Abstract

The application discloses a heat dissipation control method and device of a compressor, the compressor and a storage medium, and the method comprises the following steps: after starting the compressor, the temperature of a power module of a frequency converter is acquired and is recorded as the temperature of the frequency converter; the winding temperature of a motor is acquired and is recorded as the temperature of the motor; and the load current of the compressor is acquired; according to the temperature of the frequency converter and the load current of the compressor, the opening and closing of a first electromagnetic valve is controlled to realize heat dissipation control of the power module of the frequency converter; and according to the temperature of the motor and the load current of the compressor, the opening and closing of a second electromagnetic valve is controlled to realize heat dissipation control of the winding of the motor. According to the scheme, low-temperature and low-pressure refrigerant is introduced into the compressor to perform heat exchange and cooling, the flow of the refrigerant inlet is periodically controlled by the electromagnetic valve according to the temperature of the compressor, the power module of the frequency converter and the compressor are protected, and the operation reliability and safety of the compressor are improved.
