三峡电厂发电机层夏季分层空调负荷特性与过程设计分析

Analysis on the Load Characteristics and Process Design of Laminated Air-conditioning in Summer in the Powerhouse of Sanxia Hydropower Station

针对三峡电站主厂房设计的若干特殊性, 围绕发电机层夏季分层空调负荷特性与过程设计问题进行分析和探讨:在发电机层空调负荷核算基础上,根据不同核算结果进行其分层空调负荷特性分析以及节能效益乃至核算方法的评价; 进一步以发电机层标准机组段下游侧为代表, 对其空调过程设计中的设计工况与系统设计冷负荷确定等问题进行对比与分析,从而为该电站主厂房发电机层空调工程设计提供科学依据。

Considering the particularities in the powerhouse design of Sanxia Hydropower Station, the load characteristics and process design of laminated air-conditioning at the generator level in summer have been analyzed and discussed. Several methods of load calculation have been analyzed. Based on the results of calculation by these methods, the load characteristics and energy saving benefits have been discussed. Taking a normal section at generator level for an example, the design condition and refrigeration demand have been dissected, thus providing some experiences to this or other project.
