摘要
采用DeST软件对长沙地区居住建筑5种类型外窗在不同朝向、热工性能、有无内遮阳条件下,窗墙比对单位面积供冷、热量的影响进行了模拟分析。探讨了外窗的朝向对单位面积年空调电费的影响。
Five kinds of external windows for residential buildings in Changsha region are investi-gated, and the simulative analysis on the influence of the window-wall ratio on cooling and heating per unit area under different orientations, different thermodynamic performance, with and without sunshade is carried out by DeST software. The influence of the orientations of the external windows on annual air-con-ditioning electricity cost per unit area is discussed.
