Heating or air conditioning plant for road vehicle interior

摘要

An air feed channel with outlet apertures is provided for air outlet in a middle plane of the vehicle interior, which via a cold air inlet is connected with a cold air channel and via a hot air inlet is connected with a cold air flap which is part of the cold air inlet. The geometry of the cold air flap (25) and the arrangement of its pivot axis (26) in the air feed channel (19) are so arranged, that the cold air flap in its opening position extends, preferably centrally, with its one longitudinal edge (521) into the cold air inlet (21).
