在试验研究中考察了送风速度和热源发热量对工作区气流组织的影响。试验结果显示,主变室的热源发热量从107kW增大到178kW时,气流流场变化不大;送风速度从1.8m/s增大到3.3m/s时,气流流场存在较大变化。表明对于有集中热源且采用下送上回气流组织的房间,机械力较热浮升力对气流流场有更大的主导作用。
In the experimental study, the influence of air supply speed and the heat generated by the heat source on the airflow organization in the work area was examined. The test results show that when the heat source heat of main transformer room increases from 107kW to 178kW, the airflow field does not change much; when the supply air speed increases from 1.8m/s to 3.3m/s, the airflow field has a great change. . It shows that for a room with concentrated heat source and using the next-to-last air flow organization, the mechanical force has a greater leading effect on the air flow field than the hot buoyancy.
