摘要
高压细水雾自动灭火装置是综合管廊消防设施中较为新颖的自动灭火装置。由于其实际工程案例较少,应用过程中遇到了很多问题。文中根据《细水雾系统技术规范》,并结合实际工程设计经验,重点探讨高压细水雾设计中设计参数选取和设备布置原则等问题。应引入适合综合管廊的灭火方式,设计原则应结合管廊内保护对象的性质和蔓延属性。
High-pressure water mist fire extinguishing systems are novel fire-fighting facilities in utility tunnels.Because of lack of actual project cases,many problems encounter in applicaction.Selection of design parameters and equipment layout principles are discussed according to the codes and practical design experience.New extinguishing mode should be introduced into the systems of utility tunnels.Beside,design principle should aim at the nature of protected object and features of fire spread in utility tunnels.
