摘　　要：通过WUFI系列软件对上海某典型房间进行建模,比较了室内动态热环境和稳态热环境下的空调负荷;并利用模拟计算的室内温湿度数据,对外围护结构热湿传递进行了模拟。模拟结果表明:动态热环境下通过墙体的湿流量比稳态工况小,空调负荷更低。A typical room in Shanghai was modelled using WUFI series software.The difference between air conditioning loads in dynamic and steady thermal environment was analyzed.Using the simulated indoor temperature and humidity data,the heat and moisture transfer of the external envelope was simulated.The simulation results show that the wet flow through the wall in the dynamic thermal environment was smaller than the steady environment,and the air-conditioning load was lower.

关 键 词：动态热环境 空调负荷 热湿耦合
