PROBLEM TO BE SOLVED: To provide a CO<SB>2</SB>cycle driving device using solar power generation solving a further problem of environmental destruction, usable without trouble even in an area with an unstable electric power situation, and capable of efficiently utilizing energy. SOLUTION: The C0<SB>2</SB>cycle driving device using solar power generation comprises a refrigerant circuit formed by annularly connecting a compressor 10, a gas cooler 154, an expansion valve 156, an evaporator 157, and the like, using carbon dioxide as a refrigerant, and allowing the high pressure side to have supercritical pressure; a solar battery SD; and a water storage tank 176. Electric power generated in the solar battery SD is applied to an electric element 14 to carry out operation. The water storage tank 176 is divided to a warm water chamber 177 and a cold water chamber 178. Water in the warm water chamber 177 is heated by the gas cooler 154, and water in the cold water chamber 178 is cooled by the evaporator 157. COPYRIGHT: (C)2007,JPO&INPIT
