COMPRESSOR RETURN AIR DRYNESS MEASUREMENT METHOD, APPARATUS, DEVICE, AND STORAGE MEDIUM

In the technical field of air conditioning, a compressor return air dryness detection method, apparatus, and device, and a storage medium are provided. The 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 calculating, in response to the temperature difference value being smaller than a predetermined threshold value, 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.
