CONTROL DEVICE OF AIR CONDITIONER FOR ELECTRIC VEHICLE

PURPOSE:To improve capacity of heating operation by opening a passage to a main condenser and a bypass passage directly after stopping a compressor so as to improve restartability of the compressor, and thereafter closing the passage to the main condenser. CONSTITUTION:In this air conditioner 1, an evaporator 8 and a sub-condenser 9 are arranged inside an air conditioning duct 2. A compressor 22, a main condenser 24, the sub-condenser 9, an expansion valve 21, and the evaporator 8 are in order connected together so as to form a cooling cycle, and the main condenser 24 is bypassed so as to form a heating cycle. In this case, a passage between the compressor 22 and the main condenser 24 is opened with a first valve 23, a passage 27 bypassing the main condenser 24 is closed with a second valve 26. During a prescribed time after stopping the cooling or heating cycle, both valves 23, 26 are respectively opened. Meanwhile, after the lapse of the prescribed time after stopping, the first valve 23 is closed and the second valve 26 is opened.
