[0033] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for self-cleaning an air conditioner, comprising:

[0034] S101, in the case of self-cleaning operation, the air conditioner determines the phase current of the compressor.

[0035] S102, the air conditioner controls the air conditioner to adjust the opening of the throttle valve and the exhaust temperature according to the phase current of the compressor.

[0036] By adopting the method for self-cleaning of an air conditioner provided in the embodiment of the present disclosure, when the air conditioner is performing self-cleaning, if there are extreme operating conditions, such as high outdoor ambient temperature, the opening of the throttle valve and the exhaust temperature are adjusted according to the phase current of the compressor to avoid compressor frequency reduction or shutdown, so that the compressor can perform better and the frosting effect during the self-cleaning process can be more ideal, thereby improving the self-cleaning effect and enhancing the user experience.

[0037] Optionally, the air conditioner controls the air conditioner to adjust the opening of the throttle valve and the exhaust temperature according to the phase current of the compressor, including: the air conditioner controls the air conditioner to adjust the opening of the throttle valve and the exhaust temperature according to the outdoor ambient temperature and the phase current of the compressor. In this way, if the outdoor ambient temperature is high, the opening of the throttle valve and the exhaust temperature are adjusted according to the phase current of the compressor and the outdoor ambient temperature, so as to avoid the compressor from reducing the frequency or stopping, so that the compressor can play a better performance, and the frosting effect in the self-cleaning process is more ideal, thereby improving the self-cleaning effect and the user experience.

[0038] Optionally, the air conditioner controls the air conditioner to adjust the opening of the throttle valve and the exhaust temperature according to the outdoor ambient temperature and the phase current of the compressor, including: when the outdoor ambient temperature meets the extreme working condition, the air conditioner determines the magnitude relationship between the phase current of the compressor and the phase current threshold. According to the magnitude relationship between the phase current of the compressor and the phase current threshold, the air conditioner controls the air conditioner to adjust the opening of the throttle valve and the exhaust temperature. In this way, if the outdoor ambient temperature is high, it is first determined whether the outdoor ambient temperature meets the extreme working condition, and then the opening of the throttle valve and the exhaust temperature are adjusted according to the phase current of the compressor to avoid the compressor from reducing the frequency or shutting down, so that the compressor can play a better performance, and the frosting effect during the self-cleaning process is more ideal, thereby improving the self-cleaning effect and the user experience.

[0039] Optionally, the outdoor ambient temperature meets extreme operating conditions, including: the outdoor ambient temperature is greater than the temperature threshold. In this way, when the outdoor ambient temperature is high, if self-cleaning condensation and frosting are being performed, the load of the compressor may be high. If the throttle valve opening and exhaust temperature are adjusted to release the compressor load, the compressor may shut down or even cause damage to the air conditioner components. At this time, according to the phase current of the compressor, the throttle valve opening and exhaust temperature are adjusted to avoid compressor frequency reduction or shutdown, so that the compressor can perform better, and the frosting effect during the self-cleaning process is more ideal, thereby improving the self-cleaning effect and the user experience.

[0040] Optionally, the value of the temperature threshold can be 48°C. The value of the temperature threshold can be adjusted and set according to the properties of the air conditioner, which are not listed here one by one. In this way, an outdoor ambient temperature greater than 48°C is judged as a high temperature operating condition. At this time, if self-cleaning condensation and frosting are in progress, the load of the compressor may be high. If the throttle valve opening and the exhaust temperature are adjusted to release the compressor load, the compressor may shut down or even cause damage to the air conditioner components. At this time, according to the phase current of the compressor, the throttle valve opening and the exhaust temperature are adjusted to avoid compressor frequency reduction or shutdown, so that the compressor can perform better, and the frosting effect during the self-cleaning process is more ideal, thereby improving the self-cleaning effect and the user experience.

