摘要： 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, i.e., a physical pressure sensor on the exhaust side is not needed, hence cost is saved; or for the air conditioner with the pressure sensor on the exhaust side, when the pressure sensor on the exhaust side is damaged, 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.
