METHOD AND SYSTEM OF MICROCLIMATE NORMALISATION Russian patent published in 2009 - IPC B60H3/06 F24F3/16 

FIELD: transport.

SUBSTANCE: method and system of microclimate normalisation in vehicle passenger compartment equipped with ventilation, heating and air-conditioning system consists in air purified from particles and supplied by fan into passenger compartment via two circuits. Via first open circuit inlet ambient air after treatment is supplied to passenger compartment, via second closed circuit air is intaken from passenger compartment, treated and supplied back into passenger compartment. Control of air supply into passenger compartment is effected by control block assembled with actuating mechanism. Air supplied into passenger compartment via second circuit is additionally purified from harmful substances by additional filtration-sorbing block. Pumping of air through layers in cleaning block is performed by pressure fan with pressure exceeding gas-dynamic resistance of passenger compartment and cleaning block together with all local resistance of air tracts and ventilation system components, heating and conditioning, and it creates increased pressure in passenger compartment amounting to no less than 5-10 Pa as compared with outer air pressure.

EFFECT: increase of efficiency of air purification in passenger compartments of vehicles, reduction of power consumption for driving system elements.