[0041] Optionally, the air conditioner controls the air conditioner to adjust the opening of the throttle valve and the exhaust temperature according to the magnitude relationship between the phase current of the compressor and the phase current threshold, including: when the phase current of the compressor is greater than the phase current threshold, the air conditioner controls the air conditioner to increase the opening of the throttle valve and reduce the exhaust temperature. When the phase current of the compressor is less than or equal to the phase current threshold, the air conditioner controls the air conditioner to reduce the opening of the throttle valve and increase the exhaust temperature. In this way, if the outdoor ambient temperature is high, if the phase current of the compressor is higher than the phase current threshold when self-cleaning condensation and frosting is performed, it means that the load of the compressor is large at this time, and it is necessary to control the air conditioner to increase the opening of the throttle valve and reduce the exhaust temperature to better release the load of the compressor, so as to better ensure that the compressor components are not damaged. If the phase current of the compressor is lower and less than or equal to the phase current threshold, it means that there is still a large margin in the compressor load at this time. At this time, the air conditioner is controlled to reduce the opening of the throttle valve and increase the exhaust temperature, so as to better perform frosting and condensation to improve the self-cleaning effect. It helps to avoid compressor frequency reduction or shutdown, enables the compressor to perform better, and makes the frosting effect more ideal during the self-cleaning process, thereby improving the self-cleaning effect and user experience.

[0042] Optionally, the value of the phase current threshold can be 4.8A. The value of the phase current can be adjusted and set according to the properties of the air conditioner, which are not listed here one by one. In this way, if the outdoor ambient temperature is high, if the phase current of the compressor is higher than 4.8A during self-cleaning condensation and frosting, it means that the load of the compressor is large at this time, and it is necessary to control the air conditioner to increase the opening of the throttle valve and reduce the exhaust temperature to better release the load of the compressor, so as to better ensure that the compressor components are not damaged. If the phase current of the compressor is low and less than or equal to 4.8A, it means that there is still a large margin in the compressor load at this time. At this time, the air conditioner is controlled to reduce the opening of the throttle valve and increase the exhaust temperature, so as to better perform frosting and condensation to improve the self-cleaning effect. It is beneficial to avoid compressor frequency reduction or shutdown, so that the compressor can perform better, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.

[0043] Optionally, the air conditioner controls the air conditioner to increase the opening of the throttle valve, including: the air conditioner controls the air conditioner to increase the opening of the throttle valve by the opening change value. In this way, if the outdoor ambient temperature is high, if the self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is higher than 4.8A, it is beneficial to better control the air conditioner to increase the opening of the throttle valve to better release the load of the compressor, so as to better ensure that the compressor components are not damaged. It is beneficial to avoid compressor frequency reduction or shutdown, so that the compressor can play a better performance, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.

[0044] Optionally, the value of the opening change value can be 10 steps. The value of the opening change value can be adjusted and set according to the properties of the air conditioner, which are not listed here one by one. In this way, if the outdoor ambient temperature is high, if self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is higher than 4.8A, the air conditioner is controlled to increase the opening of the throttle valve by 10 steps, which is conducive to better controlling the air conditioner to increase the opening of the throttle valve, so as to better release the load of the compressor, so as to better ensure that the compressor components are not damaged. It is conducive to avoiding compressor frequency reduction or shutdown, making the compressor perform better, and making the frosting effect more ideal during the self-cleaning process, improving the self-cleaning effect, and improving the user experience.

[0045] Optionally, the air conditioner controls the air conditioner to reduce the opening of the throttle valve, including: the air conditioner controls the air conditioner to reduce the opening of the throttle valve by the opening change value. In this way, if the outdoor ambient temperature is high, if the self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is low and is less than or equal to 4.8A, it is beneficial to better control the air conditioner to reduce the opening of the throttle valve, and better perform frosting and condensation to improve the self-cleaning effect. It is beneficial to avoid compressor frequency reduction or shutdown, so that the compressor can play a better performance, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.

