摘要：A hot-water supply system heats water through heat exchange between high-temperature refrigerant of a heat pump circuit and water of a water circulating circuit.

The system is an instantaneous water heater unit for instantaneously heating, at a waterheat exchanger, water supplied through a water supply pipe and supplying hot water to ausing end unit. Therefore, a large-capacity hot-water storage tank is not needed.Sufficient heat of condensation to heat water can not be produced, because pressureconditions of the heat pump circuit is not stabilized just after the start of operation.Therefore, during a short period of rising time, hot water stored in a hot-water supplytank and water from the water heat exchanger are mixed and the mixture is supplied tokeep the hot water at a preset temperature. Therefore, it is possible to use a smallerhot-water supply tank.
