<P>PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of effectively using the quantity of heat that each of plural kinds of fluids has by realizing proper heat exchange of the plural kinds of fluids by a composite heat exchanger. <P>SOLUTION: The composite heat exchanger 13 includes a first heat exchanger 131, which exchanges heat between a refrigerant and blown air, and a second heat exchanger 132, which exchanges heat between the coolant of an engine EG and the blown air. The composite heat exchanger is integrated to enable heat transfer between the discharged refrigerant flowing in the first heat exchanger 131 and the coolant flowing in the second heat exchanger 132. By adjusting at least one of refrigerant discharging capacity of a compressor 11 which discharges the refrigerant that flows into the first heat exchanger 131, inflow quantity of the coolant into the second heat exchanger 132, and quantity of blown air sent to the composite heat exchanger 13 of the composite heat exchanger 13, the proper heat exchange is realized among the blown air, discharged refrigerant, and coolant in the composite heat exchanger 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
