PROBLEM TO BE SOLVED: To supplement the lowering of a heat efficiency when a heat exchange is performed between an absorption side heat exchanger and a radiating side heat exchanger through an intermediate heat medium. SOLUTION: A coolant circulating route 3 is formed between a cooling unit 1 as the absorption side heat exchanger and an air-cooled condenser 2 as the radiating side heat exchanger, and the cooling unit 1 is connected to the air- cooled condenser 2 so as to be heat-exchanged. The heat medium for the cooling unit 1 is, for example, freon which is cooled by the coolant in the circulating route 3. The coolant is cooled by the air-cooled condenser 2. A circulation pump 4 and a one-way valve 5 as a coolant pressurizing means are disposed on the high temperature side of the circulating route 3, and a gas sealing valve 6 and a flow restricting valve 7 as a coolant depressuring means are disposed on the low temperature side. Also, a tank 8 for saturated gas balance is installed for the gas sealing valve 6. Extra gas for preventing a saturated concentration of gas from being varied even if a coolant temperature is varied slightly is accumulated in the tank 8. COPYRIGHT: (C)2004,JPO
