摘要
地下车库因其本身特殊结构,决定了在发生火灾时内部烟气难以排除,给火灾扑救和人员疏散带来不便.通过利用FDS对地下车库火灾烟气扩散和正压送风机工作效果进行数值模拟,研究正压送风机在地下车库灭火应用的最佳时机,为消防员对地下车库火灾进行烟气控制提供了技术参考.
Abstract
The difficulty to exhaust the fire smoke in the internal space of the underground garage determined by its special structure brings inconvenience to the firefighting and evacuation. Using FDS the author simulated the smoke spread in underground garage fire and the operating effect of positive pressure ventilator to study the best application time of the fan in similar structure and provide technical reference for the fire fighters to carry out the smoke control on such fire ground.
