现有建筑幕墙热工性能试验检测及节能改造

Thermal Performance Testing and Energy-saving Renovation of Existing Building Curtain Walls

文中以某综合性大厦现有幕墙节能改造为例,先对现有建筑幕墙热工性能进行试验检测,再对改造后材料的传热系数、太阳得热因子进行计算。试验结果表明,其热工性能满足要求,符合节能降耗的改造目标,以期为类似节能改造项目提供参考。

Taking the energy-saving renovation of an existing curtain wall in a comprehensive building as an example,this article first conducts experimental testing on the thermal performance of the existing building curtain wall,and then calculates the heat transfer coefficient and solar heat gain factor of the renovated materials.The experimental results show that the thermal performance meets the requirements and meets the energy-saving and consumption reduction renovation goals,in order to provide reference for similar energy-saving renovation projects.
