Abstract

One large chamber, and four box chambers were prepared to investigate the effect of the surface air velocity on Surface Emission Rate (SER) of perceived air pollutants, where four materials were tested. SER was calculated from the mean perceived air quality in decipol voted by trained panel. It was found that the greater the ratio of air change rate to loading factor, the smaller the SER of perceived air pollutants, and that the higher the surface air velocity, the greater the mass transfer coefficient and the greater the SER of perceived air pollutants.
