PURPOSE:To reduce noise accompanying the variation of wind volume and also provide a pleasant wind-speed feeling by setting wind volume according to the noise level in a car room and controlling a wind volume variable means. CONSTITUTION:A car speed is detected as a noise level in a car room by means of a car speed sensor 47, and this, together with the detection signals of other sensors 42-45, is inputted into a controller 41. The controller 41 conducts air conditioning by changing timewise wind volume according to a predetermined program. At this time, the noise level within the car room is inspected on the basis of the car speed to be detected. And wind volume in accordance with this noise level is set, and the impressed voltage of a blower fan 28 which acts as a wind volume variable means is controlled on the basis of a set value. As a result, the noise within the car is reduced, and also, a pleasant wind-speed feeling can be obtained. |
