[0061] In order to make the purpose, technical solutions and advantages of the present application clearer, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] As the duration of regional high-temperature events continues to extend and the comprehensive intensity further increases, the demand for refrigeration, that is, the demand for air conditioners, increases.

[0063] However, current air conditioners have serious problems in refrigeration applications, such as severe attenuation of the refrigeration capacity at ultra-high temperatures, extremely poor refrigeration effect in the low-frequency operation section, and high operation energy consumption, which no longer match the user's requirements for refrigeration comfort and energy conservation and consumption reduction. The staff obtains the exhaust temperatures under different working conditions and operating frequencies, and obtains the sample operating frequency and the sample optimal exhaust temperature. That is, under different working conditions and operating frequencies, there is an optimal exhaust temperature that enables the best refrigeration capacity of the air conditioner. However, the current target exhaust control strategy only performs linear calculations of the target exhaust at different frequencies by setting the lowest target exhaust and the highest target exhaust, without considering the influence of the working conditions and operating frequencies on the target exhaust, resulting in poor refrigeration effect and failure to achieve the best energy efficiency state of the system.

[0064] This application conducts research on the technology for improving the ultra-high temperature refrigeration capacity, proposes an optimal target exhaust control method suitable for full-condition and full-frequency wide-range refrigeration, explores the optimal target exhaust corresponding to different outdoor ambient temperatures and the internal laws, and formulates an optimal target exhaust control strategy according to the relevant laws among the outdoor ambient temperature, operating frequency, and target exhaust, greatly improving the high-temperature refrigeration capacity under different loads, enhancing the refrigeration efficiency, and reducing the energy consumption.

[0065] In one embodiment, as Figure 1 shown, an air conditioner exhaust control method is provided. Taking the application of this method to an air conditioner controller as an example, in this embodiment, the method includes the following steps:

[0066] Step 102, obtain the current operating frequency and the current exhaust temperature of the air conditioner.

[0067] Among them, the air conditioner includes a compressor, an evaporator, a condenser, and an air conditioner controller, etc. The compressor sucks in the low-pressure refrigerant vapor coming out of the evaporator, raises its pressure, and then sends it into the condenser. It condenses into a high-pressure liquid in the condenser, and after throttling through a throttle valve, it becomes a low-pressure liquid and is sent into the evaporator, where it absorbs heat and evaporates into a low-pressure vapor, thus completing the refrigeration cycle.

[0068] The current operating frequency refers to the operating frequency of the compressor monitored at the current moment after the air conditioner is turned on and running. The current exhaust temperature refers to the exhaust temperature of the exhaust pipe obtained at the current moment after the air conditioner is turned on and running.

[0069] Specifically, after the air conditioner is turned on and operates in the cooling mode, the air conditioner controller sends a running frequency acquisition instruction to the compressor. When the compressor receives the running frequency acquisition instruction, it monitors the running frequency of the compressor and sends the running frequency to the air conditioner controller, thereby obtaining the current running frequency. The air conditioner controller sends an exhaust temperature acquisition instruction to the exhaust pipe temperature sensor. When the exhaust pipe temperature sensor receives the exhaust temperature acquisition instruction, it measures the exhaust temperature and sends the exhaust temperature to the air conditioner controller. The air conditioner controller can also simultaneously send a running frequency acquisition instruction to the compressor and an exhaust temperature acquisition instruction to the exhaust pipe temperature sensor to obtain the current running frequency and the current exhaust temperature. The air conditioner controller can also send a running frequency acquisition instruction to the compressor and an exhaust temperature acquisition instruction to the exhaust pipe temperature sensor according to a preset monitoring frequency. For example, send a running frequency acquisition instruction to the compressor and an exhaust temperature acquisition instruction to the exhaust pipe temperature sensor every 1 minute.

[0070] The compressor and the exhaust pipe temperature sensor can also respectively collect the current running frequency and the current exhaust temperature in real time, and the air conditioner controller obtains the current running frequency and the current exhaust temperature collected by the compressor and the exhaust pipe temperature sensor according to a preset monitoring frequency. Further, the current exhaust temperature can also be collected by a temperature sensing bulb placed at the end of the exhaust pipe.

[0071] Step 104, determine the running frequency range according to the current running frequency.

