【摘要】 以四川省绵阳市某新能源改造项目为基础,对其进行热响应测试。建立与实际工况相同的三维分层换热模型,用试验数据与数值分析数据对比,验证模型的精度。分别研究渗流在水平方向与垂直方向下的渗流速度、入口速度、孔隙率及渗流方向对竖直单U型地埋管换热器换热性能的影响。更多还原

【Abstract】 The thermal response of a newenergy transformation project is tested in Mianyang City,Sichuan Province. The three-dimensional layered heat transfer model with the same working condition is established,and the accuracy of the model is verified by comparing the experimental data with the numerical analysis data. The effects of seepage velocity,inlet velocity,porosity and seepage direction on the heat transfer performance of vertical single U-type buried pipe heat exchangers were studied respectively in the horizontal and vertical directions.更多还原
