Abstract
An air flow control for a ventilation, heating, or air conditioning unit of a motor vehicle, having a housing with a cold air passage with a first inlet opening and with a hot air passage with a second inlet opening. At least one heating heat exchanger is disposed in the hot air passage in order to heat the air in the hot air passage with a mixing chamber for mixing a first partial air flow from the cold air passage and/or a second partial air flow from the hot air passage. The mixing chamber is disposed downstream of the hot air passage and of the cold air passage. A mixing flap substantially closes the first inlet opening. The housing downstream of the mixing chamber has a first outlet opening and at least one second outlet opening for the flowing of air out of the mixing chamber.
