摘要
为探求合适的排烟口与送风口的尺寸关系,通过理论分析,推导出影响正压送风排烟效果的通风因子,该通风因子同排烟口与送风口的面积比成正相关关系,进行了全尺寸试验。结果表明,排烟口与送风口面积比为2∶1时可以达到较好的排烟效果。研究结果可为正压送风排烟在火场中的实战应用提供一定的理论与技术指导。
In order to find proper proportion of smoke exhaust vent to air outlet, by theoretical analysis, derive ventilation fac- tor influencing effect of air supply and smoke exhaust, and the ventilation factor is positive correlated with proportion of smoke exhaust vent to air outlet, then full-scale experiment is carried out, and the results show that when the proportion of smoke ex- haust vent to air outlet is 2 ： 1 ,the smoke exhaust effect is the best. the results can give theoretical and technical guide for ap- plication of positive air supply system in fire.
