Effect of Ventilation and Filtration on Submicrometer Particles in an Indoor Environment
Abstract The effect of filtration and ventilation on reduction of submicrometer particle concentration indoors was investigated in an office building. The air‐handling system consisting of dry media filters and an air‐conditioning unit, reduced particle concentration levels by 34%. The characteristics of indoor airborne particles were dominated by, and followed the pattern of, outdoor air, with vehicle combustion aerosols as the main pollutant. The ratio indoor/outdoor particle concentration varied between 14 and 26% for different subzones. The presence of significant source of particles indoors was not observed. A simple mathematical model predicting evolution of particles indoors is presented. The model, based on a particle number balance equation, was validated with experimental data and showed very good agreement between predicted and measured parameters.
