防烟风机图1某紧急救援站防烟系统气流和人员疏散方向示意图模型的建立

截取横通道作为独立的研究对象，考虑到铁路疏散通道常见的安装方式，在横通道顶部安装射流风机，一方面angle.It was found that longitudinal smoke temperature exponentially and the decay coefficient increases with increas?spray angle.A modified coefficient K down was introduced exponential model to show the relationship between the and the longitudinal temperature attenuation and the longitu?smoke temperature distribution equation was established.help fire protection engineers to estimate thermal action structural design.
