PROBLEM TO BE SOLVED: To reduce the cost and operation expenses by connecting an exhaust gas heat exchanger to a radiator via heat transfer means sealing heating medium, thereby giving the exhaust heat of the engine to refrigerant without requiring any power and discontinuing engine cooling water circulating system. SOLUTION: When the exhaust gas of an engine flows through an exhaust gas heat exchanger 22, it heats the evaporator 24A of heat transfer means 24. The liquid-like heating medium in the evaporator 24A of the means 24 is heated, evaporated, and the vapor is introduced to a condenser 24B disposed in a radiator 23 through the means 24, heat exchanged with the atmosphere supplied by an outdoor fan 7, condensed to be liquefied. The liquid-like heating medium is returned to the evaporator 24A through the means 24, and this is repeated. The heat of the exhaust gas of the engine is transmitted to the heating medium of the means 24 via the exchanger 22, and transferred to the radiator 23 by the movement of the medium. |
