摘要:
高层建筑防烟设计的目的是为了防止烟害并对烟气扩散进行控制,高效防烟装置应具有绝对隔烟、自由出入隔烟场所、不影响视野等功能。该文通过对烟气流动的机理分析,讨论了前室门的流场特性,用理论的方法建立了前室门处的流场。根据流线流量原理,提出在火灾时用防烟空气幕控制烟气的扩散。在前人试验研究的基础上,导出防烟空气幕的计算方法。
Abstract:
The purpose of smokeproof design for high-rise building is to prevent harm f rom smoke and to cont rol smoke-dif fusing. The effect ive smoke-prevent ing installat ion should have the funct ions such as absolute smoke insulat ion, going into and coming off the smoke-prevent ing place f reely, no conf inement of sight. T hrough analyzing smoke-flow f ield theoret ically, it is discussed that the effect of air flow on a hig h-rise building is a result of gas ex pansion by the temperature, the chimney effect , the outdoor w ind pow er and the vent ilation and air-conditioning system when firing. The f low field at the staircase door is theoret ically found. The w ay in w hich the diffusion of smoke is cont rolled is adv anced according to the principle of f low line-flow rate and based on the previous experimental researches by others, the calculat ion method for the smoke-prevent ing air curtain is infered in this paper.
