Abstract
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.
