夏热冬冷地区可翻转双玻飘窗的能耗与经济性分析

The analysis on energy consumption and economy of reversible double-glass bay window in region of hot summer and cold winter

以南京地区典型年逐时气象参数为基础,以南墙外窗为对象,基于房间反应系数法,利用MATLAB编程分析其动态负荷变化,研究不同窗型的外窗,在使用不同窗框和玻璃材料条件下的全年能耗。结果表明,对于使用同种窗框和玻璃材料的平开窗和飘窗而言,飘窗的能耗大于平开窗的能耗,节能性好的窗框和玻璃材料,可以大大降低飘窗的能耗,可翻转双玻窗以进一步降低飘窗的能耗,且具有较好的经济性,适合在新建建筑中使用。

According to the hourly typical meteorological data in Nanjing,based on the response coefficient method of rooms,MATLAB is used to analyze the dynamical heating and cooling load of south window,as well as to study the yearly energy consumption of the window,which is made of different formses and glass materials.The result shows that the yearly energy consumption of south bay window will be more than that of casement window which is made of the same forms and glass material,but the energy consumption could be reduced if the bay window is made of energy-saving forms and glass material.And the reversible double-glass window could reduce the yearly energy consumption of south bay window more and has a good economy performance,so it is very proper to be used in new building.
