the power switching moment, the air conditioner is usually in the startup stage, and the air conditioner operates at a relatively high power to quickly reduce the indoor temperature. Therefore, using the stable operating power under the rated cooling condition can more realistically simulate the initial operating state of the air conditioner in actual use. After the power switching moment, the operating power of the air conditioner is mainly affected by the low-load demand for maintaining the temperature. Therefore, using parameters such as the cooling capacity and the cooling energy efficiency ratio EER at the stable time under the rated cooling condition can accurately be used to determine the operating power of the reference power consumption.

[0050] The present disclosure can more accurately measure the power consumption of the air conditioner under different working conditions by simulating the real outdoor environmental temperature in the enthalpy difference laboratory, improving the reliability of the test results. By using different reference test parameters before and after the power switching moment to determine the operating power of the air conditioner to be tested before and after the power switching moment, the reference power consumption can be more accurately determined, which can be used to evaluate the hardware performance and energy efficiency level of the air conditioner, eliminate the influence of the control algorithm, ensure that the test results only reflect the hardware performance, and provide a more objective evaluation basis for users to select energy-saving air conditioners.

[0051] In some embodiments, determining the operating power of the air conditioner to be tested before and after the power switching moment according to the outdoor environmental temperature and the reference test parameters of the air conditioner to be tested before and after the power switching moment includes: Determining the operating power of the air conditioner to be tested before the power switching moment according to the outdoor environmental temperature, and the first reference test parameter and the first power model corresponding to the air conditioner to be tested before the power switching moment; Determining the operating power of the air conditioner to be tested after the power switching moment according to the outdoor environmental temperature, and the second reference test parameter and the second power model corresponding to the air conditioner to be tested after the power switching moment, where the first power model and the second power model are different.

[0052] Exemplarily, the first benchmark test parameter is a parameter used to calculate the operating power consumption before the power switching moment. For example, parameters such as the stable operating power of an air conditioner under the rated cooling condition and the low-temperature cooling condition. The second benchmark test parameter is a parameter used to calculate the operating power consumption after the power switching moment. For example, parameters such as the cooling capacity and the energy efficiency ratio EER when the power of the air conditioner is stable under the rated cooling condition.

[0053] Exemplarily, the first power model is a mathematical model for calculating the operating power of an air conditioner based on the first benchmark test parameter and the outdoor ambient temperature before the power switching moment. The second power model is a mathematical model for calculating the operating power of an air conditioner based on the second benchmark test parameter and the outdoor ambient temperature after the power switching moment.

[0054] Exemplarily, before the power switching moment, the outdoor ambient temperature, the first benchmark test parameter, and the first power model are used to calculate the operating power; after the power switching moment, the outdoor ambient temperature, the second benchmark test parameter, and the second power model are used to calculate the operating power. Among them, the first benchmark test parameter and the second benchmark test parameter can be exactly the same parameter, can have some identical parameters, or can be completely different parameters.

[0055] In one example, when the first benchmark test parameter and the second benchmark test parameter are exactly the same, the model coefficients of the first power model and the second power model are different, or the relationship between the benchmark test parameters in the first power model and the second power model is different, which is not limited here.

[0056] The present disclosure can more accurately evaluate the power and power consumption of an air conditioner in different operating stages by using different benchmark test parameters and models before and after the power switching moment, and can improve the accuracy and reliability of the benchmark power consumption.

[0057] In some embodiments, when the air conditioner to be tested is in the heating mode, The first benchmark test parameter includes: the operating power under the power stable state obtained by testing the air conditioner to be tested under the rated cooling condition and the low-temperature cooling condition; wherein, the power stable state is used to characterize that the target power ratio of the air conditioner to be tested is less than or equal to a preset value, and the target power ratio is the ratio of the difference between the operating powers of the air conditioner to be tested at the first moment and the second moment to the operating power at the second moment. The second benchmark test parameter includes: the cooling capacity when the air conditioner to be tested is in the power stable state under the rated cooling condition; the energy efficiency ratio when the air conditioner to be tested operates at a specific cooling capacity at the first preset temperature and the second preset temperature, wherein the first preset temperature is different from the second preset temperature.

