摘　　要：研制了链牵引式外遮阳百叶窗,设计了百叶翻转机构及升降机构,可以调整叶片角度,实现叶片上卷或下放.计算百叶窗的综合遮阳系数,确定了其遮阳性能等级为5级.以上海地区为例,利用DeST-h分析了百叶窗对建筑能耗的影响,结果表明,采用百叶窗较无遮阳及水平遮阳板两种方式,冷负荷分别减少180.55,kW·h和62.95,kW·h.利用SolidWorks对叶片结构进行了静态仿真模拟,结果表明,叶片的抗风压强度在合理范围内.Extemal shading blind with chain traction was developed. Louver flipping mechanism and lifting mechanism were designed. It can adjust the shutter angles to make the louvers roll up or down. The comprehensive shading coefficient was calculated to determine its shading performance, which is at the fifth level. In Shanghai, the blind＇s effect on building energy consumption was analyzed with DeST-h. The results show that, compared with no shade and horizontal sun visor, the cooling load decreased by 180.55 kW＇h and 62.95 kW.h respectively. The louver＇s structure was statically simulated with SolidWorks. The result shows that the wind pressure-resistance strength of the louver is in a reasonable range.
