预作用自动喷水灭火系统的设计

Design of sprinkler system in a university library

介绍了几种常见的自动喷水灭火系统,对预作用自动喷水灭火系统的基本特点和工作原理进行了阐述,指出控制系统管网的充水时间是保证预作用系统正常运行的关键.为了满足沈阳建筑工程学院新校区图书馆的不同使用功能和建筑专业划分防火分区的需要,设置了两种自动喷水灭火系统.并在该建筑地下室的藏书库等部位采用预作用系统,地上中庭部分采用湿式系统,并且根据危险等级的不同和系统的布置形式确定了合理的设计流量.虽然地下室的危险等级比中庭高,但是由于中庭的喷头布置紧密,其设计水量却比地下室大,最后取中庭的设计水量为29 0L/s作为系统的设计流量.

Some kinds of sprinkler system are introduced,and the fundamental characteristic and the operating principles of preact system are elaborated.It is demonstrated that controlling the waterfilling time of pipe network of the system is the key to guaranteeing the normal function of the system.Two kinds of fireextinguishing facilities,including wet pipe system in the winding corridor and preact system in the basement,are installed in order to meet the needs of various use functions and different fire areas of the Library of Shenyang Architecture and Civil Engineering University.A reasonable design flow is determined according to the different danger levels and the arrangement of the system.Finally the maximum design flow -290L/s is taken as the design flow of the system.
