- Title:
- Feasibility of Preaction Sprinkler System Applied in High and Large Space Buildings
- Keywords:
- preaction sprinkler system; high and large space buildings; single chain; fire detector; water filling time; buoyancy plume
- 摘要:
- 根据《自动喷水灭火系统设计规范》（GB 50084—2017）及《自动喷水灭火系统设计手册》对预作用系统的定义、公安部天津消防研究所的喷头开启时间试验、火灾报警系统的选择进行了分析，对预作用自动喷水灭火系统在高大空间中控制火灾及灭火的可行性进行了验证。结果表明，GB 50084—2017中表5.0.2民用建筑和厂房高大空间场所在采用图像型火焰探测器及充水时间合理取值（建议充水时间ΔT<90 s）的前提下，可以采用单连锁预作用喷水灭火系统。
- Abstract:
- This paper analyzed the definition of preaction system, the sprinkler opening time test of Tianjin Fire Research Institute of the Ministry of Public Security, and the selection of fire alarm system based on Code for Design of Sprinkler Systems (GB 50084-2017) and Manual for Design of Sprinkler Systems, and verified the feasibility of preaction automatic sprinkler system for fire control and extinguishing in high and large space buildings. A single chain preaction sprinkler system could be used on the premise that image type flame detectors were equipped and a reasonable water filling time was set (the recommended value is less than 90 s) in civil buildings and factories with large spaces according to table 5.0.2 specified in GB 50084-2017.
