通过对地下混凝土储热桩的储热研究,选用单U型埋管换热器,建立地下混凝土储热桩埋管换热器周围温度场模拟分析所用的物理模型和数学模型。通过模拟仿真,研究了储热桩体温度受埋管半径、埋管流量等参数变化的影响,并总结出受这些因素影响后储热桩内换热器周围混凝土温度场的变化趋势,为以后的实验研究提供了参考依据。
通過對地下混凝土儲熱樁的儲熱研究,選用單U型埋管換熱器,建立地下混凝土儲熱樁埋管換熱器週圍溫度場模擬分析所用的物理模型和數學模型。通過模擬倣真,研究瞭儲熱樁體溫度受埋管半徑、埋管流量等參數變化的影響,併總結齣受這些因素影響後儲熱樁內換熱器週圍混凝土溫度場的變化趨勢,為以後的實驗研究提供瞭參攷依據。

Based on the research on the thermal storage of the underground concrete heat storage pile,and with the help of the single U-shaped heat exchanger,we establish the physical and mathematical models to make analysis of the temperature field around the underground concrete heat storage pipes heat exchanger. Then,through the simulation,we study the variation of heat storage pile body temperature with the pipe radi-us,buried pipe flow and other parameters,and sums up the trends of the concrete temperature field around the heat storage pile,which provide a reference for the future experimental research.
