喷淋的冷却作用对自然排烟影响的实验研究

Experimental studies on effect of smoke venting combined with sprinkler cooling

通过实验,研究了火源功率一定的情况下,喷淋的冷却作用对自然排烟造成的影响。针对喷淋前后烟气层温度和自然排烟速度进行了分析,结果表明,喷淋的冷却作用会对烟气层温度、自然排烟速度产生较大的影响,对建筑工程进行自然排烟设计时要充分考虑喷淋对排烟的影响。

A series of experiments was conducted to study the influence of sprinkler cooling on natural smoke exhaust under stable fire size. Analyzing smoke temperature and natural smoke exhaust speed under different sprinkler pressure. Results showed th.at sprinkler spray have a great influence on smoke temperature and natural smoke exhaust speed, so sprinkler cooling should be considered in smoke venting design.