[0058] Exemplarily, the target power ratio is the ratio of the difference between the operating powers of the air conditioner under test at the first moment and the second moment to the operating power at the second moment. The target power ratio is used to characterize the power stability of the air conditioner. The preset value is used to determine whether the air conditioner has reached the power stable state. The preset value can be set according to actual test requirements. For example, the preset value can be set to 0.1.

[0059] Exemplarily, when the target power ratio is greater than the preset value, it indicates that the operating power of the air conditioner under test is not yet stable, that is, the current operating power of the air conditioner under test is not in the power stable state. When the target power ratio is less than or equal to the preset value, it indicates that the operating power of the air conditioner under test has been stable, that is, the current operating power of the air conditioner under test enters the power stable state.

[0060] Exemplarily, operating condition parameters such as the rated cooling condition, low-temperature cooling condition, and specific cooling capacity can be determined according to the relevant regulations of the air conditioner test standard document. Among them, the rated cooling condition is: the indoor ambient temperature is 27°C / 19°C, and the outdoor ambient temperature is 35°C / 24°C, where 27°C is the indoor dry-bulb temperature, 19°C is the indoor wet-bulb temperature, 35°C is the outdoor dry-bulb temperature, and 24°C is the outdoor wet-bulb temperature. The low-temperature cooling condition is: the indoor ambient temperature is 27°C / 19°C, and the outdoor ambient temperature is 29°C / 19°C, where 27°C is the indoor dry-bulb temperature, 19°C is the indoor wet-bulb temperature, 29°C is the outdoor dry-bulb temperature, and 19°C is the outdoor wet-bulb temperature. The specific cooling capacity includes 25% of the rated cooling capacity and the rated intermediate cooling capacity.

[0061] Exemplarily, the first preset temperature and the second preset temperature can be set according to actual test requirements. Or the first preset temperature and the second preset temperature can be obtained by pre-testing the air conditioner under test according to the regulations of the air conditioner test standard document. For example, the first preset temperature is the temperature when the indoor heat load reaches equilibrium with 25% of the rated cooling capacity of the air conditioner under test, and the second preset temperature is the outdoor ambient temperature when the indoor heat load reaches equilibrium with the rated intermediate cooling capacity of the air conditioner under test.

[0062] As an example, when the first reference test parameter includes the operating power in the power stable state obtained by testing the air conditioner under test under the rated cooling condition and the low-temperature cooling condition, the operating power of the air conditioner under test in the cooling mode and before the power switching moment can be determined by the following formula 1.

[0063] Formula 1: , where represents the operating power in the power stable state obtained by testing the air conditioner under test under the rated cooling condition in the enthalpy difference test chamber; represents the operating power in the power stable state obtained by testing the air conditioner under test under the low-temperature cooling condition in the enthalpy difference test chamber; Indicates the real-time outdoor ambient temperature of the enthalpy difference laboratory during the test of the benchmark power consumption.

[0064] As an example, when the second benchmark test parameters include the cooling capacity of the air conditioner under test in a stable power state under the rated cooling condition, and the energy efficiency ratio when the air conditioner under test operates at a specific cooling capacity at the first preset temperature and the second preset temperature, etc., the operating power of the air conditioner under test in the cooling mode after the power switching moment can be determined by Equation 2 as follows.

[0065] Equation 2: , where represents the cooling capacity of the air conditioner under test in a stable power state obtained by testing the air conditioner under test under the rated cooling condition in the enthalpy difference laboratory; represents when the outdoor ambient temperature is , the cooling energy efficiency ratio EER when the air conditioner under test operates at 25% of the rated cooling capacity, where is the outdoor ambient temperature when the indoor heat load of the enthalpy difference laboratory reaches equilibrium with 25% of the rated cooling capacity; represents when the outdoor ambient temperature is , the cooling energy efficiency ratio EER when the air conditioner under test operates at the rated cooling capacity, where is the outdoor ambient temperature when the indoor heat load of the enthalpy difference laboratory reaches equilibrium with the rated intermediate cooling capacity.

