Title:
WATER TEMPERATURE CONTROL METHOD FOR HEAT PUMP SYSTEM, AND HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/082202
Kind Code:
A1
Abstract:
A water temperature control method for a heat pump system, and a heat pump system. The method comprises: measuring the current outlet water temperature of a device end in real time, and obtaining the current outlet water temperature difference between the current outlet water temperature and a set outlet water temperature; and determining the current compressor energy level gear according to the current outlet water temperature difference, obtaining the current compressor frequency corresponding to the current compressor energy level gear in a preset energy level gear table, and controlling a variable frequency compressor using the current compressor frequency. The system can achieve self-adaption of a device to a change in the load of an end and achieve dynamic adjustment of the outlet water temperature after the change in the end occurs to keep the water temperature constant, thereby improving the performance of a primary heat pump system.
