Abstract: The present disclosure provides a control method, apparatus, and device for a compressor, a storage medium, and a refrigerator system. The control method includes: obtaining an electrical parameter, a return air parameter, and a first frequency of the compressor during operation of the compressor; determining a first fitting formula corresponding to the first frequency; obtaining an exhaust pressure by inputting the electrical parameter and the return air parameter into the first fitting formula for calculation; and controlling the compressor based on the exhaust pressure. In this way, the pressure sensor disposed on an exhaust side of an air conditioner can be omitted, hence cost is saved; or for the air conditioner with the pressure sensor on the exhaust side, the above manner for calculation can be an alternative to obtaining the exhaust pressure, which ensures a user's normal use and thus improves the user experience.

Abstract: 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.
