Abstract:
An experimental study of the thermal characteristics of an existing office building with double skin façade(DSF)were conducted in hot summer daytime in Nanjing, China. The temperature distributions of the DSF and indoor environment were measured at different control modes of DSF. The results show that the energy consumption of the air conditioning system in room B with opened exterior vents, a closed interior façade, and an air cavity with shading was 21.0% less than that in room A with closed exterior vents, a closed interior façade, and air cavity without shading in 9.5 h. The temperature distributions of the DSF and indoor environment in both horizontal and vertical directions were decisively influenced by shading conditions. The usage of shading devices strengthens the stack effect on the air cavity. Compared to room A, the temperature distribution in room B is more uniform with smaller fluctuations. Meanwhile, the problem of overheating in the air cavity of the DSF is still present in all tested conditions.
通过对南京地区某双层玻璃幕墙建筑在夏季白天不同运行模式下的表皮各层和室内温度分布对比实测, 分析该建筑的热特性.结果表明:在9.5 h内, 房间B在外层通风口打开、内层表皮紧闭、中间遮阳完全启用的情形下, 空调系统能耗比房间A在内外层表皮均完全紧闭、无遮阳设施情形下减少21.0%.玻璃幕墙各层表皮和室内各状态点的温度沿水平和垂直方向的分布规律均受到遮阳状态的显著影响.中间遮阳设施的启用有助于强化热通道的烟囱效应.相较于房间A, 房间B的温度分布更加均匀.但在所有的测试工况下, 双层玻璃幕墙热通道的过热问题始终存在.
