Air quality in transportation Cabins - Part II: Air quality in a truck cabin

Tan, Zhongchao / Cheng, Xiaoying / Tay, Richard

A portable air quality monitoring system was developed to monitor the indoor air quality (IAQ) in a truck cabin that was used for in-city transportation. Temperature, relative humidity, and the levels of various airborne contaminants (CO, CO₂, NO₂, and particles) were measured in the truck cabin between August 16 and September 20, 2005. Temperature and relative humidity were found to be outside the comfort level recommended by ASHRAE. The concentrations of CO, CO₂, and NO ₂ were acceptable, although the levels of CO and NO₂ were occasionally greater than the recommended standards. The particle number was higher than those in a typical office. Further analyses showed that the temperature and relative humidity in the truck cabin changed with the time of the day, while other IAQ parameters did not show obvious variation. Comparison with the field data in motorcars and airplanes showed that the concentrations of CO and NO₂ were higher in the truck cabin than in other transportation cabins.