[0066] It can be understood that before testing the benchmark power consumption, the air conditioner under test can be tested through standard operating conditions such as the rated cooling condition, the low-temperature cooling condition, and the specific cooling capacity to obtain the operating power of the air conditioner under test in a stable power state under the rated cooling condition and the low-temperature cooling condition, the cooling capacity of the air conditioner under test in a stable power state under the rated cooling condition, and the energy efficiency ratio when the air conditioner under test operates at a specific cooling capacity at the first preset temperature and the second preset temperature, etc. When calculating the benchmark power consumption, based on the real-time obtained outdoor ambient temperature, the above parameters, and Equation 1 or Equation 2 above, the operating power of the air conditioner under test before the power switching moment can be determined, and the operating power of the air conditioner under test after the power switching moment can be determined, and the benchmark power consumption during the entire test process can be determined. Among them, the determination of the benchmark power consumption for the heating mode is also applicable in the same way, and will not be elaborated later.

[0067] In some embodiments, when the air conditioner under test is in the cooling mode, the first benchmark test parameters include: the minimum heating capacity when testing the air conditioner under test under the rated heating condition and the low-temperature heating condition, and the overall machine power when the air conditioner under test operates at the minimum heating capacity corresponding to the heating condition under the rated heating condition and the low-temperature heating condition; The second benchmark test parameters include: the energy efficiency ratio of the air conditioner under test when operating at the first specific heating capacity at the third preset temperature; the energy efficiency ratio of the air conditioner under test when operating at the second specific heating capacity at the fourth preset temperature.

[0068] Exemplarily, operating condition parameters such as the rated heating condition, the low-temperature heating condition, the first specific heating capacity, and the second specific heating capacity can be determined according to the relevant regulations of the air conditioner test standard document. Among them, the rated heating condition is: the indoor ambient temperature is 20°C / -, the outdoor ambient temperature is 7°C / 6°C, where 20°C is the indoor dry-bulb temperature, "-" indicates that the indoor wet-bulb temperature is not limited, 7°C is the outdoor dry-bulb temperature, and 6°C is the outdoor wet-bulb temperature. The low-temperature heating condition is: the indoor ambient temperature is 20°C / -, the outdoor ambient temperature is -7°C / -8°C, where 20°C is the indoor dry-bulb temperature, "-" indicates that the indoor wet-bulb temperature is not limited, -7°C is the outdoor dry-bulb temperature, and -8°C is the outdoor wet-bulb temperature. The first specific heating capacity and the second specific heating capacity can be 25% of the rated heating capacity and the intermediate heating capacity respectively.

[0069] Exemplarily, the third preset temperature and the fourth preset temperature can be set according to actual test requirements. Or the third preset temperature and the fourth preset temperature can be obtained in advance by testing the air conditioner under test according to the regulations of the air conditioner test standard document. For example, the third preset temperature is the intersection value of the 25% rated heating operation curve of the air conditioner under test and the heating building load within the non-frosting area of the air conditioner under test. The fourth preset temperature can be calculated based on the first intermediate heating capacity obtained by testing the air conditioner under test in the enthalpy difference laboratory under the rated heating condition, and the second intermediate heating capacity obtained by testing the air conditioner under test in the enthalpy difference laboratory under the low-temperature heating condition.

[0070] As an example, when the first benchmark test parameters include the minimum heating capacity when testing the air conditioner under test under the rated heating condition and the low-temperature heating condition, and the overall machine power when the air conditioner under test operates at the minimum heating capacity corresponding to the heating condition under the rated heating condition and the low-temperature heating condition, the operating power of the air conditioner under test in the heating mode and before the power switching moment can be determined by the following formula 3.

[0071] Formula 3: , where represents the minimum heating capacity obtained by testing the air conditioner under test under the rated heating condition in the enthalpy difference laboratory; represents the overall machine power obtained by testing the air conditioner under test when operating at the minimum heating capacity under the rated heating condition in the enthalpy difference laboratory; represents the minimum heating capacity obtained by testing the air conditioner under test under the low-temperature heating condition in the enthalpy difference laboratory; represents the overall machine power obtained by testing the air conditioner under test when operating at the minimum heating capacity under the low-temperature heating condition in the enthalpy difference laboratory.

[0072] As an example, when the second benchmark parameter includes the energy efficiency ratio when the air conditioner under test operates at the first specific heating capacity at the third preset temperature and the energy efficiency ratio when the air conditioner under test operates at the second specific heating capacity at the fourth preset temperature, the operating power of the air conditioner under test in the heating mode after the power switching moment can be determined by Equation 4 below.

