<P>PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle, which respectively sets a heating medium to the optimal temperature for air-conditioning in a cabin and for cooling of an on-vehicle heating element. <P>SOLUTION: This air conditioner for the vehicle includes a refrigerant circulating passage 90 of a refrigerating cycle of annularly connecting a refrigerant 40 and an air-conditioning heat exchange circuit 91A for exchanging heat with introducing air in the cabin, and a heat exchange circuit 91B for an apparatus connected in parallel to the air-conditioning heat exchange circuit 91A and exchanging heat between the refrigerant 40 and an on-vehicle apparatus 9. The heat exchange circuit 91B for the apparatus includes a cooling heating medium circulating passage 91B different from the refrigerating cycle refrigerant circulating passage 90, and this cooling heating medium circulating passage 91B is provided with a cooling heat exchanger 4B for exchanging heat between the refrigerant 40 of the refrigerating cycle refrigerant circulating passage 90 and a cooling heating medium 41B for cooling the on-vehicle apparatus 9, and a cooling circulating pump 5B for circulating the cooling heating medium 41B between the on-vehicle apparatus 9 and the cooling heat exchanger 4B. <P>COPYRIGHT: (C)2011,JPO&INPIT |
