Zusammenfassung:	PURPOSE:To obtain a proper cooling in a car by following the indoor temperature of the car at a fixed time interval on the basis of the detection of the temperature for driving an indoor fan in accordance with the state of the grasped relation between the thermal load of a car body and the cooling capacity. CONSTITUTION:A car indoor temperature signal by a temperature detector 18 is amplified and introduced into a CPU14 via an input/output circuit 15. There, it is accumulated as data in an RAM17 at a fixed time interval, and the transition of the car indoor temperature is computed on the basis of comparison. In case the car indoor temperature is over the set value of an ROM16 and risen at the detection of the fixed time interval, the necessity of the drive of an indoor fan 12 is decided. By this decision, a drive command of the indoor fan 12 is given to operate an auxiliary relay 19 via the input/output circuit 15 for driving the indoor fan 12.