[0072] Among them, the running frequency range includes the maximum running frequency, the minimum running frequency, and the intermediate running frequency. The maximum running frequency is the maximum allowable running frequency of the air conditioner, and the minimum running frequency is the minimum allowable running frequency of the air conditioner. The intermediate running frequency is the running frequency between the maximum running frequency and the minimum running frequency excluding the maximum running frequency and the minimum running frequency. Let F represent the current running frequency, F max represent the maximum running frequency, F min represent the minimum running frequency, then the running frequency range includes F min , F min < F < F max , F max .

[0073] Specifically, the air conditioner controller compares the current running frequency with the maximum running frequency and the minimum running frequency to determine the running frequency range corresponding to the current running frequency. If the current running frequency is equal to the maximum running frequency, the running frequency range is the maximum running frequency. If the current running frequency is equal to the minimum running frequency, the running frequency range is the minimum running frequency. If the current running frequency is greater than the minimum running frequency and less than the maximum running frequency, the running frequency range is the intermediate running frequency.

[0074] In a possible implementation, if the current operating frequency is greater than or equal to the maximum operating frequency, the operating frequency range is the maximum operating frequency; if the current operating frequency is less than or equal to the minimum operating frequency, the operating frequency range is the minimum operating frequency; if the current operating frequency is greater than the minimum operating frequency and less than the maximum operating frequency, the operating frequency range is the intermediate operating frequency.

[0075] Step 106: In the preset target exhaust temperature calculation equations, select the target exhaust temperature calculation expression corresponding to the operating frequency range.

[0076] Among them, the preset target exhaust temperature calculation equations are generated based on the sample operating frequency and the sample optimal exhaust temperature, and are obtained by the staff through analyzing the air conditioner operation data under different working conditions and operating frequencies. The preset target exhaust temperature calculation equations include the maximum exhaust temperature calculation expression, the minimum exhaust temperature calculation expression, and the intermediate exhaust temperature calculation expression. The maximum operating frequency corresponds to the maximum exhaust temperature calculation expression, the minimum operating frequency corresponds to the minimum exhaust temperature calculation expression, and the intermediate operating frequency corresponds to the intermediate exhaust temperature calculation expression.

[0077] Specifically, after the air conditioner controller determines the operating frequency range corresponding to the current operating frequency, according to the corresponding relationship between the operating frequency range and the exhaust temperature calculation expression, in the preset target exhaust temperature calculation equations, obtain the exhaust temperature calculation expression corresponding to the operating frequency range, and obtain the target exhaust temperature calculation expression.

[0078] Step 108: Calculate the target exhaust temperature according to the target exhaust temperature calculation expression.

[0079] Specifically, the air conditioner controller obtains the current working condition, and calculates by inputting the current working condition into the target exhaust temperature calculation expression to obtain the target exhaust temperature corresponding to the current operating frequency. Optionally, the current working condition includes the indoor ambient temperature and the outdoor ambient temperature. The current working condition may also include the condensing pipe temperature and the evaporating pipe temperature.

[0080] Step 110: Generate an exhaust control instruction according to the target exhaust temperature and the current exhaust temperature.

[0081] Among them, the exhaust control instruction refers to the opening adjustment instruction of the throttle control valve, including the adjustment of the opening size and the adjustment direction. The adjustment direction includes increasing and decreasing.

[0082] Specifically, the air conditioner controller determines the magnitude relationship between the target exhaust temperature and the current exhaust temperature, determines the opening of the throttle control valve according to the magnitude relationship between the target exhaust temperature and the current exhaust temperature, and generates an exhaust control instruction according to the opening of the throttle control valve and the current opening.

[0083] In the above air conditioner exhaust control method, the current operating frequency and the current exhaust temperature of the air conditioner are obtained; according to the current operating frequency, the operating frequency range is determined; in the preset target exhaust temperature calculation equation set, the target exhaust temperature calculation expression corresponding to the operating frequency range is selected; according to the target exhaust temperature calculation expression, the target exhaust temperature is calculated; according to the target exhaust temperature and the current exhaust temperature, an exhaust control instruction is generated. In the whole solution, for different operating frequencies, the corresponding target exhaust temperature calculation expression is selected to calculate the corresponding target exhaust temperature. Since the preset target exhaust temperature calculation equation set is generated based on the sample operating frequency and the sample optimal exhaust temperature, the target exhaust temperature corresponding to the current operating frequency can be calculated, and then the corresponding exhaust control instruction is generated according to the current exhaust temperature and the target exhaust temperature. The refrigeration adjustment for different operating frequencies is realized according to the exhaust control instruction, which can significantly improve the refrigeration effect.

