摘要
The upgrading of contamination control and air quality in the lavatory environment with poor exhaust ventilation systems is studied. Using this new ventilation design, the distributions of airflow and polluted odors (contaminant aerosol particles) in normal lavatories are explored in order to improve comfort conditions. Considering the turbulent and unstable behavior of the airflow, residence time theory is applied to describe the characteristics of aerosol particles in terms of probability distribution functions. A complete numerical simulation of airflow and contaminant particles (odors from excreta) is undertaken and the results of a typical men's room and a typical women's room are presented.
