三峡电站主厂房分层空调冬季工况模型试验

Analysis of the Model Experiment of Stratificated Air-Conditioning in Winter Condition in the Powerhouse of Three-Gorges Hydropower Station

建立三峡电站主厂房发电机层标准机组段分层空调的试验模型。在确保分层效果的基础上 ,对该模型冬季供暖工况进行温度场和速度场的实测 ,就 2种不同的送风口型式及同一送风口型式 3种不同送风方式对模型工作区空气分布特性的影响作了初步分析 ,在试验条件下确定出了最佳的送风口型式及送风方式 ;同时 ,在送风口型式及送风方式不变的情况下 ,改变送风温度以观测其对工作区温度场的影响 ,从而为后续的分层空调模型试验提供了必要的技术数据 。

The model experiment of stratificated air conditioning in the powerhowse of Three Gorges Hydropower Station is briefly precented. On the basis of ensuring the effect of air conditioning, the influences of two types of outlet, three modes of air supply under the same outlet type on air distribution performance in occupied area was emphatically analyzed arrowd the measured data of occupied area's temperature and velocity in winter condition,and the best outtet type and air supply mode is obtained. By changing air supply temperature,its influence on the occupiod area's temperature is also analyzed,thus,some wecessary techincal data for follow enperiments and some condusions for reference have been draw.
