<P>PROBLEM TO BE SOLVED: To provide an engine-driven type air conditioner which can suitably secure the temperature of exhaust gas, without reducing cooling performance of an engine. <P>SOLUTION: An exhaust passage 40 has first and second exhaust flow passages 43 and 44 of parallel connection, and discharges the exhaust gas exhausted from the engine 10 to the atmosphere. The engine-driven type air conditioner includes an exhaust heat exchanger 45 arranged in one (the first exhaust flow passage 43) of the first and second exhaust flow passages 43 and 44 and warming a coolant by the exhaust gas in heating operation, a sub-heat exchanger 18 for warming a refrigerant by the coolant in the heating operation and functioning as an evaporator of the refrigerant, a temperature sensor 48 for detecting the temperature of the exhaust gas of an exhaust passage 40 on the upstream side of the first and second exhaust flow passages 43 and 44, and a switching valve 47 arranged in the exhaust passage 40 and adjusting the flow rate distribution of the exhaust gas respectively flowing in the first and second exhaust flow passages 43 and 44 so that the detected exhaust gas temperature exceeds the preset temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
