中文摘要：

以北京市未安装空调的某户住宅为研究对象,模拟计算了测试房间的室温,并将模拟结果与实测数据进行了比较。结果表明,住宅室内热状况对天空背景辐射、外窗遮阳、邻室室温、房间通风换气量等扰量的变化十分敏感。在DeST软件的应用过程中,应真实反映上述各个因素的实际变化规律,才能使模拟计算结果与实际相符。

英文摘要：

With an unconditioned residential unit in Beijing as the test object,simulates the indoor temperature,and compares the simulated and measured temperatures.As a result,the indoor thermal environment is very sensitive to the factors of sky radiation,exterior window shade,indoor temperature of neighboring rooms and natural ventilation conditions.During the use of DeST software,the actual variation of the above factors should be described to match the simulated and test results well.
