摘　　要：展厅类场所展示有珍贵的文物资料,一旦发生火灾,将导致无可估量的损失。细水雾系统因具有灭火效率高、用水量少、水渍损失少、环境污染小等优点得到了广泛应用。《细水雾灭火系统技术规范》(GB 50898-2013)未对展厅类场所的系统选型、分区面积、喷雾强度等要求进行规定,因此对展厅类场所系统选型、分区设计思路进行分析,随后针对分区面积、喷雾强度、喷头型号及间距等进行试验验证。试验研究了不同火源位置、不同开口状态及不同火源形式下细水雾系统的灭火效果,结果表明:试验选用的细水雾分区面积、喷雾强度、喷头型号及间距满足灭火要求,相关分析及试验结果将作为中国某博物馆临展厅的设计依据。Fire in museum exhibition halls will lead to serious consequence because of the destruction of precious cultural relics.Water mist system is a high fire-fighting efficiency and low environmental pollution extinguish system has been widely used.However,specific requirements such as system selection,partition area,spray intensity for exhibition hall have not specified in Technical code for water mist fire extinguishing system(GB 50898-2013).This article firstly analyzes the system selection and partition design for exhibition hall,and then tests to determine the partition area,spray intensity,nozzle type and spacing.The fire extinguishing effect of the water mist system under different fire source positions,forms and opening states has been experimentally studied.The results shows that the partition area,spray intensity,nozzle type and spacing used in the water mist system satisfy the fire extinguishing requirements.The above analysis and test results are used as design basis for the museum exhibition hall.