[0073] Equation 4: . Wherein, represents the heating coefficient of performance COP when the air conditioner operates at 25% of its rated heating capacity in the non-frosting area of the air conditioner under test at the outdoor ambient temperature ; represents the intersection point of the 25% rated heating operation curve of the air conditioner and the heating building load in the non-frosting area; represents the heating coefficient of performance COP when the air conditioner operates at the intermediate heating capacity in the non-frosting area of the air conditioner at the outdoor ambient temperature ; represents the intermediate heating capacity obtained by testing the air conditioner under test under the low-temperature heating condition in the enthalpy difference test chamber; The calculation of

[0074] Equation 5: , wherein, represents the intermediate heating capacity obtained by testing the air conditioner under test under the rated heating condition in the enthalpy difference test chamber.

[0075] In some embodiments, before determining the operating power of the air conditioner under test before and after the power switching moment according to the outdoor ambient temperature and the benchmark test parameters of the air conditioner under test before and after the power switching moment, the method further includes: determining the target duration for the air conditioner under test to reach the power stable state from the start of operation in different control modes; wherein, the power stable state is used to represent that the target power ratio of the air conditioner under test is less than or equal to a preset value, and the target power ratio is the ratio of the difference between the operating powers of the air conditioner under test at the first moment and the second moment to the operating power at the second moment; determining the power switching moment according to the target duration corresponding to different control modes.

[0076] Exemplarily, the target duration is the time required for the air conditioner under test to reach the power stable state from the start of operation in different control modes. Among them, the air conditioner under test can be controlled to operate based on each control mode in advance, and the time required for the air conditioner under test to reach the power stable state from the start of operation in the control mode can be determined as the target duration of the control mode.

[0077] Exemplarily, the power stable state is used to characterize that the target power ratio of the air conditioner to be tested is less than or equal to a preset value, where the target power ratio is the ratio of the difference between the operating powers of the air conditioner to be tested at the first moment and the second moment to the operating power at the second moment. Herein, the interval between the first moment and the second moment can be a third preset duration, and the third preset duration can be, for example, 5 minutes or 10 minutes.

[0078] It can be understood that when controlling the air conditioner to be tested to operate based on each control mode, in order to ensure data consistency, the test conditions corresponding to the air conditioner to be tested are exactly the same, serving as a benchmark for evaluating the energy-saving level of the air conditioner. For example, when the control modes include the refrigeration normal mode and the refrigeration energy-saving mode, the rated refrigeration condition is used to test both the refrigeration normal mode and the refrigeration energy-saving mode. Among them, the rated refrigeration condition means the indoor ambient temperature is 27°C / 19°C and the outdoor ambient temperature is 35°C / 24°C. For example, when the control modes include the heating normal mode and the heating energy-saving mode, the rated heating condition is used for testing, and the rated refrigeration condition means the indoor ambient temperature is 10°C / - and the outdoor ambient temperature is 7°C / 6°C.

[0079] In some embodiments, determining the power switching moment according to the target duration corresponding to different control modes includes: determining the average value of the target durations corresponding to different control modes as the power switching moment.

[0080] Exemplarily, when the control modes include the refrigeration normal mode and the refrigeration energy-saving mode, the power switching moment corresponding to the refrigeration reference power consumption can be determined according to the power stable moments determined by actual tests in the refrigeration normal mode and the refrigeration energy-saving mode, that is, the target durations corresponding to the refrigeration normal mode and the refrigeration energy-saving mode.

[0081] For example, the power switching time during the refrigeration reference power consumption test of the air conditioner to be tested can be determined according to the average value of the target duration for the refrigeration normal mode of the air conditioner to be tested to enter the power stable state and the target duration for the refrigeration energy-saving mode to enter the power stable state. The power switching time during the heating reference power consumption test of the air conditioner to be tested can be determined according to the target duration for the heating normal mode of the air conditioner to be tested to enter the power stable state and the target duration for the heating energy-saving mode to enter the power stable state.

[0082] In some embodiments, the air conditioner to be tested includes a first air conditioner and a second air conditioner; determining the energy-saving evaluation information of the air conditioner to be tested according to the reference power consumption includes: Determining a first gap between the reference power consumptions of the first air conditioner and the second air conditioner; According to the first gap, determining first energy-saving evaluation information of the first air conditioner and the second air conditioner, where the first energy-saving evaluation information is used to characterize the difference in energy-saving degree caused by the hardware configuration differences between the first air conditioner and the second air conditioner.

