摘　　要：在建筑物内需要考虑防烟措施的楼梯间及前室,当楼梯间及合用前室(除首层外)均不具备自然通风条件时,应分别设置机械加压送风系统。首层扩大前室由于它的特殊性,是否必须采用机械加压送风系统,还是优先考虑设置自然通风系统,是一个值得讨论的问题。In the building,the stairwell and front room need to consider smoke prevention measures.When the stairwell and the shared front room(except the first floor)do not have natural ventilation conditions,a mechanical pressurized air supply system should be separately installed.Due to its particularity,the first floor expansion front room must adopt a mechanical pressurized air supply system or give priority to the natural ventilation system.This is a question worthy of discussion.

关 键 词：防烟楼梯间 首层扩大前室 自然通风 加压送风
