<p>PURPOSE:To conduct comfortable heating constantly by controlling the rotational number of a blower in accordance with the state of temperature of cooling water for an engine at the time of heating in an air conditioning device for a vehicle. CONSTITUTION:A device detecting the temperature T1 of the cooling water for the engine and the control device 20 comprising a control circuit controlling the maximum rotational number of the motor of the blower 2 in accordance with the temperature T1 in the case when an air conditioning device is in a heater mode and other components are provided in the air conditioning device 1 and the adjustment of air flow of the blower 2 is conducted not only in accordance with the difference between a set temperature T3 and a temperature T2 inside the room of the vehicle but also based on the value of the temperature T1 of the cooling water for the engine at the time of operation in the heater mode. Accordingly, the rotational number N of the blower 2 increases as the difference between the set temperature T3 and the temperature T2 inside the room of the vehicle becomes large, while the maximum value of the rotational number thereof varies according to the temperature T1 of the water. That is, the maximum rotational number is large when the temperature T1 is high, while it is small when the temperature T1 is low.</p> |
