Model prediction of indoor particle concentrations in a public school classroom

Indoor particle concentration and its relationship with outdoor particle level were investigated using a macroscopic indoor air quality model for a classroom ventilated naturally. The model was validated with measurement data obtained from an optical particle analyzer's measurements. Reasonably...
