| 中文摘要: |
| 文章以典型软垫家具——单人软垫沙发为研究对象,对全尺寸多功能热释放速率标准燃烧室ISO9705(3.6m×2.4 m×2.4 m)加装水灭火系统,采用ZSTP15型水喷淋喷头对单人沙发燃烧行为进行全尺寸实验研究。测量并分析总结了在0 L/min、35.8 L/min、50.6 L/min、62.0 L/min四种不同流量水喷淋作用下沙发燃烧的热释放速率、顶棚烟气温度和CO、CO2生成速率等火灾特性参数随时间变化的规律,结果表明,由于水的冷却和隔氧作用,水喷淋的施加对室内沙发燃烧性能有显著影响,且随着流量的改变其燃烧过程呈现不同的变化趋势。 |

| In this paper,single upholstered sofa and the ZSTP15 sprinkler have been chosen to perform full scale experiments in the refitted ISO9705 Room which was jointed to a water sprinkler system.Parameters such as heat release rate of sofa,temperature fields of ceiling and CO/CO2 production rate for different water spray flow rates(0 L/min、35.8 L/min、50.6 L/min、62.0 L/min) have been measured.By analyzing these parameters,the relationships between them were discussed.Results indicated that the presence of water spray results in great effects on the burning behavior of sofa,and the extinguishment process varies with different water flow rates. |
