摘　　要：高大空间建筑因内部空间广阔、人员密度大、功能复杂、可燃物较多等因素,一旦发生火灾,烟气和火焰的传播速度较快,给灭火和人员疏散带来困难。排烟系统设计在高大空间消防设计中的作用尤为重要。文章以高大空间防排烟系统在工程设计中的一般流程为大纲,对高大空间排烟系统的高大空间防烟区分划分、排烟量计算、机械排烟设计、排烟设施及控制方法进行探讨。Due to the vast internal space,high personnel density,complex functions,and more combustibles,once a fire occurs,the smoke and flames spread quickly,which brings difficulties to fire extinguishing and personnel evacuation.The design of smoke exhaust systems plays a particularly important role in the design of fire protection in tall spaces.Based on the general process of smoke prevention and exhaust system in tall space in engineering design,this paper discusses the division of smoke prevention and exhaust in tall space,the calculation of smoke exhaust volume,the design of mechanical smoke exhaust,the smoke exhaust facilities and the control method of smoke exhaust system.
