Vorrichtung zur Heizung und/oder Klimatisierung eines Fahrzeuginnenraumes mit reduziertem Druckverlust

The heating and/or air conditioning system consists of a housing (18) located behind the dash panel between the engine (C) and passenger (H) compartments and containing a radiator (42) and outlets for de-frosting (52), ventilation (66) and warming the feet (58). The incoming cold air is fed into a cold air chamber (44) situated towards the rear of the housing on the ventilation outlet side, while the warm air chamber (46) is situated at the front of the housing, on the side of the de-frosting and foot warming outlets, being fed with air from the cold air chamber that has been heated as it passes through the radiator in a generally horizontal direction. In addition, the cold and warm air chambers are connected to at least one mixing chamber (74, 76) feeding the outlets.
