WIPO Patent Application WO/2016/187939
Kind Code:
A1
Abstract:
A frequency control method for a variable frequency compressor of a heat pump hot water machine. The method comprises: detecting the outlet water temperature of a heat exchanger and the water tank temperature (T5) of a water tank (40); generating an outlet water set temperature (T1S) of the heat exchanger according to the water tank temperature (T5); and controlling the frequency of the variable frequency compressor (10) according to the outlet water temperature and the outlet water set temperature (T1S) of the heat exchanger. In addition, a frequency control system for the variable frequency compressor of the heat pump hot water machine is also related to.
