ABSTRACT:
When a vehicle approaches a station, this is detected by means of spot detection and vehicle velocity detection, and operation of a ventilator is slowed down or stopped when the vehicle is at a stop at the station. This allows the numbers of revolutions of an indoor blower, an outdoor blower and a compressor of an air conditioner to be reduced by half, with the heat load being reduced by half. This operation control can reduce the powers of sound sources constituting the interior noise, thereby reducing the interior noise.
