Motor vehicle ventilation, heating or air conditioning system is designed to receive a cartridge of a volatile treatment agent e.g. to combat micro-organisms

摘要

The ventilation, heating or air conditioning system has a compartment wall (2) with an aperture (7) for the insertion of a cartridge (1) containing a volatile agent that treats air by diffusion. The aperture is positioned so that the inserted cartridge lies across the air flow inside a container (11) with a porous wall (10). The container can be made separately from the compartment wall or integral with it, and the cartridge can be in the form of an absorbent substrate (4) inside a holder (3).
