吊顶形式及室内喷头位置对玻喷系统响应时间的影响

The Effect of Sprinklers under Different Ceiling Forms of Shops on the Response Time of Glass-Water Sprinkle System

针对室内步行街临街商铺多数采用"玻璃+水喷淋"方式进行防火分隔,如商铺内喷头布置不当可能会影响玻喷系统的及时响应。在专题调研的基础上,采用FDS6模拟不同吊顶形式下商铺自动喷水灭火系统与玻喷系统同时共存的场景,探寻了不同吊顶形式下商铺自动喷水灭火系统对玻喷系统的影响规律,研究表明:商铺自动喷水灭火系统的设置和吊顶形式均会对玻喷系统响应造成影响,建议工程中玻喷系统的设计应考虑商铺自动喷水灭火系统和吊顶形式的影响。

Most shops along sides of indoor commercial pedestrian mall use the method of ＂glass ＋ water spray ＂（ hereinafter referred to as Glass-Water Sprinkle System） as fire compartment,while improperly arranged, sprinklers in shop may affect the timely response of this sprinkle system. Based on survey results to present situation,the authors employed FDS6 to simulate the co-existence scenario of automatic sprinkler system and Glass-Water Sprinkle System under different ceiling forms,and explored the influence pattern of automatic sprinkler system on Glass-Water Sprinkle System under different ceiling forms. The research showed that both sprinkler system layout and ceiling forms will affect the response of the Glass-Water Sprinkle System. It is suggested that the design of this system in the project should consider the influence of automatic sprinkler system and the ceiling forms.
