某商场分散式排烟系统设计的探讨

A discussion on the design of discrete-type smoke extraction system in an emporium

以某大型综合性商场为例,运用建筑防火性能化设计理论和方法,对商场的排烟系统进行了分析计算,在数值模拟计算的基础上提出改进意见,并针对商场的不同部分的建筑结构特点给出不同的防排烟措施。

The present paper intends to give a discussion on how to use the performance-based method to design a mechanical smoke extraction system of an emporium. First of all, problems involving the method of design are analyzed. Then, based on the calculation, some advanced ideas on how to improve the system's efficiency are presented. To this end, different smoke treatment versions corresponding to the building's structure have been proposed to achieve the best effect. It can be concluded that: by carefully designing the ventilation port and choosing the proper flow rate, the mechanical ventilation project will be able to extract the smoke smoothly. Therefore, mechanical ventilation has proved to be a more advantageous method to extract smoke than natural ventilation.
