Investigation of Indoor Air Quality Characteristics in Automotive Compartments

Abstract

Abreast: Indoor air quality is an indicator level of human comfort confined with thermal conditions. This study mainly focuses on to predict the indoor air quality in inside car cabin at the time of traffic. Three different car has been used were SUV, sedan and hatchback types, mainly chosen is to differentiate the vehicle inside space diversely. To measure PM 2.5, PM 10, CO2, temperature and RH were recorded by using IAQ monitor with Data Acquisition (DAQ). At the time of measurement, four different cases are concern is window open (WO), window half open (WHO), window close (WC) and air conditioning with window close (ACWC). SUV achieved a better low temperature of 30ºC in ACWC and hatchback has a more temperature of 42.8ºC in WC due to vehicle space difference and severe concentrations of CO2 and particulate matter. RH are increased by the way of temperature get increased in indoor cabin. Hatchback indoor cabin rapidly generate CO2 emission, because indoor spaces is congested compared to other two cars. Windows and indoor spaces more in SUV, so outdoor pollutant easily get exposure to indoor pollutant while in the cases of window open (WO) and window half open (WHO).