[0083] Exemplarily, the energy-saving evaluation information is information for evaluating the energy-saving performance of an air conditioner based on data such as the baseline power consumption. The first energy-saving evaluation information is the energy-saving evaluation information determined according to the first gap, and can be used to characterize the difference in energy-saving degree caused by the hardware configuration differences between the first air conditioner and the second air conditioner.

[0084] Exemplarily, the first gap is the difference between the baseline power consumptions of the first air conditioner and the second air conditioner. This difference reflects the difference in energy-saving performance in the hardware configurations of the two air conditioners. For example, when the difference between the baseline power consumptions of the first air conditioner and the second air conditioner is greater than zero, it can indicate that the hardware configuration of the first air conditioner is superior to that of the second air conditioner. When the difference between the baseline power consumptions of the first air conditioner and the second air conditioner is less than zero, it can indicate that the hardware configuration of the second air conditioner is superior to that of the first air conditioner. When the difference between the baseline power consumptions of the first air conditioner and the second air conditioner is equal to zero, it can indicate that the overall hardware configurations of the first air conditioner and the second air conditioner are similar.

[0085] Exemplarily, under the same test conditions, the baseline power consumptions of the first air conditioner and the second air conditioner can be tested respectively. And the difference between the baseline power consumptions of the first air conditioner and the second air conditioner, that is, the first gap, can be determined. According to the first gap, the first energy-saving evaluation information of the first air conditioner and the second air conditioner can be determined. Through the first energy-saving evaluation information, the user can intuitively understand the difference in energy-saving performance in the hardware configurations of the two air conditioners.

[0086] The present disclosure can quantify the difference in energy-saving performance in the hardware configurations between the first air conditioner and the second air conditioner through the difference in the baseline power consumptions of different air conditioners, and provide a specific value or level, enabling the user to more intuitively understand the performance difference between the two air conditioners.

[0087] In some embodiments, the method further includes: Determining the target power consumption obtained by testing the air conditioner to be tested under different control modes; According to the baseline power consumption, determining the energy-saving evaluation information of the air conditioner to be tested, including: For the target control mode among different control modes, according to the baseline power consumption and the target power consumption corresponding to the target control mode, determining the second energy-saving evaluation information corresponding to the target control mode of the air conditioner to be tested, where the second energy-saving evaluation information is used to characterize the energy-saving degree corresponding to the control algorithm adopted by the control mode.

[0088] Exemplarily, the target power consumption is the power consumed by the air conditioner to be tested after running for a period of time under a specific control mode, and can be used to evaluate the energy consumption performance of the air conditioner to be tested under this control mode. The control modes include different operating modes of the air conditioner, such as the cooling mode, the heating mode, the energy-saving mode, the intelligent mode, the standard mode, etc. Under each control mode, the control algorithm of the air conditioner may be different, and there are differences in energy consumption corresponding to the control algorithms.

[0089] Exemplarily, the second energy-saving evaluation information is the energy-saving evaluation information determined based on the reference power consumption and the target power consumption under the target control mode. The second energy-saving evaluation information can be used to characterize the energy-saving degree corresponding to the control algorithm adopted by the control mode. Among them, the second energy-saving evaluation information can be a specific value, such as the energy-saving percentage, or a level, such as high, medium, low, etc.

[0090] Exemplarily, under different control modes, the power consumption of the air conditioner to be tested can be respectively measured, and the target power consumption under each control mode can be determined. Select any target control mode to be evaluated from different control modes, calculate the difference between the reference power consumption and the target power consumption corresponding to the target control mode, so as to determine the second energy-saving evaluation information corresponding to the target control mode.

[0091] Exemplarily, since the reference power consumption is the power consumption of the air conditioner under standard operating conditions, it can be used to measure the hardware performance of the air conditioner. By calculating the difference between the reference power consumption and the target power consumption under the target control mode, the energy-saving effect of the control algorithms adopted by different modes of the air conditioner can be quantified. This helps users more intuitively understand the energy-saving performance under different control modes.

