WIPO Patent Application WO/2022/116611
Kind Code:
A1
Abstract:
A compressor return air dryness measurement method, an apparatus, a device, and a storage medium, belonging to the field of air conditioning technology. The method comprises: obtaining an exhaust air pressure, a return air pressure, an operating 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 according to the return air temperature and the return air saturation temperature; and when the temperature difference is less than a preset threshold, calculating a return air dryness of the compressor according to the exhaust air pressure, the return air pressure, the operating frequency, and the exhaust air temperature.
