<P>PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle which can maintain a good operation, and to provide a control valve suitable for the air conditioner for a vehicle. <P>SOLUTION: The air conditioner 1 for a vehicle includes a compressor 2, an outdoor heat exchanger 5, an indoor evaporator 7 and an auxiliary condenser 3. An overheat degree control valve 32 is disposed in a position downstream of the indoor heat exchanger 5 during a heating operation. The overheat degree control valve 32 includes: a body provided with an inlet port to introduce a refrigerant from the upstream, an outlet port to introduce the refrigerant to the downstream, and a main valve hole communicating the inlet port and the outlet port; a valve driving body including a main valve element that contacts or detaches from the valve hole to adjust a valve open degree; and a temperature sensing part that senses the temperature and pressure of the refrigerant flowing in an inner passage connecting the inlet port and the outlet port, and drives to open or close the main valve element to control the overheat degree of the refrigerant to a set degree. <P>COPYRIGHT: (C)2012,JPO&INPIT |