[0092] Exemplarily, for the target control modes of the first air conditioner and the second air conditioner respectively, the second energy-saving evaluation information corresponding to the target control modes of the first air conditioner and the second air conditioner can be determined according to the reference power consumption and the target power consumption corresponding to the target control mode. Then, for the target control modes of the first air conditioner and the second air conditioner, a comparison can be made based on this second energy-saving evaluation information to compare the advantages and disadvantages of the control algorithms of the target control modes of the first air conditioner and the second air conditioner.

[0093] For example, when the target control mode is the energy-saving cooling mode, based on the air conditioner testing method of the present disclosure, the first reference power consumption corresponding to the first air conditioner and the second reference power consumption corresponding to the second air conditioner are respectively determined, and the first air conditioner and the second air conditioner are respectively controlled to run in the energy-saving cooling mode for testing, so as to obtain the first target power consumption corresponding to the first air conditioner and the second target power consumption corresponding to the second air conditioner. And based on the first difference between the first reference power consumption and the first target power consumption, and the second difference between the second reference power consumption and the second target power consumption, by comparing the magnitudes of the first difference and the second difference, the energy-saving levels corresponding to the energy-saving cooling modes of the first air conditioner and the second air conditioner can be determined.

[0094] Thus, based on the present disclosure, not only can the energy-saving effects of different control modes of the same air conditioner be evaluated more accurately, but also the differences in energy-saving degrees caused by different control algorithms of the same control mode of different air conditioners can be evaluated.

[0095] In some embodiments, the reference power consumption includes the reference heating power consumption and the reference cooling power consumption, and the target control modes include the heating normal mode, the cooling normal mode, the heating energy-saving mode, and the cooling energy-saving mode. Among them, the heating power of the heating energy-saving mode is lower than that of the heating normal mode, and the cooling power of the cooling energy-saving mode is lower than that of the cooling normal mode; according to the reference power consumption and the target power consumption corresponding to the target control mode, the second energy-saving evaluation information corresponding to the target control mode of the air conditioner to be tested is determined, including: determining the second energy-saving evaluation information corresponding to the heating normal mode according to the difference between the reference heating power consumption and the target power consumption corresponding to the heating normal mode; determining the second energy-saving evaluation information corresponding to the heating energy-saving mode according to the difference between the reference heating power consumption and the target power consumption corresponding to the heating energy-saving mode; determining the second energy-saving evaluation information corresponding to the cooling normal mode according to the difference between the reference cooling power consumption and the target power consumption corresponding to the cooling normal mode; determining the second energy-saving evaluation information corresponding to the cooling energy-saving mode according to the difference between the reference cooling power consumption and the target power consumption corresponding to the cooling energy-saving mode.

[0096] Exemplarily, the reference power consumption refers to the energy consumption level of the air conditioner when operating under standard conditions, and is used to evaluate the basic energy consumption performance of the air conditioner. The target control modes include: the heating normal mode, the cooling normal mode, the heating energy-saving mode, and the cooling energy-saving mode. Among them, the heating power of the heating energy-saving mode is lower than that of the heating normal mode, and the cooling power of the cooling energy-saving mode is lower than that of the cooling normal mode.

[0097] Exemplarily, by calculating the difference between the reference power consumption and the target power consumption under the target control mode, the energy-saving effect under different control modes can be determined. By calculating the difference between the reference power consumption and the target power consumption, the energy-saving effect under different control modes can be quantified. Users can select the most energy-saving control mode according to the second energy-saving evaluation information, optimize the usage method of the air conditioner, and improve user satisfaction.

[0098] In a specific example, as Figure 3 shown, the present disclosure proposes an air conditioner testing method to evaluate the energy-saving level of the air conditioner based on the reference power consumption.

[0099] Exemplarily, the air conditioner to be tested includes a household air source heat pump air conditioner, and the control modes of the air conditioner to be tested at least include the cooling normal mode, the heating normal mode, the cooling energy-saving mode, and the heating energy-saving mode.

