WIPO Patent Application WO/2019/163099
Kind Code:
A1
Abstract:
This hot water supply device has: a heat pump device to which a compressor and a heat exchanger are connected; a heat medium circuit connected to the heat pump device with the heat exchanger therebetween; a tank for collecting water that has exchanged heat with the heat medium of the heat medium circuit; two tank temperature detecting means which are attached to respective locations at different heights of the tank and detect the temperature of water inside the tank; and a control unit which controls the temperature of the water inside the tank using the values detected by the two tank temperature detecting means. The control unit sets a target hot water supply temperature of the water inside the tank on the basis of: a hot water storage temperature indicated by the value detected by one of the two tank temperature detecting means; and a tank internal temperature difference which is the difference between the respective tank internal temperatures detected by the two tank temperature detecting means.
