摘要
简述了双层玻璃幕墙的节能原理。应用CFD技术对夏季简化的双层玻璃幕墙模型进行热工分析,揭示了热通道内的气流运动规律,指出双层玻璃幕墙存在的问题,并比较了几种不同设计方案的差异。最后,计算出幕墙综合传热系数和热效率两个关键参数,可为双层玻璃幕墙的工程设计提供参考。
The principle of energy conservation of double skin facade is briefly described. Application of CFD technology to the natural ventilation in summer on a simplified double skin facade model for thermal analysis reveals the current features inside the thermal channel and the existing problems of double skin facade.Several design models are compared.Finally,the overall heat transfer coefficient and thermal efficiency are calculated.These two key parameters are used for evaluation and design of double skin facades.
