HEAT PUMP DEFROSTING CONTROL METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM

The present invention relates to the field of heat pump technologies, and discloses a heat pump defrosting control method, apparatus, and device, and a storage medium. The heat pump defrosting control method includes: reading in real time flag bit values respectively corresponding to multiple defrosting determining parameters; determining, according to each read flag bit value, whether a current heat pump meets a defrosting entry condition; if the current heat pump meets the defrosting entry condition, entering a heat pump defrosting time sequence; after the heat pump defrosting time sequence is entered, detecting compressor discharge pressure and compressor suction pressure at preset interval duration, and calculating a pressure difference between the compressor discharge pressure and the compressor suction pressure; and dynamically adjusting operation manners of a compressor, a fan, and an electronic expansion valve according to the pressure difference in the heat pump defrosting time sequence. In the present invention, by controlling a defrosting entry opportunity and a defrosting process, noise in the defrosting process is greatly reduced, and work efficiency of a heat pump is also improved.
