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

Embodiments provide a temperature adjusting device, an air conditioning system, a control method, and a readable storage medium. The temperature adjusting device includes: an evaporative cooling device, having an indoor air supply port and an outdoor air outlet; and a compressor device, including a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger, a first throttling component, a second throttling component, and a reversing valve. The first heat exchanger exchanges heat with indoor air at the indoor air supply port and recovers waste heat, the second heat exchanger exchanges heat with outdoor air at the outdoor air outlet and recovers waste heat, and a refrigerant discharged by the compressor exchanges heat with a heat exchange medium in the third heat exchanger.
