Title:
WATER TEMPERATURE CONTROL METHOD FOR SWIMMING POOL HEAT PUMP SYSTEM, APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/155940
Kind Code:
A1
Abstract:
The invention relates to the technical field of heat pumps. Disclosed are a water temperature control method for a swimming pool heat pump system, an apparatus, a device, and a storage medium, for use in adjusting the water temperature of a swimming pool on the basis of the temperature of the external environment, increasing the coefficient of performance of the swimming pool heat pump system when working, reducing energy consumption, and preventing the swimming pool heat pump system from being turned on and off frequently, thus increasing the service life of the swimming pool heat pump system. The method of the present invention comprises: acquiring the temperature of the external environment and adjusting a heating temperature on the basis of the temperature of the external environment to produce a target heating temperature; detecting the temperature of intake water of a swimming pool heat pump system and determining the absolute value of the temperature difference between the temperature of the intake water and the target heating temperature; determining a target operating frequency band for the swimming pool heat pump system on the basis of the absolute value of the temperature difference, controlling a variable-frequency compressor in the swimming pool heat pump system to heat, on the basis of the target operating frequency band, water in a container to be heated, and introducing the heated water in said container as replacement into a swimming pool via a circulating pump.
