广州某办公楼外窗对空调冷负荷的影响分析

Analysis of the External Windows' Impact on Cooling Load of an Office Building's Air-conditioning in Guangzhou

采用DeST软件对广州某普通办公楼8种类型外窗在不同遮阳措施条件下的空调冷负荷进行了模拟分析。分析表明:增加浅色窗帘遮阳,并更换原建筑外窗普通6mm单层玻璃为镀Low-e膜中空玻璃(低透型)或中空玻璃后,节能率可分别达到13.9%和10.4%,节能效果显著。这对广州地区普通办公楼外窗的设计有一定的指导作用。

In the cases of eight kinds of external windows with different shade measures, the cooling load of an office building＇s air-conditioning system was simulated and analysised by DeST. It showed that installing light color curtains and replacing the ordinary 6mm glass with low-e （low permeability）or hollow glass would make the energysaving rate up to 13.9% and 10.4%. It can be referenced for other projects.
