Title:
HEAT PUMP-TYPE WATER HEATER
Document Type and Number:
WIPO Patent Application WO/2012/121382
Kind Code:
A1
Abstract:
The purpose of this invention is improved energy efficiency. This heat pump-type water heater (1) is provided with a heat pump unit (2) having a refrigerant circuit (3) in which a refrigerant compressed in a condenser (22) is circulated, and a hot water storage tank (5) for storing hot water heated in the condenser (22). This heat pump-type water heater can adopt a circulation boiling mode in which a first flow amount of heated water is supplied to the hot water storage tank, and a transient boiling mode in which a second flow amount of heated water greater than the first flow amount is supplied to the top side of the hot water storage tank (5), and said heat pump-type water heater switches between the circulation boiling mode and the transient boiling mode on the basis of the temperature of the refrigerant supplied to the condenser (22).
