关于地铁防排烟系统的一些优化设计

Some Optimum Design about Smoke Management Systems of Metro

针对《地铁设计防火标准》、《建筑防烟排烟系统技术标准》中关于专用风机房、内走道补风口提出的新要求,从结合出入口设置地面排烟风机房、防烟风机房、内走道补风口等方面进行分析总结,结合工程实践给出了优化设计思路和对策。

Aiming at the new requirements of special fan rooms and air supply outlets in Standard for fire protection design of metro and Technical standard for smoke management systems in buildings,based on the analysis of ground smoke exhaust machine room combined with entrance and exit、smoke prevention fan room and air supply outlet of inner aisle,the optimum design ideas and countermeasures are given in combination with engineering practice.
