Abstract: A heating, ventilation and/or air conditioning system (10) for an automobile vehicle, including a heating, ventilation and/or air conditioning housing (100) capable of allowing the thermal treatment of an air conditioning airflow to be used to maintain a desired temperature within the cabin, the heating, ventilation and/or air conditioning housing (100) having a primary distributor (132b, 133b, 134b) for the air conditioning air within the vehicle cabin so as to define a limited number of distribution configurations. The heating, ventilation and/or air conditioning system (10) includes an additional module (200) having additional distributors (212b, 213b) for the air conditioning airflow out of the cabin.

Abstract: The aim of the present invention to provide a heating, ventilation and/or air conditioning system (10) for an automobile vehicle, including a heating, ventilation and/or air conditioning housing (100) capable of allowing the thermal treatment of an air conditioning airflow to be used to maintain a desired temperature within the cabin, the heating, ventilation and/or air conditioning housing (100) comprising primary distribution means (132b, 133b, 134b) for the air conditioning air within the vehicle cabin so as to define a limited number of distribution configurations. The heating, ventilation and/or air conditioning system (10) includes an additional module (200) comprising additional distribution means (212b, 213b) for the air conditioning airflow out of the cabin.

Abstract: The present invention relates to a heating, ventilation and/or air conditioning unit, particularly for a motor vehicle interior, comprising a box (1) comprising at least one canal (10, 28, 96) having at least one wall (50, 64, 90) channelling an air flow in the box (1). The wall (50, 64, 90) comprises openings (52, 66, 92), and at least one sound absorption part (54, 60, 70, 72, 74) is arranged outside the canal (10, 28, 96) in contact with the openings (52, 66, 92).
