双层热通道玻璃幕墙研究进展及展望

STUDY ON DOUBLE SKIN FACADES: PROGRESS AND PROSPECTS

双层热通道玻璃幕墙一方面能稳定室内的温度、光照,增强通风换气功能;另一方面能提高幕墙的保温、隔热、降噪能力,节省能量损耗,因此双层热通道玻璃幕墙逐步发展为幕墙环保、节能的新方向。按照通风方式的不同双层热通道玻璃幕墙分为内循环和外循环双层幕墙;国内外有关双层热通道玻璃幕墙的研究主要集中在热工性能、通风性能和影响因素等方面的研究;采用的主要研究方法为实验研究、理论研究和有限元数值模拟。介绍了双层幕墙的分类和工作机理,着重分析了国内外有关双层热通道玻璃幕墙热工、通风、影响因素和研究方法的研究文献,对近年来双层幕墙的研究进展进行了总结,简要介绍了双层幕墙的应用现状,阐述了国内外对双层幕墙研究思路的异同,最后探讨并展望了双层幕墙在建筑节能领域的应用前景。

The double skin facades( DSF) not only can stabilize the indoor temperature,illumination and enhance ventilation function; but also can raise the properties of thermal insulation,noise reduction ability and reducing the energy consumption of the curtain wall. So double thermal channel glass curtain wall will become the new direction of the environmental protection and energy-saving. According to the different ventilation pattern,the DSF is divided into an inner loop and outer circulation double skin facades. The researches at home and abroad mainly concentrate on the thermal performance,the ventilation performance and influence factors of DSF. The research methods are the experimental study,theoretical research and finite element numerical simulation. This paper introduces the classification and working mechanism of the DSF,focuses on the analysis of the domestic and international research literatures about the thermal performance,ventilation,influence factors and research methods of the DSF. It also summarizes the research progress of DSF in recent years,briefly introduces the application status,expounds the similarities and differences of research approach at home and abroad,and finally discusses the prospects of the DSF in the field of building energy-saving.
