摘要
采用计算流体力学软件对土壤不同含水率、不同渗流速度下垂直U型地埋管换热器换热过程和地埋管群之间的热干扰进行数值模拟,给出了地埋管逐时出水温度,分析了不同含水率、渗流速度下地埋管换热器换热量变化规律及地埋管之间的相互热干扰。
Numerical simulations of the heat exchange process of the vertical U type ground heat exchanger in different moisture content of soil and different water seepage velocity and the thermal interference between the buried pipes were conducted using the computational fluid dynamics software, the outlet water temperature of the ground heat exchanger hour by hour was given, and the heat transfer amount change rules of heat exchanger in different moisture content of soil and different water seepage velocity and the thermal interference between buried pipes were analyzed.
