HOT-WATER FEEDER UTILIZING SOLAR HEAT

PURPOSE:To improve the efficiency of water supply system, by organizing a heat collecting circuit successively connecting a compressor for compressing a refrigerant of an application medium, a heat pipe of a condenser for radiating application, a pressure reduction device with an expansion valve, a heat collector for absorbing solar heat and vaporizing a refrigerant, and a vapor/liquid separator. CONSTITUTION:A refrigerant vaporized absorbing solar heat and air heat through a heat collector 3 is put at high tension and temperature through a vapor/liquid separator 11 and by a compressor 5, and is condensed and liquidized by adding heat to a liquid refrigerant of low temperature in a heat pipe 10. Then, the refrigerant is fed to the heat collector 3 in a state of low tension liquid which is easily pressure-reduced and vaporized by an expansion valve 7, and the circulating refrigerant circuit for collecting heat is formed. The liquid refrigerant in the heat pipe 10 is gasified to be transferred into a regenerative tank 9 and heats water in the tank 9 exchanging heat in cycles of being condensed and liquidized by radiating the water the tank 9.
