Amount of Occupants' Exposure to Indoor Pollutant and Its Characteristics

WANG Jun*,ZHANG Xu(UVAC & Gas Institute,Tongji University,Shanghai 200092,China)  
A model to calculate amount of occupants' exposure to pollutants in room based on human inhale rate and breath model was presented and the characteristics of were analyzed in the case of different ventilation modes,outdoor fresh airflow volume and various pollutant intensities in terms of carbon dioxide and VOCs.Findings of the study indicated that exposure amount in the condition of displacement ventilation is less than that of mixing ventilation;and the amount decreased with the increase of outdoor airflow within a certain range and an optimum airflow existed.Generally,increasing the indoor pollutant emission would add to the exposure amount,and the increment was dependent on the type of ventilation.
