Temperature influence on air quality inside cabin of conditioned car

Abstract

In present work results of researches on influence of temperature on air quality inside vehicle are presented. One new car was tested in different atmospheric conditions, after conditioning in climate chamber. Air quality was evaluated on the basis of detected volatile organic compounds (VOC) and calculated as toluene equivalent. Samples were collected onto solid sorbents and examined, after thermal desorption, with the use of gas chromatography (GC) method with flame ionisation (FID) and mass spectrometry (MSD) detectors.

Evaluation of Typical Volatile Organic Compounds Levels in New Vehicles under Static and Driving Conditions

“…The vehicle interior pollution results from the emission of interior furnishing materials and the infiltration of engine exhausts and other exterior environmental pollutants [ 15 , 16 , 17 ]. In a vehicle cabin, the concentration of VOCs may be higher in comparison to concentrations found in public or private buildings [ 18 , 19 , 20 ], which may vary in time and are dependent on the interior temperature, humidity, ventilation, vehicle age and other parameters [ 21 , 22 , 23 ]. Wensing [ 24 ] proved that the concentrations of in-vehicle total volatile organic compounds (TVOC) decrease exponentially over a 40-day period from 35~120 mg/m 3 to 10~30 mg/m 3 .…”
