Abstract (en)
[origin: EP3306219A1] A heat pump hot-water supply system includes a heat pump water heater (100) including a main circuit (80), in which a compressor (1) configured to compress refrigerant, a gas cooler (2), a first solenoid valve (80V1), a regenerative heat exchanger (3), an expansion valve (4), and an air heat exchanger (5) are connected in the stated order, a hot-water supply tank (20) including a heat medium for exchanging heat with the refrigerant flowing through the gas cooler (2), and a heat storage tank (30) including a heat medium for exchanging heat with the refrigerant flowing through the regenerative heat exchanger (3). The heat pump water heater (100) includes a first bypass (81) formed to branch off the main circuit (80) at a first branching portion (81 a) located on an outlet side of the gas cooler (2) and an inlet side of the first solenoid valve (80V1), and to merge with the main circuit (80) at a first merging portion (81 b) located on an outlet side of the regenerative heat exchanger (3) and an inlet side of the expansion valve (4); and a control unit (50) configured to switch the first solenoid valve (80V1) to be opened or closed.
