<P>PROBLEM TO BE SOLVED: To provide a hot water circulation type hot water supply system capable of decomposing and removing organic substances such as sebum existing in hot water as impurities, and sterilizing pathogenic bacteria without generating chlorine smell. <P>SOLUTION: An electrolytic cleaning device 10 is disposed at an upstream side with respect to a filtering device 11 of a hot water circulation cycle 14, a hot water heating sterilizing device 11 is disposed at a downstream side of the filtering device 11, the hot water passing through the electrolytic cleaning device 10 is electrically decomposed to generate active oxygen, the organic substances in the hot water are oxidized and decomposed by using active oxygen, and heat exchange is performed between a refrigerant heated by a refrigerant circulation cycle 23 and hot water in the hot water heating sterilizing device 11, thus the sterilizing treatment can be performed without injecting chlorine antiseptic liquid to the hot water. <P>COPYRIGHT: (C)2008,JPO&INPIT |
