| 中文摘要: |
| 为了对烟气控制进行研究,中国科学技术大学大空间火灾实验厅安装了三台大功率固定转速风机和一台变频调速风机 ,但风机的实际流率和变速风机流率与频率的关系没有通过系统地测定。该研究采用三种实验方案测量了定速风机的排烟速率以及变速风机排烟速率与频率的关系 ,得到定速风机的排烟速率为 13.5m3/s ,比风机出厂流率稍小;变速风机流率与频率之间关系为:Q=0.18+0.2 68f. |

| To study smoke control, the large space fire experiment hall of university of science and technology of China was equipped with three fixed speed fans and an alterable speed fan. But the actual flux of the fans and the relationship between flux and frequency of alterable speed fan have not been mensurated systematacally. The author determined the actual flux of the fans by three ways and gave the relationship between flux and frequency of alterable speed fan. That is 13.5m 3/s of fixed speed fan, and Q=0.18+0.268f between the flux and frequency. |
