ABSTRACT:
Disclosed is an air conditioner for use in an automotive vehicle. The air conditioner includes a timer circuit for deciding whether or not a given period of time has elapsed after an engine of the automotive vehicle has been started, an air quantity controller for limiting the amount of air to be introduced into a passenger compartment for a given period of time after an air cooling operation has been started, a compressor controller for prohibiting the operation of a compressor of the air conditioner for the given period of time to be decided by the timer circuit, a temperature sensor for detecting the temperature of the passenger compartment, and a switch portion for starting the compressor. The timer circuit, the air quantity controller, the compressor controller, and the switch portion are all provided in an air conditioner control unit. The control unit increases the amount of air within the first period of time when the temperature detected by the temperature sensor is greater than a predetermined value and when the switch portion outputs no instruction within the given period of time decided by the timer circuit. Alternatively, the control unit increases the amount of air from within the second period of time longer than the first period of time when the temperature detected by the temperature sensor is greater than the predetermined value and when the switch portion outputs an instruction for starting the compressor within the given period of time decided by the timer circuit.
