摘要： An apparatus for controlling a displacement changing unit of a variable displacement type refrigerant compressor arranged in a car air-conditioner circuit, including a refrigerant evaporator for cooling air for air-conditioning a compartment of a car, is provided with a temperature detecting device for detecting an actual temperature of the air for air-conditioning the car compartment, a temperature setting switch for setting a desired temperature of the air for air-conditioning the car compartment, a unit for generating an electric signal indicating a change in an operating condition of the air blowing fan of the refrigerant evaporator, a control unit for carrying out a PID control to control the operation of the displacement changing unit of the compressor in response to a difference between the actual and desired temperatures and a signal of a unit for generating an electric signal indicating a change in the operating condition of the air blowing fan, to thereby eliminate the difference between the desired and actual air temperatures while suppressing hunting which causes a change in the actual temperature of the air, for air-conditioning the car compartment during the control operation of the control unit.
