摘要
随着高层建筑如春笋般拔地而起,建筑火灾的逃生与救援问题得到了人们的高度重视。在众多火灾隔烟技术中,空气幕在建筑火灾防烟领域的效果与可行性已经得到了广泛证实,针对空气幕的研究众多甚至近乎饱和,然而关于复式空气幕却鲜有人研究。本文旨在为空气幕的防烟领域带来新思路,同时期望为空气幕的设计提供建设性参考。
With the rise of high-rise buildings like bamboo shoots, building fire escape and rescue issues have been highly valued. Among the many smoke insulation technologies, the effect and feasibility of air curtains in the field of building fire and smoke prevention have been widely confirmed. However, in the case of many detailed and even nearly saturated studies on air curtains, there are few studies on duplex air curtains. Numerical simulations using FDS confirmed the possibility of the use of the double air curtain in building smoke prevention, and found that its smoke prevention effect was no less than that of a single air curtain, and the greater the distance between the two monomers constituting the double air curtain, the effect the better. This paper aims to bring new ideas to the smoke prevention field of air curtains, and at the same time hopes to provide a constructive reference for the design of air curtains.
