本文对消防的细水雾灭火系统的定义和作用机理进行了阐述,介绍了应用较广泛的单相流泵组式细水雾灭火系统与双相流瓶组式细水雾灭火系统的工作原理,并对细水雾灭火系统的设计进行了介绍,以对细水雾灭火系统进行全面了解,推动细水雾灭火系统研究与设计的发展。 This paper described the definition and mechanism of water mist fire protection system. The principle of single-phase pump type water mist fire protection system and double-phase cylinder type water mist fire protection system is introduced. Furthermore, the basic design process of the system is illustrated to make a comprehensive introduction of water mist fire protection system, therefore, to promote the development of research and design to the system.
