Abstract

The mathematical model of the indoor air pollutant diffusion is derived from the basic difference equations of diffusion and the continuous emission model of pollution point source by using the interior paint as the release source in a newly-renovated hermetic indoor environment. Based on the derived mathematical model, the indoor air pollutant concentration is calculated and the formaldehyde concentration is experimentally verified. The study shows that the formula computed result is consistent with the experimental result and the error is small. The model is feasible as the error in that level is permitted. The model can provide the quantitative basis and technical support for indoor air quality assessment and indoor pollutant control.
