Abstract
An automobile air conditioning device includes a ventilation system with a ventilation fan for discharging air contained in a passenger chamber from the vehicle. A dew condensation detector is adapted to detect a predetermined relative humidity for a dew point at which dew condensation on a rear window glass of the vehicle is presumed to occur. A controller actuates the ventilation system when the dew condensation detector detects the dew point while the vehicle is running.