[0084] In an alternative embodiment, as Figure 2 shown, calculating the target exhaust temperature according to the target exhaust temperature calculation expression includes:

[0085] Step 202, obtain the outdoor ambient temperature and the indoor ambient temperature.

[0086] Step 204, based on the target exhaust temperature calculation expression, calculate according to the outdoor ambient temperature and the indoor ambient temperature to obtain the target exhaust temperature.

[0087] Specifically, in the case where the current working condition includes the indoor ambient temperature and the outdoor ambient temperature, the air conditioner controller obtains the outdoor ambient temperature through the outdoor temperature sensor and obtains the indoor ambient temperature through the indoor temperature sensor, and inputs the outdoor ambient temperature and the indoor ambient temperature into the target exhaust temperature calculation expression for calculation to obtain the target exhaust temperature.

[0088] At this time, the maximum exhaust temperature calculation expression is constructed based on the linear relationship among the maximum operating frequency, the outdoor ambient temperature, and the indoor ambient temperature. Further, the maximum exhaust temperature calculation expression is obtained by weighted calculation based on the linear relationship among the maximum operating frequency, the outdoor ambient temperature, and the indoor ambient temperature. The maximum exhaust temperature calculation expression T max = aF max + bT 外环 + cT 内环 + d. Wherein, T max is the maximum target exhaust temperature, and the value range is 50 - 110 °C; F max is the maximum operating frequency, and the value range is 30 - 110 Hz; T 外环 is the outdoor ambient temperature, and the value range is -20 - 70 °C; T 内环is the outdoor ambient temperature, with a value range of 10 to 40 °C; a, b, c, and d are fitting coefficients obtained by fitting different air conditioner models.

[0089] The minimum exhaust temperature calculation expression is constructed based on the linear relationship among the minimum operating frequency, outdoor ambient temperature, and indoor ambient temperature. Further, the minimum exhaust temperature calculation expression is obtained by weighted calculation based on the linear relationship among the minimum operating frequency, outdoor ambient temperature, and indoor ambient temperature. The minimum exhaust temperature calculation expression T min = eF min + fT 外环 + gT 内环 + h; where T min is the minimum target exhaust temperature, with a value range of 30 to 50 °C; F min is the minimum operating frequency, with a value range of 0 to 30 Hz; T 外环 is the outdoor ambient temperature, with a value range of -20 to 70 °C; T 内环 is the outdoor ambient temperature, with a value range of 10 to 40 °C; e, f, g, and h are fitting coefficients obtained by fitting different models.

[0090] The intermediate exhaust temperature calculation expression is constructed based on the linear relationship among the maximum operating frequency, minimum operating frequency, current operating frequency, maximum target exhaust temperature, and minimum target exhaust temperature. Further, the minimum exhaust temperature calculation expression is obtained by weighted calculation based on the linear relationship among the maximum operating frequency, minimum operating frequency, current operating frequency, maximum target exhaust temperature, and minimum target exhaust temperature. The intermediate exhaust temperature calculation expression is:

[0091]

[0092] where T tar is the intermediate target exhaust temperature, with a value range of 30 to 110 °C, and F is the current operating frequency, with a value range of 0 to 110 Hz.

[0093] In this embodiment, the target exhaust temperature is calculated through the indoor ambient temperature, outdoor ambient temperature, and target exhaust temperature calculation expression, and the target exhaust temperature corresponding to different indoor and outdoor ambient temperatures can be obtained, thereby improving the accuracy of exhaust control.

[0094] In an alternative embodiment, as Figure 3 shown, according to the target exhaust temperature calculation expression, calculating the target exhaust temperature includes:

[0095] Step 302, obtain the condenser tube temperature and the evaporator tube temperature.

[0096] Step 304: Based on the target exhaust temperature calculation expression, calculate according to the condenser tube temperature and the evaporator tube temperature to obtain the target exhaust temperature.

