<P>PROBLEM TO BE SOLVED: To provide a hot water supply system for hot water supply and heating capable of being miniaturized by increasing energy density in supplying hot water. <P>SOLUTION: This hot water supply system comprises a water circulating passage 120 connected to a water use-side passage 110, a water supply passage 100 for supplying the water to the water circulating passage 120, and a refrigerating cycle 200 exchanging heat between the water in the water circulating passage 120 and a refrigerant by a water-refrigerant heat exchanger 210, and a pressure of the water in the water circulating passage 120 is higher than a pressure of the water in the water supply passage 100 in performing the heat exchange by the water-refrigerant heat exchanger 210. <P>COPYRIGHT: (C)2009,JPO&INPIT |
