摘要： PROBLEM TO BE SOLVED: To provide a vehicular air conditioner capable of achieving power-saving of a compressor by controlling the compressor so that a temperature of an evaporator is kept rather high rather than lowering it to a limit temperature whereby no frost is caused, and a temperature of air actually blown out to a vehicle interior becomes the most suitable target temperature in response to the condition at that time. SOLUTION: This vehicular air conditioner is equipped with a ventilation duct having a blow-off outlet in the vehicle interior, a heat exchanger provided in the duct and connected to a variable displacement compressor capable of varying discharge displacement in response to a displacement control signal through a coolant circuit to cool air passing in the duct, a means for controlling heat exchanger ability to adjust the extent of cooling of the heat exchanger, and a means for controlling a target blow-off air temperature to control the temperature of air blown out to the vehicle interior to a prescribed temperature. The target value of the adjusted temperature of the heat exchanger by the means for controlling heat exchanger ability is controlled to a temperature obtained by deducting a temperature equivalent to a temperature rise caused when the air is passing in the duct from the target blow-off air temperature by the means for controlling target blow-off air temperature in this vehicular air conditioner.
