合肥地区居住建筑不透明活动外遮阳节能率分析与应用

Analysis and Application of Energy Saving Rate of Exterior Shading for Residential Buildings in Hefei

建筑外遮阳是降低建筑空调能耗的一个重要的措施。通过模拟分析不同的外遮阳形式在夏热冬冷地区居住建筑中应用前后所获得的遮阳节能率,通过分析得出,相对于固定式外遮阳、半透明活动外遮阳和活动百叶外遮阳,不透明活动外遮阳卷帘所获得的遮阳节能效果最好。另一方面,介绍活动卷帘(不透明)外遮阳设施设计技术指标和在建筑中应用技术要点,为该项技术在绿色建筑中应用提供参考。

Building exterior shading is an important measure to reduce energy consumption of building air conditioning system. Through the simulation analysis of different forms of sun shading shading obtained in hot summer and cold winter region residential building before and after the application of the rate, according to the analysis, compared to fixed external shading, shading and translucent activities activities of louvres, opaque movable external sunshade curtain volume shading energy-saving effect of the best. On the other hand, this paper introduces the design index of movable curtain （opaque） shading facilities and the technical points of application in building, which provides reference for the application of this technology in green building.
