Zusammenfassung:	PURPOSE:To enable reduction of a fuel consumption by providing the second controller which controls a working hour of a compressor through fixing of a damper at the maximum point of a cool wind quantity, in a device having the first temperature controller through an air mix damper. CONSTITUTION:A room temperature signal of a sensor 9, a setting signal of a rheostat 11 and a damper opening signal through a potentiometer 12 are applied, a variation of an opening of an air mix door 6 is operated and an actuator 14 is operated through a transducer 13 by a control circuit 10. An air compressor 19 is turned on or off by a control circuit 17 at a temperature of a cool wind at an outlet of a vaporizer 3 through an electromagnetic clutch 19a. Then, when an atmospheric temperature exceeds 25 deg.C atmospheric temperature switches 20 and 20' are connected with each other, which are shifted to an a side, an electromagnetic valve 15 is strengthened and the door 6 is fixed at the maximum point of a cool wind quantity, at the same time an electromagnetic valve 21 is destrengthened and a warm water valve 22 is closed, then a setting voltage of a rheostat 18 is applied to the control circuit 17. Therefore, a working hour is reduced as control of the compressor 19 is carried out by means of on or off control in summer.
