摘　　要：通过全尺寸消防水幕衰减火灾热辐射实验,分析了火灾空间烟气温度的分布,探讨了喷头流量和压力、设置高度、喷头类型和布置方式对水幕衰减辐射热能力的影响,获得了不同工况下消防水幕的隔热效率。在此基础上,结合消防水幕的工程设计参数,揭示了消防水幕在不同的设置条件下隔热效率的变化规律。研究结果对于优化消防水幕设计提高隔热效率具有理论和实践上的指导意义。By full size experiments on the attenuation of fire radiation due to the effect of fire water curtain, the distribution of fire smoke temperature was analyzed, and the factors, such as the flux, pressure, height, type, arrange of sprinkler that affect the fire radiation attenuation of fire water curtain, were discussed. The extinction efficiency of fire water curtain in various experimental conditions was obtained. Further, the variation of the extinction efficiency in various experiments was revealed. The results help optimize the fire water curtain design.
