摘  要   采用 Airpak 软件对世博卫生间室内污染物浓度及热环境进行模拟。通过改变通风方式、换气次数、排风口高度等
方式，对比了不同模拟工况下污染物浓度。模拟得出采用上送风下分散排风方式的效果最好，为改善厕所污染物浓度和热环
境提供了方法和理论依据。

Abstract   The software Airpak is used to simulate indoor pollution concentration and thermal comfort. By using
different ventilation types, changing the amount of ventilation or changing the height of the outlets, the pollution quality
concentrations are compared in different cases. The simulation results show that local exhaust is the best method for
ventilation, and it's helpful for the improvement of lavatory thermal comfort and decrease of pollution quality
concentration.
