Aeration device for the passenger compartment of a vehicle, and in particular a heating or air conditioning installation for a motor vehicle.

摘要

The invention relates to a ventilation device for the passenger compartment of a vehicle, in particular an installation for heating or air conditioning system for a motor vehicle. The aeration device comprises a fan 112) in order to renew the air of the passenger compartment (10) and a filter (18) to adsorb the odoriferous substances or noxious contained in the flow of air delivered by the fan (12). br / according to the invention, the filter (18) is designed so as to obtain, for a spectrum as wide as possible of the odoriferous substances or harmful, a filtering effect based on the adsorption of the odoriferous substances or noxious and their gradual desorption, greatly slowed down. A high concentration temporarily odoriferous substances or noxious is thus transformed into an extremely low, but for a long time, which, with a sufficiently high, remains below a threshold assigned odor or pollution.
