Document Type and Number:
WIPO Patent Application WO/2023/138094
Kind Code:
A1
Abstract:
The present invention relates to the field of intelligent household appliances, and provides a method for air conditioner self-cleaning. The method comprises: determining a temperature difference K between an evaporator coil and an evaporator fin; and adjusting a frequency and an exhaust temperature of a compressor according to K, such that K is in a first preset temperature difference range. According to the method, during the air conditioner self-cleaning process, the frequency and the exhaust temperature of the compressor are adjusted according to the temperature difference K between the evaporator coil and the evaporator fin, which prevents a fast temperature drop or rise in the refrigerant of the evaporator, thus keeping the temperature difference between the evaporator coil and the evaporator fin in the first preset temperature difference range and avoiding thermal expansion voice due to remarkable temperature difference between the evaporator coil and the evaporator fin. The present invention further discloses an apparatus for air conditioner self-cleaning and an air conditioner.