[0100] Exemplarily, a laboratory for air conditioner testing includes at least an enthalpy difference laboratory, and in some embodiments, also includes a comfort laboratory. The comfort laboratory is a laboratory that simulates the user's home scenario and is mainly used to test the performance of the air conditioner in terms of comfort, such as temperature distribution, air flow organization, humidity control, etc. The enthalpy difference laboratory can accurately measure performance indicators such as the cooling capacity, heating capacity, and energy consumption of the air conditioner, and is mainly used for performance evaluation and energy efficiency testing. Among them, the test spaces of the enthalpy difference laboratory and the comfort laboratory can be divided into an indoor side space and an outdoor side space, and the environmental parameters of the indoor side space and the outdoor side space can be regulated by independent conditioners or by a common conditioner to achieve the specified test conditions that meet the air conditioner performance test.

[0101] In some embodiments, the power consumption tests of the refrigeration normal mode, heating normal mode, refrigeration energy-saving mode, and heating energy-saving mode of the air conditioner to be tested, as well as the refrigeration reference power consumption test and the heating reference power consumption test, can all be completed in the enthalpy difference laboratory.

[0102] In some embodiments, as Figure 4 shown, the power consumption tests of the refrigeration normal mode, heating normal mode, refrigeration energy-saving mode, and heating energy-saving mode of the air conditioner to be tested can be completed in the comfort laboratory, and the refrigeration reference power consumption test and the heating reference power consumption test can be completed in the enthalpy difference laboratory.

[0103] Among them, taking the Figure 4 shown test scenario as an example, the Figure 3 shown air conditioner test method will be described, where the air conditioner test method includes the following steps S31 - S38.

[0104] In step S31, the air conditioner to be tested completes the pre-test preparation work according to the test requirements and enters the reference power consumption test process.

Among them, the heating mode includes the heating normal mode, the heating energy-saving mode, and the heating reference power consumption test mode; the refrigeration mode includes the refrigeration normal mode, the refrigeration energy-saving mode, and the refrigeration reference power consumption test mode.

[0106] It can be understood that in order to ensure the consistency of data, when comparing the energy-saving capabilities of different air conditioners to be tested, different air conditioners to be tested use the same laboratory for testing during the test, and all other test conditions such as the installation positions of the indoor and outdoor units of the air conditioner to be tested and the layout of the installation environment remain in a consistent state.

[0107] In step S32, determine the test condition parameters according to the operating mode set for the air conditioner to be tested in step S321. In the embodiments of the present disclosure, the specific requirements for the test conditions are shown in Table 1 below.

[0108] Table 1 Test Condition Parameters Table

[0109] Among them, for the indoor conditions of the comfort laboratory, it is the initial condition at the startup moment of the air conditioner to be tested. At the startup moment of the air conditioner to be tested, the indoor condition machine of the comfort laboratory stops working, and only the indoor unit of the air conditioner to be tested works indoors to control the change of indoor environmental parameters.

[0110] Among them, for the outdoor conditions of the comfort laboratory, the environmental parameters are always maintained by the outdoor condition machine during the test. For the indoor and outdoor conditions of the enthalpy difference test chamber, the environmental parameters are always maintained by the indoor and outdoor condition machines during the test. The control accuracy of the dry bulb temperature and wet bulb temperature of the environment is ±0.3, and the control accuracy of the wall temperature is ±0.2. The running duration requirements for each test mode are satisfied for 8h.

[0111] In step S33, under the specified test conditions and test requirements, the power consumption tests in the refrigeration normal mode and the heating normal mode are carried out in the comfort laboratory.

[0112] Specifically, determine the time T1 when the air conditioner running power enters the power stable state through the time program for the air conditioner to be tested in the refrigeration normal mode and the heating normal mode.

[0113] In some embodiments, when the running duration of the air conditioner to be tested after startup is greater than the fourth preset duration, the time program retrieves the real-time running power P 1 (t) of the air conditioner to be tested and the running power P 1 (t - 5min) five minutes ago. When P 1 (t) and P 1 (t - 5min) meet the conditions corresponding to the following formula 6, it is considered that the time T1 when the air conditioner running power enters the power stable state is T1 = t - 5min.

[0114] Formula 6: .

[0115] Among them, the value range of the fourth preset duration can be 5min to 30min. The time when the air conditioner to be tested runs in the refrigeration normal mode and enters the power stable state is denoted as T1 cold .

And determine the total power consumption Q1 of the air conditioner to be tested running for the second preset duration in the refrigeration normal mode cold , and the total power consumption Q1 of the air conditioner to be tested running for the second preset duration in the heating normal mode heat .

