PURPOSE:To obtain a comfortable air conditioning including insolation correction by a metod wherein an air conditioning factor is controlled according to insolation to which a car is subjected and an electrical treatment is applied to delay response to control of the air conditioning factor. CONSTITUTION:An amplification unit 3 drives a transducer 4 according to a compound valtage signal generated by variable resistor 1, internal temperature sensor 2a, external temperature sensor 2b, potentiometer 3a and correction cirduit 6, controls an opening of damper through a driving unit 5 and thus adjusts car room temperature as desired. A photodiode 6a in the correction circuit 6 inputs voltage according to the insolation to a transistor 6g. In this case the change is kept slow by a presence of time constant circuit including condenser 6b. A control of the air conditioning factor is therefore not carried out when the car comes in and out of the shade temporarily. |