[0097] Specifically, when the current working condition includes the condenser tube temperature and the evaporator tube temperature, use the condenser tube temperature to replace the outdoor ambient temperature and use the condenser tube temperature to replace the indoor ambient temperature. The air conditioner controller obtains the condenser tube temperature through the condenser tube temperature sensor and obtains the condenser tube temperature through the evaporator tube temperature sensor, and inputs the condenser tube temperature and the evaporator tube temperature into the target exhaust temperature calculation expression for calculation to obtain the target exhaust temperature.

[0098] At this time, the maximum exhaust temperature calculation expression is constructed based on the linear relationship among the maximum operating frequency, the condenser tube temperature, and the evaporator tube temperature. Further, the maximum exhaust temperature calculation expression is obtained by weighted calculation based on the linear relationship among the maximum operating frequency, the condenser tube temperature, and the evaporator tube temperature. The maximum exhaust temperature calculation expression T max = aF max + bT 冷 + cT 蒸 + d. Wherein, T max is the maximum target exhaust temperature, and the value range is 50-110 °C; F max is the maximum operating frequency, and the value range is 30-110 Hz; T 冷 is the condenser tube temperature, and the value range is -20-70 °C; T 蒸 is the condenser tube temperature, and the value range is 10-40 °C; a, b, c, d are fitting coefficients, which are obtained by fitting according to different air conditioner models.

[0099] The minimum exhaust temperature calculation expression is constructed based on the linear relationship among the minimum operating frequency, the condenser tube temperature, and the evaporator tube temperature. Further, the minimum exhaust temperature calculation expression is obtained by weighted calculation based on the linear relationship among the minimum operating frequency, the condenser tube temperature, and the evaporator tube temperature. The minimum exhaust temperature calculation expression T min = eF min + fT 冷 + gT 蒸 + h; wherein, T min is the minimum target exhaust temperature, and the value range is 30-50 °C; F min is the minimum operating frequency, and the value range is 0-30 Hz; T 冷 is the condenser tube temperature, and the value range is -20-70 °C; T 蒸 is the condenser tube temperature, and the value range is 10-40 °C; e, f, g, h are fitting coefficients, which are obtained by fitting according to different models.

[0100] The intermediate exhaust gas temperature calculation expression is constructed based on the linear relationship among the maximum operating frequency, the minimum operating frequency, the current operating frequency, the maximum target exhaust gas temperature, and the minimum target exhaust gas temperature. Further, the minimum exhaust gas temperature calculation expression is obtained by weighted calculation based on the linear relationship among the maximum operating frequency, the minimum operating frequency, the current operating frequency, the maximum target exhaust gas temperature, and the minimum target exhaust gas temperature. The intermediate exhaust gas temperature calculation expression is as follows:

[0101]

[0102] Where T tar is the intermediate target exhaust gas temperature, and its value range is 30 to 110 °C. F is the current operating frequency, and its value range is 0 to 110 Hz.

[0103] In this embodiment, by calculating the target exhaust gas temperature through the condensing pipe temperature, the evaporating pipe temperature, and the target exhaust gas temperature calculation expression, the target exhaust gas temperature corresponding to different condensing pipe temperatures and evaporating pipe temperatures can be obtained, thereby improving the accuracy of exhaust gas control.

[0104] In an alternative embodiment, in the preset target exhaust gas temperature calculation equation set, selecting the target exhaust gas temperature calculation expression corresponding to the operating frequency range includes: obtaining the outdoor ambient temperature; determining the outdoor ambient temperature range according to the outdoor ambient temperature; in the preset target exhaust gas temperature calculation equation set, selecting the target exhaust gas temperature calculation expression corresponding to the operating frequency range and the outdoor ambient temperature range.

[0105] Among them, the outdoor ambient temperature range includes multiple temperature ranges, and different temperature ranges can be set according to the specific ambient temperature. Different operating frequency ranges correspond to different temperature ranges. The weighting coefficients of the target exhaust gas temperature calculation expressions in different temperature ranges are different.

[0106] Specifically, the air conditioner controller obtains the preset temperature range corresponding to different operating frequency ranges, and obtains the outdoor ambient temperature. According to the preset temperature range corresponding to the operating frequency range and the outdoor ambient temperature, the outdoor ambient temperature range is determined, and then in the preset target exhaust gas temperature calculation equation set, the target exhaust gas temperature calculation expression corresponding to the operating frequency range and the outdoor ambient temperature range is obtained.

