<P>PROBLEM TO BE SOLVED: To provide a hot water supply system using a natural coolant capable of improving efficiency and capable of lowering operation pressure. <P>SOLUTION: This hot water supply system is provided with a CO<SB>2</SB>cycle using carbon dioxide, a water side evaporator for evaporating water of which the pressure is lower than the atmospheric pressure by waste heat from a condenser of the CO<SB>2</SB>cycle, a water side compressor for sucking and compressing vapor evaporated in the water side evaporator so as to deliver high temperature vapor, and a water circuit for heating city water by the high temperature vapor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
