摘　　要：为研究喷头安装高度对自动喷水灭火系统控火性能的影响,分别在安装高度为3m和8m的情况下,选取目前应用最为广泛的标准喷头开展对比试验,从动作时间、动作个数、动作温度以及货物烧损量等方面进行对比分析。结果显示,在2种安装高度下,喷头均能有效控火,但安装高度提升不仅造成喷头动作时间延迟,还使得喷头动作个数、货物烧损量等明显增加。In order to study the influence of height on the sprinkler system extinguishing performance,comparative tests were conducted at the height of 3 m and 8 m,and using the most widely used standard sprinkler.The operation time,number of sprinklers active,operating temperature and burning cargo were compared and analyzed.Results showed that the fire can be extinguished effectively under 2 installation height,but when the height is bigger,the operation time was delayed,the number of sprinklers active increased,and the burning cargo increased too.

关 键 词：自动喷水灭火系统 安装高度 控火性能 动作时间
