Title:
HEAT PUMP HEAT SOURCE DEVICE AND HEAT PUMP WATER HEATER
Document Type and Number:
WIPO Patent Application WO/2021/191949
Kind Code:
A1
Abstract:
According to one embodiment, this heat pump water heater comprises a compressor, a water heat exchanger, a tank, a water radiator, a pump, a heater, a first temperature sensor, a second temperature sensor, and a control unit. The first temperature sensor detects the first temperature of water from which heat dissipates into the water stored in the tank and which flows into the flow path of the water heat exchanger. The second temperature sensor detects the second temperature of the water stored in the tank. The control unit controls the running or stopping of the compressor on the basis of the first temperature and the second temperature, and also controls the rotational speed of the compressor on the basis of the first temperature when the compressor is run.
