地下水电站的送风方案——模型实验研究

地下水电站厂房的送风量很大。本文用相似模型试验研究了三种不占有用空间的气流组织方式。试验结果表明,从大门送风,远离大门处的热环境不良。从端墙送风,工作区某些地点风速太高。这可通过减低送风风速或用辅助条缝风口解决。从吊顶送风的效果令人满意。推荐在每台发电机组段的吊顶上只布置1个风口。

AIR DISTRIBUTION IN UNDERGROUND WATER POWERHOUSES

The volume of supply air of an underground water powerhouse is very large. Three methods of air distribution that do not occupy a lot of useful space, these methods are studied by scale model tests in this paper. The results of the tests show that the thermal environment quality at the far end away from the gate is poor if air is supplied from the gate. The velocity may be too high at some points in occupied zone if air is supplied from an end wall. This problem can be solved by reducing the supply air velocity or using an auxiliary slot. The effect of supplying air from the ceiling is satisfactory. The arrangement of one inlet under the ceiling for each generator's zone is recommended.