[0116] In step S34, under the specified test conditions and requirements, the power consumption tests in the refrigeration energy-saving mode and the heating energy-saving mode are carried out in a comfort laboratory.

[0117] Specifically, for the air conditioner to be tested in the refrigeration energy-saving mode and the heating energy-saving mode, the time T2 when the operating power of the air conditioner enters the power stable state is determined through a time program.

[0118] In some embodiments, when the operating duration of the air conditioner to be tested is greater than the fourth preset duration, the time program retrieves the real-time operating power P 2 (t) of the air conditioner to be tested and the operating power P 2 (t - 5 min) five minutes ago. When P 2 (t) and P 2 (t - 5 min) first meet the conditions corresponding to Equation 7 below, it is considered that the time T2 when the operating power of the air conditioner enters the power stable state is t - 5 min.

[0119] Equation 7: 。

[0120] Among them, the value range of the fourth preset duration can be 5 min to 30 min. The time when the air conditioner to be tested operates in the refrigeration energy-saving mode and enters the power stable state is denoted as T2 cold 。The time when the air conditioner to be tested operates in the heating energy-saving mode and enters the power stable state is denoted as T2 heat 。And the total power consumption Q2 of the air conditioner to be tested when operating in the refrigeration energy-saving mode for the second preset duration is determined cold ,and the total power consumption Q2 of the air conditioner to be tested when operating in the heating energy-saving mode for the second preset duration heat 。

[0121] In step S35, according to T1 cold 、T1 heat 、T2 cold and T2 heat obtained in the above steps S33 - 34, the power switching moments during the refrigeration reference power consumption test and the heating reference power consumption test of the air conditioner to be tested are determined.

[0122] Among them, the power switching moment T3 cold during the refrigeration reference power consumption test of the air conditioner to be tested can be determined according to Equation 8.

[0123] Equation 8: 。

[0124] Among them, the power switching moment T3 heat during the heating reference power consumption test of the air conditioner to be tested can be determined according to Equation 9.

[0125] Equation 9: 。

[0126] In step S36, under specified test conditions and requirements, the refrigeration reference power consumption and the heating reference power consumption are tested in an enthalpy difference laboratory.

[0127] For the refrigeration reference power consumption test, when the operating time T of the air conditioner to be tested ≤ T3 cold the operating power of the air conditioner to be tested can be determined with reference to the above calculation formula 1, and the operating power at each moment before the power switching moment can be obtained. When the operating time T of the air conditioner to be tested > T3 cold the operating power of the air conditioner to be tested can be determined with reference to the above calculation formula 2, and the operating power at each moment after the power switching moment can be obtained. .

[0128] For the heating reference power consumption test, when the operating time T of the air conditioner to be tested ≤ T3 heat the operating power of the air conditioner to be tested can be determined with reference to the above calculation formula 3, and the operating power at each moment before the power switching moment can be obtained. When the operating time T of the air conditioner to be tested > T3 heat the operating power of the air conditioner to be tested can be determined with reference to the above calculation formulas 4-5, and the operating power at each moment after the power switching moment can be obtained. .

[0129] In step S37, according to the test method in the above step S36, the total power consumption consumed by the air conditioner to be tested during the refrigeration reference power consumption test and the heating reference power consumption test can be obtained. Among them, the total power consumption consumed by the air conditioner to be tested during the refrigeration reference power consumption test is denoted as Q3 cold ; the total power consumption consumed by the air conditioner to be tested during the heating reference power consumption test is denoted as Q3 heat .

[0130] In step S38, the energy-saving level of the air conditioner to be tested is evaluated.

[0131] Among them, the energy-saving level of the normal refrigeration mode of the air conditioner to be tested is . The energy-saving level of the normal heating mode of the air conditioner to be tested is . The energy-saving level of the energy-saving refrigeration mode of the air conditioner to be tested is . The energy-saving level of the energy-saving heating mode of the air conditioner to be tested is .

[0132] In this way, the reference power consumption can isolate the influence of the control algorithm, directly reflect the hardware performance of the air conditioner, and provide an intuitive hardware performance reference index for users. Users can compare the reference power consumption of different air conditioners and select products with better hardware performance, thereby reducing the long-term use cost.
