METHOD OF ASSESSING FILTRATION EFFICIENCY OF PASSENGER COMPARTMENT AIR FILTER DURING HEATING, VENTILATION AND AIR CONDITIONING (HVAC) OF VEHICLE Russian patent published in 2019 - IPC B60H3/06

Abstract RU 2698626 C2

FIELD: physics.

SUBSTANCE: invention relates to heating, ventilation and air conditioning systems. To determine filtration efficiency of air filter of passenger cabin during heating, ventilation and air conditioning (HVAC) of vehicle determine concentration of pollutants in atmosphere outside vehicle, efficiency of passenger compartment air filter and HVAC air flow rate. Concentration of pollutants in the passenger cabin is calculated based on a certain concentration of pollutants in the atmosphere, the efficiency of the air filter of the passenger cabin and the air flow rate HVAC.

EFFECT: improvement of air cleaning indices in vehicle cabin.
