夏热冬冷地区内呼吸幕墙的节能效果分析

Analysis of the Energy Saving Effect of the Double Skin Facade in Hot-summer and Cold-winter Zone

本文通过比较夏热冬冷地区单层幕墙建筑和内呼吸幕墙建筑的能耗,对内呼吸幕墙的节能效果进行分析。在夏季时,与单层幕墙相比,使用内呼吸幕墙可以减小不同朝向的外区的夏季空调冷负荷。其中,西向和东向的呼吸幕墙的节能效果最好,北向呼吸幕墙的节能效果一般。在冬季时,与单层幕墙相比,呼吸幕墙可以减小不同外区的空调热负荷。内呼吸幕墙建筑的全年空调能耗约为单层幕墙建筑的80%～85%。两种内呼吸幕墙相比,中空玻璃在内层的内呼吸玻璃幕墙更节能。

This paper analyzed the energy saving effect of the double skin facade in the hot-summer and cold-winter zone through the comparisons of the thermal loads of the buildings respectively with the single layer glass facade and the two double skin facades.In summer,compared with the single glass layer facade,the double skin facade can effectively reduce the cooling loads of the different outer zones with different orientation.The east and west double skin facades have the best energy saving effects,the north double skin facade has little effect.In winter,compared with the single glass layer facade,the double skin facade can reduce the heating load.The energy consumptions of the buildings with the double skin facades are the 80%-85% of the energy consumption of the building with the single glass layer facades.Compared the two double skin facades,the double skin facades with insulating glass at the inner layer have better energy saving effect.
