摘 要:通过HHHT抽水蓄能电站地下主厂房1:20缩尺模型来研究其母线层气流组织分布。在56m3/h及112m3/h的两种风量下,分别选择5种送风口方案1~5,对母线层工作区温度场及速度场进行测试。未封闭吊物孔、未安装接力风机时的温度分布标准差最大值为0.95,最小值为0.42;封闭吊物孔、安装接力风机后的温度分布标?准差最大值为0.35,最小值为0.08。研究表明,封闭吊物孔、安装接力风机加强了母线层工作区气流组织分布的均匀性,双排对称布置送风口(方案5)为最佳送风口方案。研究结果为HHHT及相关电站地下厂房复杂气流的优化组织设计提供了参考依据。The HHHT pumped-storage underground powerhouse 1/20 reduced-scale model was established conducted to investigate the air distribution in busbar layer. The temperature field and velocity field of occupant zones of busbar layer was tested with two kinds of different air rate for 56 m^3/h and 112 m^3/h, and 5 kinds of air supply diffusers are measured. The standard deviation of temperature distribution was tested maximum value for 0.95 and minimum for 0.42 with open holes for installment, and without installation of relay fan. The standard deviation of temperature distribution was founded to be maximum value for 0.35 and minimum for 0.08 with closed holes for installment and installed relay fan. Studies have shown that closed holes and installed relay fan can enhance the air distribution uniformity in the busbar layer, double row symmetrical layout (5) supply scheme for the best air diffuser. The experimental result HHHT about underground powerhouse is helpful in designing air distribution in large spaces.
