摘　　要：建立一个简化的中庭建筑模型,利用Airpak软件模拟单独风压作用和耦合热压风压作用两种状况下的室内自然通风效果,然后分别改变窗口位置和增加室内热源强度,根据模拟计算结果,统计建筑内各房间空气换气次数,分析这几种因素对室内自然通风的影响,研究表明热压和风压共同作用时,对迎风面房间起促进作用,对背风面房间产生抑制作用,通风开口位置和室内热源强度是影响室内气流流动的关键因素。A simplified atrium building model was set up, by using Airpak software to simulate indoor natural ventilation effect with wind pressure separately and coupling wind pressure and hot pressing, and changing the window position and increasing indoor heat source intensity to statistic air ventilation rate of each room in the building with the simulation calculation results. The effect of these factors on the indoor natural ventilation was analyzed. Studies have shown that it produce promoting effect to the windward side room and inhibitory effect on leeward side room under the effect of thermal and wind pressure. The ventilation opening position and indoor heat source intensity is the key of influencing the indoor air flow.
