を特徴とする車輌用冷房装置。 a rotational speed detection means for detecting the rotational speed of either the engine or the compressor; a temperature detection means for detecting the temperature inside or outside the vehicle which is set according to the season; and the compressor. an on-off valve provided in the suction port of the inlet port for opening and closing the suction port, and a control unit that outputs an operating signal to the on-off valve based on each detection signal from the rotation detection means and the temperature detection means, The control unit performs a calculation to change a predetermined value of the rotational speed for switching the open/close valve of the compressor in response to the temperature detected by the temperature detection means, and the rotational speed reaches the changed predetermined value. In some cases, the on-off valve operates in a direction to close the suction port based on a detection signal from the rotational speed detection means and an output signal from the control unit to change the refrigerant discharge capacity of the compressor. Characteristic vehicle cooling system.
