A controlled compressor apparatus enables a hybrid compressor in an idle-stopping vehicle to operate more efficiently when driven by a motor alone. The controlled compressor apparatus includes a compressor 110, included in a refrigeration circuit 200, of a variable volume type for compressing a refrigerant; a motor 120 powered by a battery 12 to operate; and a controller 130 for selecting the driving force provided either by the engine 10 or the motor 120 to drive the compressor 110 and control its discharge volume. The controller 130 causes the motor 120 to operate the compressor 110 such that the compressor 110 is turned on or off at a discharge volume of the compressor 110 that larger within a variable range than that required for operating the refrigeration circuit 200.
