Abstract
A displacement control system (A) of a variable displacement compressor sets a target for pressure in an intake chamber or a crank chamber, on the basis of a detected evaporator-outlet air temperature and a target for evaporator-outlet air temperature. The pressure of a refrigerant in a high-pressure section is detected, and a regulating current is supplied to a solenoid () of a displacement control valve, on the basis of the pressure of the refrigerant in the high-pressure section and the target for pressure.
