| 摘 要： | 细水雾灭火系统作为卤代烷系列灭火剂的替代产品之一，以其高效无毒、经济实用的优点，近年来在国际上研究得非常活跃。本文在受限空间内利用先进的材料热释放速率测量仪研究了细水雾与火的相互作用过程，并得到了以下结论：细水雾通过汽化吸热冷却燃料及氧化剂、体积膨胀隔氧以及吸收热辐射降低对燃料的热回馈等效应与火相互作用，达到控制和扑灭火灾的目的，在受限空间内汽化隔氧效应起着重要作用。

| Abstract: | Water mist fire suppression system is an attractive candidate ad the Halon replacement,and much research has been made on interaction of water mists with fires.In this paper,the interaction of water mists with fires in a confined space was studied with the advanced material heat release rate meter,and the conclusion was drawn that water mists have effect on fires in a confined space through displacement oxygen,evaporation cooling and heat rediation attenuation,To suppress fires in the confined space,displacement oxygen plays the very inportant role. |
