輌用冷房装置。 A vehicle cooling system is provided with an engine-driven compressor that stops operating by releasing an electromagnetic clutch when the temperature of air discharged into the vehicle interior falls below a predetermined cooling temperature, the rotation of the compressor The compressor has a detection means for detecting the speed, an on-off valve provided at a suction port of the compressor to open and close the suction port, and a control unit that outputs a signal to the on-off valve based on a signal from the detection means. , when the rotational speed of the compressor reaches a predetermined value or higher, a detection signal from the detection means is controlled by the control unit, and the on-off valve is operated in a direction to close the suction port by this control signal. . A vehicle cooling system, wherein the refrigerant discharge capacity of the compressor changes.
