A compressor return air dryness detection method includes: obtaining an exhaust air pressure, a return air pressure, a working frequency, an exhaust air temperature, and a return air temperature of a compressor; determining a return air saturation temperature corresponding to the return air pressure; calculating a temperature difference value based on the return air temperature and the return air saturation temperature; and in accordance with a determination that the temperature difference value is smaller than a predetermined threshold value, calculating a return air dryness of the compressor based on the exhaust air pressure, the return air pressure, the working frequency, and the exhaust air temperature.

Temperature adjustment device, control method therefor, control apparatus thereof, and storage medium

The present disclosure discloses an air conditioner controlling method and apparatus, as well as an air conditioner having the same. The method includes: determining that an outdoor heat exchanger of the air conditioner runs in an evaporator state; acquiring a state signal of a refrigerant of an indoor refrigerating unit; and adjusting an opening degree of an electronic expansion valve of an outdoor unit according to the state signal of the indoor refrigerating unit. This method may adjust the opening degree of the electronic expansion valve of the outdoor unit according to the state signal of the indoor refrigerating unit when the outdoor heat exchanger of the air conditioner runs in the evaporator state, thereby effectively improving the reliability of control, broadening the reliable operation range of the system, and reasonably distributing the refrigerant between the indoor refrigerating unit and the outdoor unit under a low temperature working condition.
