Abstract
A motor-vehicle heating and/or air-conditioning device has an air intake chamber (12) with an inlet (14) for outside air (AE), an inlet (16) for recirculated air (AR) and a flap (18) for selectively controlling the inlets. A motor-driven fan unit (28) downstream of the air intake chamber has a casing (30) accommodating a centrifugal turbine (34) driven by a motor (48). The fan unit takes in air flow axially then delivers it tangentially. The. combination formed by the outside-air inlet (14) and the recirculated-air inlet (16) extends on either side of an arbitrary plane (P) passing through the axis of rotation (50) of the motor (48), the latter being located on the same side as the air inlets (12) and (14), which makes it possible to reduce the axial space taken up.
