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

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

[0036] By using the method for self-cleaning of the air conditioner provided in the embodiments of the present disclosure, in the case of extreme working conditions such as high outdoor environment temperature during the self-cleaning process of the air conditioner, the opening degree of the throttling valve and the exhaust temperature are adjusted according to the phase current of the compressor, so as to avoid the compressor to reduce frequency or stop, make the compressor to have better performance, and make the frosting effect in the self-cleaning process more ideal, improve the self-cleaning effect, and improve the user experience.

[0037] Optionally, the air conditioner controls the air conditioner to adjust the opening degree of the throttling valve and the exhaust temperature according to the phase current of the compressor, comprising: the air conditioner controls the air conditioner to adjust the opening degree of the throttling valve and the exhaust temperature according to the outdoor environment temperature and the phase current of the compressor. In this way, if the outdoor environment temperature is high, the opening degree of the throttling valve and the exhaust temperature are adjusted according to the phase current of the compressor and the outdoor environment temperature, so as to avoid the compressor to reduce frequency or stop, make the compressor to have better performance, and make the frosting effect in the self-cleaning process more ideal, improve the self-cleaning effect, and improve the user experience.

[0038] Optionally, the air conditioner controls the opening degree of the throttling valve and the exhaust temperature of the air conditioner according to the outdoor environment temperature and the phase current of the compressor, and the method comprises: in the case that the outdoor environment temperature meets the extreme working condition, the air conditioner determines the size relationship between the phase current of the compressor and the phase current threshold value. According to the size relationship between the phase current of the compressor and the phase current threshold value, the air conditioner controls the opening degree of the throttling valve and the exhaust temperature of the air conditioner. In this way, if the outdoor environment temperature is high, the opening degree of the throttling valve and the exhaust temperature are adjusted according to the phase current of the compressor after it is determined whether the outdoor environment temperature meets the extreme working condition, so as to avoid the frequency reduction or shutdown of the compressor, make the compressor have better performance, make the frosting effect more ideal in the self-cleaning process, improve the self-cleaning effect, and improve the user experience.
