外墙保温对不同地区大型公共建筑冷热负荷的影响分析

随着我国建筑总量的增加,建筑能耗急剧上升,已成为我国的能耗黑洞,随之建筑节能逐渐被广大公民重视.目前建筑节能有很多措施,外墙保温就是其中一项.采用建筑热环境模拟工具DeST对同一大型公共建筑的冷热负行模拟计算,分析了在不同建筑气候分区下外墙的保温层厚度对空调负荷的影响,分析其有无节能效果,可为不同气候分区的大型公共建筑外墙隔热保温提供参考依据.

Impact of External Wall Thermal Insulation to Cooling and Heating Load for Different Regional Large-scale Public Buildings

With the increase of China’s construction total amount,there is a sharp rise in the building energy consumption.It has become the black hole of China’s energy consumption,and then our citizens pay attention to the building energy conservation gradually.Energy conservation of the building has a lot of measures,external wall thermal insulation is one of them.By using the building thermal environment simulation Toolkit DeST to calculate the cooling/heating loads for the same large-scale public building,it analyzed the effects of external wall thermal insulation layer thickness on air conditioning loads in different climate regions.And it analyzed whether it has energy saving effect or not.It can provide reference for external wall thermal insulation of large-scale public buildings in different climate regions.
