摘要
在解读相关规范基础上,分析排烟口朝向对气流的影响。以某扁平商业空间为例,利用FDS模拟排烟口朝向对排烟效果的影响。结果表明,在同样的排烟管道条件下,排烟效果优劣的顺序依次为:排烟口朝上、排烟口侧向、排烟口朝下。
Based on the understanding of reletive standards,the influence of the smoke vent orientation to airflow was analyzed.Taking a commercial flat space as an example,the influence of the smoke vent orientation to smoke evacuation was simulated by FDS.Results showed that,given the same vent-pipe condition,the merits of the order of the smoke vent orientation is： upwards,lateral,downwards.
