高压细水雾灭火系统在上海市档案馆新馆中的应用

Application of high pressure water mist fire extinguishing system in the new Shanghai Archives

结合上海市档案馆新馆的工程特点,从灭火效果、环境影响、建筑设计、工程经济、运营维护等方面对比高压细水雾系统和气体灭火系统在普通纸质档案库房消防系统应用的优缺点,分析高压细水雾灭火系统的技术优越性。重点阐述结合档案库房建筑布置,进行防护区和防护分区合理划分的原则和技术要点,提出以单间档案库房作为防护分区,并以满足系统响应时间的管道长度来确定防护区规模的设计思路。

Combined with the engineering characteristics of the new archives of Shanghai,the advantages and disadvantages of the application of water mist system and gas fire extinguishing system in the ordinary paper archives warehouse are compared from the aspects of fire extinguishing effect,environmental impact,architectural design,engineering economy,operation and maintenance,and the technical advantages of the application of high-pressure water mist fire extinguishing system are analyzed.This paper focuses on the principle and technical points of reasonable division of enclosures in combination with the layout of archives warehouse building,and puts forward the design idea of taking single archives warehouse as protection zone and determining the scale of protection zone with the length of pipeline meeting the system response time.
