外循环式双层幕墙节能性研究

Simulation Study on Energy Analysis of External circulating Double Skin Facade

应用CFD软件对上海市某外循环式双层幕墙热通道进行分析研究,考察热通道内空气的流场及温度分布。采用控制变量法,通过改变双层幕墙开口的位置以及幕墙间距这两个参数,分别计算分析开口位置和幕墙间距对幕墙整体节能性的影响,研究成果可用于指导实际工程中双层幕墙的设计计算。

The heat channel of double skin facade in Shanghai was simulated, the flow field and the distribution of temperature in the channel were investigated by using the CFD software in this paper. Applying the control variable method to this simulation by changing the position of the openings and the thickness of the double skin facade, their influence on the energy saving of whole double skin facade was calculated and analyzed respectively. The research can be used to guide the design and calculation of double skin facade in practical engineering.
