摘要： 通过试验方式，获取3种模拟失效工况条件下自动喷水灭火系统的实际表现，分析比较系统设计工况条件下的预期控灭火效能，归纳不同失效工况对灭火效能的影响。试验结果表明：喷头溅水盘故障会造成洒水不均匀，使初期火势难以得到有效控制，导致喷头开启数量增加，有效控火效率降低约 40%。热敏感元件故障导致喷头动作的感应温度更高、动作响应时间更长，延误启动时间内火势迅速发展，喷水稳定后短期内难以达到正常状态下的火灾防控水平，导致控火效率降低约 25%。工作压力不足造成的影响最为严重，使得灭火效能降低约60%。

Abstract: Through experimental methods, obtain the actual performance of automatic sprinkler fire extinguishing systems under three simulated failure conditions, analyze and compare the expected fire extinguishing effectiveness under the system design conditions, and summarize the impact of different failure conditions on fire extinguishing effectiveness. The experimental results show：the sprinkler deflector failure will cause uneven water distribution and less effective control of early stage fire, so that the number of actuated sprinklers will increase to meet the fire control requirements, and the failure can result in about 40% reduction in fire extinguishing efficiency. The malfunction of the thermal sensitive element will lead to higher sprinkler operation temperature and longer response time, during which the fire develops too rapidly to be effectively controlled in the short term after the sprinkler actuation, and the malfunction can result in about 25% reduction in fire extinguishing efficiency. Furthermore insufficient working pressure will cause the most serious impact , which reduces the fire extinguishing efficiency by about 60%.
