摘要： An automotive air conditioner (1) includes a compressor (2), an external heat exchanger (5), an evaporator, and an auxiliary condenser (3). The external heat exchanger (5) functions as an external condenser during a cooling operation and also functions as an external evaporator during a heating operation. A first expansion valve (41) is provided in a first refrigerant circulation passage through which the refrigerant discharged from the compressor (2) is able to circulate by passing sequentially through the external heat exchanger (5) and the evaporator and returning to the compressor (2). A second expansion valve (42) is provided in a second refrigerant circulation passage through which the refrigerant discharged from the compressor (2) is able to circulate by passing sequentially through the auxiliary condenser (3) and the external heat exchanger (5) and returning to the compressor (2). The second expansion valve (42) regulates the valve opening degree such that the refrigerant state at an inlet side of the compressor (2) during a heating operation is in a range where the dryness of refrigerant is greater than or equal to 0.9 and the superheat of refrigerant is less than or equal to 5°C.

摘要： A control valve according to one embodiment includes a body having a main passage communicating a discharge chamber with a crankcase and a sub-passage communicating the crankcase with a suction chamber, a main valve provided in the main valve passage, a sub-valve provided in the sub-passage, a power element for receiving the suction pressure of the suction chamber and generating a drive force exerted in an opening direction of the main valve in accordance with the magnitude of the suction pressure, and a solenoid for generating a drive force in a closing direction of the main valve in accordance with the amount of current supplied. The control valve is configured such that the sub-valve remains closed when the main valve is controlled and such that the sub-valve is opened after the main valve is closed. Also, a change in the area of opening of the sub-valve relative to the uplift amount of the sub-valve element from the sub-valve seat is larger than that of the main valve relative to the uplift amount of the main valve element from the main valve seat.

A valve-opening mechanism used to open the sub-valve by using the drive force of the solenoid is further included. The outside diameter of the body becomes smaller toward the pressure-sensing section side from the solenoid side. The pressure-sensing section, the main valve, the sub-valve, and the solenoid are arranged in this order from one end side of the body. The sub-valve is provided on a side closer to the solenoid where the outside diameter of the body is larger.
