Abstract:
1. An air conditioner for a vehicle, comprising: a cooling heat exchanger which cools air to be blown into a compartment of the vehicle; a temperature detecting unit for detecting a temperature of air immediately after being cooled in the cooling heat exchanger; a variable displacement compressor driven by an engine of the vehicle to compress refrigerant after passing through the cooling heat exchanger and to discharge the compressed refrigerant in a refrigerant cycle; a deceleration detecting unit for detecting a deceleration running state of the vehicle; and a control unit which calculates a target cooling temperature of air to be cooled by the cooling heat exchanger, and controls a discharge capacity of the compressor such that the temperature detected by the temperature detecting unit approaches the target cooling temperature, wherein: the control unit includes a dry determination means for determining whether a surface of the cooling heat exchanger on an air side is dry; when the deceleration detecting unit detects the deceleration running state of the vehicle, the control unit controls the discharge capacity of the compressor approximately at a maximum capacity, regardless of the target cooling temperature; and when the dry determination means determines that the surface of the cooling heat exchanger is dry, the control unit controls the discharge capacity of the compressor such that the temperature detected by the temperature detecting unit approaches the target cooling temperature, regardless of a detection result of the deceleration detecting unit.