[0107] The maximum exhaust gas temperature calculation expression T max = a i F max + b i T 外环 + c i T 内环 + d i . Where T max is the maximum target exhaust gas temperature, and its value range is 50 to 110 °C; Fmax is the maximum operating frequency, with a value range of 30 - 110 Hz; T 外环 is the outdoor ambient temperature, with a value range of -20 - 70 °C; T 内环 is the outdoor ambient temperature, with a value range of 10 - 40 °C; a i , b i , c i , d i are fitting coefficients obtained by fitting according to different air conditioner models; i is the different coefficient taken for the corresponding different outdoor ambient temperature intervals, with a value range of 1 - 6. T A , T B , T C , T D , T E are the temperature values for dividing different intervals of the maximum allowable operating frequency according to the outdoor ambient temperature, with a value range of -20 - 70 °C.

[0108] The preset temperature intervals corresponding to the maximum operating frequency include (-20, T A , (T A , T B , (T B , T C , (T C , T D , (T D , T E , and (T E , 70]. The calculation expressions for the target exhaust gas temperature in different temperature intervals corresponding to the maximum operating frequency are shown in Table 1:

[0119] Among them, the condensing pipe temperature range includes multiple temperature ranges, and different temperature ranges can be set according to the specific ambient temperature, and different operating frequency ranges correspond to different temperature ranges. The weighted coefficients of the target exhaust gas temperature calculation expressions in different temperature ranges are different.

[0120] Specifically, the air conditioner controller obtains the preset temperature intervals corresponding to different operating frequency intervals, and obtains the condensing pipe temperature. According to the preset temperature intervals corresponding to the operating frequency intervals and the condensing pipe temperature, it determines the condensing pipe temperature interval, and further obtains the target exhaust temperature calculation expression corresponding to the operating frequency interval and the condensing pipe temperature interval in the preset target exhaust temperature calculation equation system.

[0121] The maximum exhaust temperature calculation expression T max = a i F max + b i T 冷 + c i T 蒸 + d i . Where T max is the maximum target exhaust temperature, and the value range is 50 - 110 °C; F max is the maximum operating frequency, and the value range is 30 - 110 Hz; T 冷 is the condensing pipe temperature, and the value range is -20 - 70 °C; T 蒸 is the evaporating pipe temperature, and the value range is 10 - 40 °C; a i , b i , c i , d i are fitting coefficients obtained by fitting different air conditioner models; i is the different coefficients taken for different condensing pipe temperature intervals, and the value range is 1 - 6.

[0125] Minimum exhaust gas temperature calculation expression T min = e j F min + f j T 冷 + g j T 蒸 + h j ; where T min is the minimum target exhaust gas temperature, and the value range is 30 to 50 °C; F min is the minimum allowable operating frequency, and the value range is 0 to 30 Hz; T 冷 is the condensing pipe temperature, and the value range is -20 to 70 °C; T 蒸 is the evaporating pipe temperature, and the value range is 10 to 40 °C; e j , f j , g j , h j are fitting coefficients obtained by fitting according to different models; j is the different coefficients taken for the corresponding different condensing pipe temperature intervals, and the value range is 1 to 4.

[0129] The intermediate exhaust gas temperature calculation expression is constructed based on the linear relationship among the maximum operating frequency, the minimum operating frequency, the current operating frequency, the maximum target exhaust gas temperature, and the minimum target exhaust gas temperature. Further, the minimum exhaust gas temperature calculation expression is obtained by weighted calculation based on the linear relationship among the maximum operating frequency, the minimum operating frequency, the current operating frequency, the maximum target exhaust gas temperature, and the minimum target exhaust gas temperature. The intermediate exhaust gas temperature calculation expression is:

[0130]

[0131] In this embodiment, the weighted coefficient of the target exhaust temperature calculation expression is determined by the temperature range of the condenser tube, and then the target exhaust temperature is calculated through the evaporation tube temperature, the condenser tube temperature, and the target exhaust temperature calculation expression, so that the target exhaust temperature corresponding to different indoor and outdoor environmental temperatures can be obtained, thereby improving the accuracy of exhaust control.

[0132] In an alternative embodiment, generating an exhaust control instruction according to the target exhaust temperature and the current exhaust temperature includes: obtaining an exhaust temperature difference according to the difference between the target exhaust temperature and the current exhaust temperature; determining a temperature difference range corresponding to the exhaust temperature difference; and generating an exhaust control instruction according to the temperature difference range.

