PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of securing window clearness by interlocking heat radiation of a radiator and outside air introduction and preventing wasteful exhausting of heat.SOLUTION: An air conditioner includes: a first circulating cycle 1 circulating a first heat medium in order of a compressor 5, a heat exchanger 6, an expansion device 7, an evaporator 8 and the compressor 5; a second circulating cycle 2 circulating a second heat medium in order of a pump 10, the heat exchanger 6, a heater core 11 and the pump 10 and including a radiator 12, a bypass flow passage 13 and a flow rate adjusting valve 14 for adjusting flow rate of the radiator 12 and the bypass flow passage 13; and an air conditioning unit 4 in which an intake device 31, an evaporator 8 and the heater core 11 are disposed in an air blow passage 3. The heat exchanger 6 moves heat of the first heat medium to the second heat medium. The intake device 31 relatively increases an outside air introduction rate when a temperature of the second heat medium exceeds a first prescribed temperature. The flow rate adjusting valve 14 flows the second heat medium to the radiator 12 when a temperature of the second heat medium exceeds a second prescribed temperature higher than the first prescribed temperature. |
