摘要
针对某商场空气幕挡烟的实际应用,采用FDS对空气幕挡烟效果进行探讨,主要分析不同部位起火时的空气幕挡烟效果。结果表明,空气幕距离火源越远,挡烟效果越差;应用空气幕挡烟的前提是保证着火区排烟系统设置合理。
Taking the air screen in certain mall as an example,numerical simulation was adopted to discuss the feasibility of applying air screen in malls and mainly analyze the effects of air screen when fire broke out at different positions.The results manifest that the farther air screen is away from fire brand,the worse its smoke-proof effect exerts.In addition,the premise of applying smoke-proof air screen relies on that there should be sound purging system in the burning area.
