在水电站采暖通风的多种类型中,利用坝体廊道对空气进行冷却,节能效果显著。在水电站通风空调设计中,冷却效果的准确计算是方案确定的依据。但传统设计计算方法没有考虑坝体的动态蓄热作用。采用有限元分析方法,在夏季工况下用ANSYS对空气与坝体的热交换进行数值模拟。计算结果表明:考虑坝体动态蓄热作用的有限元分析方法在水电站通风空调设计中有重要的理论和实际意义。
In many types of heating and ventilation of hydropower stations, the use of dam corridor to cool the air, energy-saving effect is remarkable. In the design of ventilation and air conditioning of hydropower station, the accurate calculation of the cooling effect is the basis for determining the scheme. However, the traditional design and calculation methods do not consider the dynamic thermal storage effect of the dam. The finite element analysis method is used to simulate the heat exchange between air and dam under the condition of summer. The calculation results show that the finite element analysis method considering dynamic thermal storage of dam has important theoretical and practical significance in the design of ventilation and air conditioning of hydropower station.
