基于ISO 9705标准火灾实验室,通过FDS设置额定的火源功率以及起火点,对比普通下垂型喷头与边墙型喷头的灭火效果、热释放速率、经济效益,综合分析得出虽然边墙型喷头有着更好的经济效益,但是就灭火安全来说普通下垂型喷头优于边墙型喷头,边墙型喷头替换普通下垂型喷头一定要谨慎。
Based on the ISO 9705 standard fire laboratory, set the rated fire source power and fire point by FDS, compared the fire extinguishing effect, heat release rate and economic benefits of ordinary drooping type nozzle and side wall type nozzle, the comprehensive analysis shows that although the sidewall type nozzle Has a better economic efficiency, but the general safety of fire extinguishing nozzle is better than the wall-type nozzle, wall-type nozzle to replace the ordinary pendent nozzle must be cautious.
