高层综合楼排烟系统设计分析与计算校核

高层综合楼功能复杂，人员密集，火灾危险性大，而火灾中烟气的毒害和窒息作用是致人死亡的最主要原因。因此，对该类建筑进行必要的排烟设计，既可以保证人员疏散安全，也有利于进行消防扑救。以某高层综合楼的排烟设计为例，对其排烟系统设计进行分析，重点对其排烟风机的排烟量进行计算校核，并提出了在排烟系统设计时应注意的问题，为设计人员及消防设计审核人员提供参考。

Analysis and calculation of purging system in a high-rise building

High rise building has complex function, a dense crowd and high fire risk. And the main reason of death is smoke. Smoke can hold toxic gas and make people choked. So it is necessary to design the purging system of high rise. It can not only assure the safety of crowd, but also benefit the fire fighting. In this paper, the purging system of a high rise building was taken as the research object. The design of the purging system was analysed, especially audited the smoke venting quantity of the smoke ventilators by using quantitative calculation. Some questions, which should be considered when designing the system, were put forward in this paper. It provides a reference for the designers and auditors.
