The invention concerns a heating, ventilating and/or air conditioning device comprising at least an air distribution channel having a downstream end, and at least an air diffusing element arranged at said one downstream end. The invention is characterized in that the air diffusing element ( ) comprises a support ( ) provided with through orifices ( ) and covered over at least one of its faces with a material ( ), having air resistance ranged between 10 N.s.m and 180 N.s.m .

Heating, ventilating and/or air conditioning device comprising at least an air diffusing element in a motor vehicle passenger compartment

The invention concerns a method for reducing preheating time and for homogenizing temperatures in a passenger compartment, for example of a motor vehicle, wherein the preheating dynamics is improved, which consists in adjusting soft air diffusion air speed in an optimized range of values. In one embodiment, the air circulating device comprises at least a ventilator ( ) and at least a soft air diffusion conduit ( ), having at its open end an air permeable panel ( ) which ensures a soft air diffusion in the passenger compartment. The invention is characterized in that the ventilator, the conduit ( ) and the panel ( ) are dimensioned so that, at maximum ventilated air flow rate, the diffused air speed ranges between 2 and 5 m/s. The device further comprises at least a ventilation conduit ( ), said conduit being dimensioned so that, at maximum air flow blown by the ventilator, the air speed at the ventilating nozzles substantially ranges between 2 m/s and 10 m/s. The invention is applicable in particular to a motor vehicle passenger compartment.

Method for circulating an air flow in a passenger compartment by soft diffusion and device therefor

The invention relates to a device for delivering ventilation air to the front of the cabin ( ) of a motor vehicle, this ventilation air being delivered by a delivery box ( ) of a heating, ventilation and/or air-conditioning unit, said device comprising at least one ventilation pipe ( ) supplying at least one air vent ( ) provided in the dashboard ( ), said ventilation pipe ( ) being formed in a delivery module ( ) which runs transversely under the upper face ( ) of the dashboard ( ), and splitting downstream in the direction of flow of the ventilation air into at least one &ldquo;gentle&rdquo; ventilation pipe ( ) which opens onto the, upper face ( ) of the dashboard ( ) via ventilation orifices ( ) of large cross section and into at least one &ldquo;forced&rdquo; ventilation pipe ( ) which supplies at least one air vent ( ) of small cross section arranged on the dashboard ( ) facing the cabin ( ). At least one air distribution shutter ( ) is provided at the junction between the three pipes ( ).

Device for delivering air at the front of the cabin of a vehicle

The air conditioning installation has air treatment and distribution means in a housing with air outlets on an upper face. De-icing and central aeration ducts are in an oblong diffusion unit above the upper face of the housing and under the upper fascia of the dashboard. This upper fascia has a diffusing surface in excess of 1.5 dm and preferably in excess of 2.5 dm . In an embodiment, the diffusing surface is produced by multiple perforations.

Air conditioning installation for a vehicle, with gentle diffusion

A heating and/or air conditioning device for a motor-vehicle passenger compartment has an air-inlet chamber and a blower for installation in a rear part of the vehicle, a treatment and distribution device for installation in a front part of the passenger compartment), and a connecting duct for connecting the blower to the treatment and distribution device.