[0133] Specifically, the air conditioner controller calculates the difference between the target exhaust temperature and the current exhaust temperature to obtain the exhaust temperature difference. Then, the air conditioner controller determines the temperature difference range corresponding to the exhaust temperature difference according to the preset exhaust temperature difference range and the exhaust temperature difference to obtain the target temperature difference range, and then obtains the opening adjustment instruction of the throttle control valve corresponding to the target temperature difference range.

[0134] Furthermore, the preset exhaust temperature difference range can be obtained by dividing according to the difference between the exhaust temperature and the target exhaust temperature of different air conditioner models. The preset exhaust temperature difference range includes (T d -T tar )≥△T1, △T1>(T d -T tar )≥△T2, △T2>(T d -T tar )≥△T3, △T3>(T d -T tar )≥△T4, and △T4>(T d -T tar ). If 1) (T d -T tar )≥△T1, the throttle control valve is opened wider by P1; 2) △T1>(T d -T tar )≥△T2, the throttle control valve is opened wider by P2; 3) △T2>(T d -T tar )≥△T3, the throttle control valve remains unchanged; 4) △T3>(T d -T tar )≥△T4, the throttle control valve is opened smaller by P3; 5) △T4>(T d -T tar), then the throttle control valve is opened smaller for P4. Wherein, △T1, △T2, △T3, and △T4 are the differences between the current exhaust gas temperature and the target exhaust gas temperature, and the value range is -20 to 20 °C; P1, P2, P3, and P4 are the throttle valve opening change values, and the value range is 0 to 20P. P1 > P2, P4 > P3, because (T d -T tar ) ≥ △T1 indicates that T d is positively deviated from the target exhaust gas temperature T tar by a large amount, and △T4 > (T d -T tar ) indicates that T d is negatively deviated from the target exhaust gas temperature T tar by a large amount. Therefore, the valve opening degrees in both cases are larger.

[0135] In this embodiment, by judging the temperature difference interval corresponding to the exhaust gas temperature difference, a more accurate exhaust gas control instruction can be obtained, thereby improving the accuracy of exhaust gas temperature control, greatly increasing the high-temperature refrigerating capacity under different loads, improving the refrigeration efficiency, and reducing the energy consumption.

[0136] In an alternative embodiment, generating an exhaust gas control instruction according to the temperature difference interval includes: obtaining the current exhaust gas temperature change rate; determining the throttle control valve opening degree according to the temperature difference interval and the current exhaust gas temperature change rate; and generating an exhaust gas control instruction according to the throttle control valve opening degree.

[0137] Specifically, the air conditioner controller can also combine the current exhaust gas temperature change rate and the preset exhaust gas temperature difference interval to determine the throttle control valve opening degree, and then generate a more accurate exhaust gas control instruction. Further, the air conditioner controller calculates the exhaust gas change value based on the exhaust gas temperature at the current moment and the exhaust gas temperature at the previous moment, and divides the exhaust gas change value by the time between the current moment and the previous moment to obtain the current exhaust gas temperature change rate. According to the corresponding relationship between the preset exhaust gas temperature difference interval, the current exhaust gas temperature change rate, and the throttle control valve opening degree adjustment, the throttle control valve opening degree is determined, and then an exhaust gas control instruction is generated according to the throttle control valve opening degree. The corresponding relationship between the preset exhaust gas temperature difference interval, the current exhaust gas temperature change rate, and the throttle control valve opening degree adjustment is shown in Table 5.

[0138] Table 5

[0139]

[0140] Wherein, △T1, △T2, △T3, and △T4 are the differences between the current exhaust gas temperature and the target exhaust gas temperature, and the value range is -20 to 20 °C; P5 to P 16 are the throttle valve opening change values, and the value range is 0 to 20P.

[0141] In this embodiment, by combining the temperature difference range and the current exhaust gas temperature change rate, a more accurate exhaust gas control instruction can be obtained, thereby improving the accuracy of exhaust gas temperature control, significantly increasing the high-temperature refrigerating capacity under different loads, enhancing the refrigeration efficiency, and reducing the energy consumption. In practical applications, according to the measured results, when the air conditioner exhaust gas temperature control method provided in this application is adopted, the refrigerating capacity during low-load operation in the high-temperature section can be increased by more than 30%.
