南昌地区建筑夏季遮阳效果模拟研究

Simulation Research on Effect of Building Sunshade in Nanchuang

本文通过建立建筑模型,采用De ST-h软件,分别对不同朝向窗户的房间,分无遮阳、水平遮阳、深色窗帘、浅色窗帘的四种情况的室内气温和空调制冷能耗进行模拟计算。研究结果表明,建筑遮阳能够有效地防止太阳辐射,降低能耗,而且深色窗帘的遮阳效果最好,水平遮阳板次之,浅色窗帘效果最差。

Through making a building model and using De ST-h software, to simulate and compute interior air temperature and cooling consumption of a room of different toward the window. which has no building sunshade, has horizontal external sunshade, has dark curtain and light curtain. The research results show that building sunshade can prevent solar radiation from entering the interior efficiently and reduce the energy consumption of air conditioning system. Moreover, the dark curtain＇s effect is best, the horizontal external sunshade＇s effect is better and the light curtain＇s effect is good.