[0046] Optionally, the value of the opening change value can be 10 steps. The value of the opening change value can be adjusted and set according to the properties of the air conditioner, which are not listed here one by one. In this way, if the outdoor ambient temperature is high, if self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is low and is less than or equal to 4.8A, the air conditioner is controlled to reduce the opening of the throttle valve by 10 steps, which is conducive to better controlling the air conditioner to reduce the opening of the throttle valve, and better frosting and condensation to improve the self-cleaning effect. It is conducive to avoiding compressor frequency reduction or shutdown, making the compressor perform better, and making the frosting effect more ideal during the self-cleaning process, improving the self-cleaning effect, and improving the user experience.

[0047] Optionally, the air conditioner controls the air conditioner to lower the exhaust temperature, including: the air conditioner controls the air conditioner to reduce the exhaust temperature by a temperature change value. In this way, if the outdoor ambient temperature is high, if the self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is higher than 4.8A, it is beneficial to better control the air conditioner to lower the exhaust temperature, so as to better release the load of the compressor, so as to better ensure that the compressor components are not damaged. It is beneficial to avoid compressor frequency reduction or shutdown, so that the compressor can play a better performance, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.

[0048] Optionally, the temperature change value can be 1°C. The temperature change value can be adjusted and set according to the properties of the air conditioner, which are not listed here one by one. In this way, if the outdoor ambient temperature is high, if self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is higher than 4.8A, the air conditioner is controlled to reduce the exhaust temperature by 1°C, which is conducive to better controlling the air conditioner to reduce the exhaust temperature, so as to better release the load of the compressor, so as to better ensure that the compressor components are not damaged. It is conducive to avoiding compressor frequency reduction or shutdown, making the compressor perform better, and making the frosting effect more ideal during the self-cleaning process, improving the self-cleaning effect, and improving the user experience.

[0049] Optionally, the air conditioner controls the air conditioner to increase the exhaust temperature, including: the air conditioner controls the air conditioner to increase the exhaust temperature by a temperature change value. In this way, if the outdoor ambient temperature is high, if the self-cleaning condensation and frosting are performed at this time, if the phase current of the compressor is low and is less than or equal to 4.8A, it is beneficial to better control the air conditioner to increase the exhaust temperature, and better perform frosting and condensation to improve the self-cleaning effect. It is beneficial to avoid compressor frequency reduction or shutdown, so that the compressor can play a better performance, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.

[0050] Optionally, the temperature change value can be 1°C.

It is beneficial to avoid compressor frequency reduction or shutdown, so that the compressor can perform better, and the frosting effect during the self-cleaning process is more ideal, thereby improving the self-cleaning effect and the user experience.

[0051] Optionally, the method also includes: there is a negative correlation between the opening of the throttle valve and the exhaust temperature. In this way, since there is a positive correlation between the compressor load and the phase current, and when the compressor frequency and the outdoor fan speed are the same, controlling the opening of the throttle valve will affect the compressor load. The smaller the throttle valve opening, the higher the exhaust temperature, and the larger the throttle valve opening, the lower the exhaust temperature. It is conducive to more accurately determining the relationship between the opening of the throttle valve and the exhaust temperature, so as to more accurately adjust the opening of the throttle valve and the exhaust temperature according to the phase current of the compressor, avoid compressor frequency reduction or shutdown, make the compressor perform better, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.

[0052] Optionally, there is a negative correlation between the opening of the throttle valve and the exhaust temperature, including: if the opening of the throttle valve increases the opening change value, the exhaust temperature decreases the temperature change value. If the opening of the throttle valve decreases the opening change value, the exhaust temperature increases the opening change value. In this way, since there is a positive correlation between the compressor load and the phase current, and when the compressor frequency is the same and the outdoor fan speed is the same, controlling the opening of the throttle valve will affect the compressor load. The smaller the throttle valve opening, the higher the exhaust temperature, and the larger the throttle valve opening, the lower the exhaust temperature. It is conducive to more accurately determine the relationship between the throttle valve opening and the exhaust temperature, so as to more accurately adjust the throttle valve opening and the exhaust temperature according to the phase current of the compressor, avoid compressor frequency reduction or shutdown, make the compressor perform better, and make the frosting effect more ideal during the self-cleaning process, improve the self-cleaning effect, and improve the user experience.
