Title: AIR CONDITIONER, AND SHUTDOWN CONTROL METHOD AND DEVICE FOR COMPRESSOR THEREOF
Abstract:
An air conditioner, and a shutdown control method and device for a compressor thereof. The method comprises the following steps: during the shutdown process of an air conditioner, when receiving a compressor shutdown signal, controlling a driving circuit (10) of the compressor so that three-phase windings of the compressor are shorted; and controlling a rotor brake of the compressor according to a brake torque generated when the three-phase windings of the compressor are shorted, so that the compressor stops running. The method controls the driving circuit of a compressor so that the three-phase windings of the compressor are shorted to generate a brake torque and accelerate the rotor brake of the compressor, such that the compressor can quickly be braked and static, facilitating reduction of the pipe stress of an air conditioner, and improving the service life of the pipes in the air conditioner.
