<p>A HVAC system for motor vehicles, capable of meeting customer specifications for air flow distribution and thermal balance and comprising a cold air supply zone (CZ), a hot air supply zone (HZ), a primary mixing chamber (PMC), main mixing chamber (MMC) for mixing hot and cold air, and an integrated Foot Flap (FF), duct (DT) and baffles (BF) for controlling the air entering into foot outlet (FO), when the HVAC is in Foot mode and also the air entering into main mixing chamber (MMC) when the HVAC is in any other mode than Foot mode. The foot flap integrated with a duct and baffles functions as a single unit and allows a portion of Hot air coming from hot zone (HZ) to enter directly into main mixing chamber (MMC) without getting in touch with cold air coming from cold zone (CZ). Baffles (BF) collect a portion of hot air from hot zone (HZ) and guide it into duct (DT).</p> |
