<p>PROBLEM TO BE SOLVED: To realize an energy conservation type refrigerator effectively utilizing its waste heat which has heretofore discarded to a maximum limit, by assembling a water heater utilizing the heat energy with a heat from a compressor for compressing a refrigerant as a heat source. SOLUTION: A solenoid valve 15 is opened synchronously with an indoor cooling operation of a refrigerator compressor(CP) 10, and a circulating pump 13 is operated. Water is circulated to a pipe 12 and a water jacket 11, heated by heating of the CP 10, sent to a hot water storage tank 14 by a circulating pump 13, and is heated in the tank 14 to a warm water. When the CP 10 is stopped, the valve 15 is closed, the pump 13 is stopped, wafer flowing of the pipe 12 of the CP side is stopped, and the warm water of the tank 14 is used from a warm water supply port 17. When the water or warm water in the tank 14 is reduced, it is supplied from a water supply port 16, and an auxiliary heater 18 holds the warm water in the tank 14 at a predetermined temperature by supplying a current as needed. Thus, the discarded waste heat is recycled as it is, and the energy can be effectively utilized.</p> |
