<P>PROBLEM TO BE SOLVED: To provide a heat pump type hot water supply facility with a heat exchanger for reheating bathtub water which can reheat the bathtub water by circulating a bathing water of the bathtub to a secondary side of the exchanger for reheating, circulating a high temperature water in a hot water storage tank, and preventing the temperature of the high temperature water in the tank from decreasing. <P>SOLUTION: The heat pump type hot water supply facility 10 passes a refrigerant becoming a high temperature by being pressurized by a heat pump unit 11 through a primary side 14 of a high temperature side heat exchanger 15, returns the high temperature water obtained by passing the water supplied from the lower part of the hot water storage tank 20 through the secondary side 19 of the exchanger 15 to the upper part of the tank 20 and storing the water, and supplies the water as a bathing water to the bathtub 32 as needed. The heat exchanger 46 is provided for reheating the bathing water in the bathtub 32 by circulating the water to the secondary side, the high temperature water from the upper part of the tank 20 is introduced to the primary side of the exchanger 46, and a warm water after heat exchanging at the primary side is returned to the secondary side 19 of the exchanger 15. <P>COPYRIGHT: (C)2004,JPO |
