LOW-ENERGY-CONSUMPTION CONTROL METHOD FOR HEAT PUMP LOW-TEMPERATURE DRYER, ELECTRONIC DEVICE AND STORAGE MEDIUM

Provided are a low-energy-consumption control method for a heat pump low-temperature dryer, an electronic device, and a storage medium, belonging to the technical field of heat pump control. The present method, by means of controlling a compressor operating point and dehumidification performance of an evaporator, can achieve the goal of reducing overall device energy consumption. In a heat pump unit, the compressor, a condenser, an expansion valve and the evaporator are connected in sequence to form a refrigeration circulation loop; the compressor operating point comprises evaporation temperature and condensation temperature. First, an operating point with a COP value larger than a set value when preset evaporation temperature and condensation temperatures are satisfied is selected as an optimal operating point for the compressor. Then, structural design of the heat exchanger is conducted, so that a heat exchange volume of the heat exchanger can satisfy the requirement that the compressor operates at the opti
