针对某会议中心主门厅排烟方案的设计,运用性能化方法,根据门厅类建筑实际情况,选取自然排烟方案,计算得出排烟口面积、补风口面积等自然排烟参数。通过软件模拟烟气蔓延情况,对主门厅排烟方案进行了验证。结论表明,按照NFPA 92B的方法计算得到的自然排烟口面积和模拟计算中设定的自然排烟口位置可以维持烟气在较高的高度,能够达到较好的烟气控制效果,满足消防设计要求。
Aiming at the design of a smoke exhaust scheme in the main hall of a conference center, the performance of the method is used to select the natural smoke exhaust scheme according to the actual situation of the hall building, and the natural smoke exhaust parameters such as the exhaust port area and the fill air outlet area are calculated. Through software simulation of the spread of flue gas, the main hall smoke exhaust scheme was verified. The conclusion shows that the natural exhaust port area calculated according to the method of NFPA 92B and the natural exhaust port position set in the simulation calculation can maintain the flue gas at a higher altitude and achieve better flue gas control effect, Design requirements.
