<P>PROBLEM TO BE SOLVED: To provide an flash water-heater type heat-pump type water heater capable of heating water with excellent responsiveness and temperature control accuracy. <P>SOLUTION: This flash water-heater type heat pump type water heater is provided with a heat exchanger 10 having a water flow passage 9 to exchange the heat between a refrigerant flow passage 8 of a radiator 3 in a heat pump cycle 7, a water supply pipe 11 for supplying the water of water service to the water passage 9, and a hot-water supply circuit 13 connected to supply the water from the water flow passage 9 to a hot-water supply terminal such as a shower 16 and a faucet 17. The hot-water supply circuit 13 has a mixing means 20 for mixing the water of water service, and the mixing means is operated to mix the water in the hot-water heated by the heat exchanger to lower temperature for the temperature control. Even if the heat pump cycle is operated in the high heating ability condition, quick and accurate correspondence to a sudden change of a target temperature is possible. <P>COPYRIGHT: (C)2004,JPO |
