Experimental Study to Analyze Various Parameters Improving the Cabin Air Quality 2022-28-0456

Cabin Air quality is the measure of quality of air within the vehicle. Cabin air quality is not just important for comfort but for safety as well [1]. For decades, scientists have studied the air quality outside of automobiles. The in-cabin microenvironment has become a significant source of exposure to numerous air pollutants, such as particulate matter (PM), volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), carbon monoxide, and nitrogen oxides, etc. [4]. There are various physical parameters such as filters, cabin temperature, air exchange rate, A/C ON or OFF condition and direction of flow of air inside the vehicle cabin, which can affect the cabin air quality and purification time. The air exchange and its rate being of highest importance [2]. The paper consists of various experimental results to check the effect of these parameters in improving the cabin air quality. The paper consists of data related to PM 2.5 which is one of the most significant contributors in hampering the cabin air quality. The paper clearly demonstrates the procedure followed to create high concentration of PM 2.5 inside the vehicle cabin, and how that PM 2.5 concentration value inside the vehicle cabin be reduced by varying air exchange rate, changing the kind of filter in HVAC unit, changing direction of air flow inside the vehicle cabin, or changing the mode of air intake.
