Abstract
So that, in the case of a preferably air-cooled vehicle, the air-conditioning system responds rapidly to changing heated-air temperatures as well as fluctuations in volume, heated air and/or fresh air and/or circulating air or cooled air is together guided to a fan, is swirled together and mixed in this fan and is subsequently, by way of outflow ducts, guided to the vehicle interior. A blow-out temperature sensor arranged behind the fan continuously scans the temperature deviation of the mixed air from the adjusted desired temperature and, as necessary, automatically corrects the position of a temperature mixing flap provided in front of the fan.
