摘　　要：为解决现有节能玻璃窗节能灵活性不足和时节适应性差等问题,提出将保温卷帘与普通玻璃窗进行组合以实现节能的构想.分别以寒冷地区山西省太原市某简化建筑和实际建筑为考察对象,进行单因素分析和正交分析.首先,通过模型实验与DeST软件模拟进行对比,验证DeST软件模拟的可行性.其次,利用DeST软件模拟分析保温卷帘与普通玻璃的不同组合安装对考察对象全年冷、热负荷的影响.结果表明:南向玻璃窗配置外保温卷帘,在窗墙比为0.6和遮阳板框至少为1 m的情况下,可以有效降低冷、热负荷;北向玻璃窗配置内保温卷帘,在窗墙比为0.4的情况下,可以有效降低冬季热负荷;将保温卷帘与普通玻璃窗进行组合用于寒冷地区,白天收起卷帘进行采光和太阳得热,夜间放下卷帘减少辐射和对流失热,是一种较为灵活和理想的保温模式.In order to solve the widespread problems of existing energy-saving glass window such as lack of flexibility and poor adaptability of season and time,the idea of combining the thermal insulation shutter and ordinary glass window to realize energy saving was put forward.Taking a simplified building and a real building in a cold region of Taiyuan City Shanxi Province as the object of investigation,the single factor analysis and orthogonal analysis were carried out.Firstly,the feasibility of the DeST software simulation was verified by comparing the field experiment with the DeST software simulation,and then the influence of the thermal insulation shutter and ordinary glass window on the annual cold and heat load of the investigated object was analyzed by using the DeST software simulation under different combination installation conditions.The results showed that,the south window equipped with external insulation roll curtain,with the window-wall ratio of about 0.6 and a window-wall ratio of width of at least 1 m,which can effectively reduce the cold and heat load.For north window,two structures can be installed in the interior,with the window-wall ratio of about 0.4,which can effectively reduce the winter heat load.It is a more flexible and ideal thermal insulation modeto combinethe thermal insulation shutter with ordinary glass window in cold areas,rolling up the shutter during the day for daylighting and heat gain from the sun,and pulling down the shutter at night to reduce radiation and heat loss.
