摘要
建筑门窗作为房屋建筑中透明和可以开启的围护结构,也是夏季隔热和冬季保温最薄弱的部分,从普通单层玻璃窗损失的能量高达建筑物能耗的50%,因此做好门窗,尤其是占门窗面积80%以上的玻璃的保温隔热是建筑节能的关键。以单层白玻、单层有色玻璃、单层SUN-E玻璃、Low-E夹胶玻璃、Low-E中空玻璃、贴有功能膜的普通透明玻璃为例,通过实验室检测方法,分析玻璃膜层位置对玻璃遮阳系数、可见光透射比的影响,并利用PKPM建筑节能分析软件,通过对实际建筑能耗的模拟,分析膜层位置,亦即玻璃正反面安装方位对建筑空调能耗的影响。
The building window, as the exterior-protected construction, which is transparent and can be opened, as well as the weakest fraxtion in the summer heat insulation and in the winter thermal retardation. The lose energy through the single-glass can occupy one half of the building energy. So, how to improve the thermal retardation and transparent of the window is the key of building energy efficieney, especially the glass, which occupies eighty percentage of the window area. Taking the single -glass, single-colored glass, single -SUN-E glass, Low-E doubling glass, Low-E hollow glass and the common clear glass which was pasted the function film as examples, through laboratory test, the effect of the glass membranous layer pasition on the shading coefficient and visible light transmission was analyzed. The PKPM analysis software of building energy efficiency was utilized, through the simulation of the practical building energy consumption, the membranous layer position was analyzed, namely the effect of the glass frontback installation site on the building air-conditioning energy consumption.
