贯流式水电站厂房设置通风采光天井初探

高变幅尾水位的中小型贯流式水电站,副厂房最高尾水位以下内部空间近乎封闭,厂房自然通风与采光条件较差。设置天井是电站副厂房实现自然通风与采光的一种途径和一种传统节能技术。初步分析了下游洪水位变幅较大等环境条件下,贯流式水电站副厂房设置自然通风采光天井的空间条件及其技术性和经济性,讨论了天井布置原则和空间尺度与形态处理,给出设计实例并初步评价了天井通风采光的效果。

Discussion on layout of light-court for lighting and ventilating for powerhouse of hydropower station with through-flow turbines

For the medium and small sized hydropower stations equipped with through-flow turbines under the condition of higher fluctuation range of the tail-water levels, the internal space of the auxiliary powerhouse under the maximum tail-water level is almost closed with poor ventilating and lighting condition. The layout of light-court is a traditional energy-saving technique and a common way to realize the natural ventilating and lighting for the auxiliary powerhouse. The spatial condition and both the technical and economic feasibilities for the layout of the light-court for the auxiliary powerhouse under the condition of higher fluctuation of the flood level downstream is basically analyzed; in which the principles of the layout and both the spatial dimension and configuration are discussed, and then a actual design case is given with the preliminary evaluation on the ventilating and lighting effect of the light-court.
