Air conditioner for vehicle


An air conditioner for a vehicle includes: a compressor that compresses refrigerant for conditioning air in a vehicle cabin and defines a refrigeration cycle; a detecting section that detects a thermal load of air-conditioning in the vehicle cabin; and a control section that controls a rotational speed of the compressor such that the thermal load detected by the detecting section satisfies a predetermined air conditioning request in the vehicle cabin. In case where the air conditioning request is satisfied by controlling the rotational speed of the compressor, the control section periodically switches between a reference rotational speed and a low rotational speed that is lower than the reference rotational speed in order to maintain a state where the air conditioning request is satisfied.
