Abstract

A method and a device for controlling a compressor to stop are disclosed in the present disclosure. The method includes: acquiring a rotor phase corresponding to a minimum load of the compressor; during a shutdown process of the air conditioner, acquiring a current orientation of the rotor of the compressor and determining whether a phase of the rotor is the rotor phase corresponding to the minimum load according to the current orientation of the rotor; and controlling the compressor to stop if determining that the phase of the rotor is the rotor phase corresponding to the minimum load. Therefore, a generated vibration and stress of a piping is smaller than that generated by directly stopping the compressor, to effectively reduce the vibration and stress of the piping at the moment that the compressor is stopped and to avoid a danger of breaking the piping.
