摘  要   采用 Airpak 軟件對(duì)世博衛(wèi)生間室內(nèi)污染物濃度及熱環(huán)境進(jìn)行模擬。通過改變通風(fēng)方式、換氣次數(shù)、排風(fēng)口高度等
方式,對(duì)比了不同模擬工況下污染物濃度。模擬得出采用上送風(fēng)下分散排風(fēng)方式的效果最好,為改善廁所污染物濃度和熱環(huán)
境提供了方法和理論依據(jù)。

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.
