摘要
建立了热渗耦合作用下的土壤传热数学模型。针对单U形地埋管地源热泵系统,分析了在不同地下水渗流速度和土壤热物性条件下,地下水渗流对土壤温度场的影响;针对管群地埋管地源热泵系统,进行了全年跨季节土壤蓄热、取热运行工况模拟,得到一个周期内不同工况结束时的土壤温度场分布。
Establishes a mathematical model of soil heat transfer under heat transfer and groundwater seepage.For the single U-tube ground-source heat pump system,analyses the influence of the groundwater seepage on the soil temperature field under the condition of different groundwater seepage velocities and soil thermo-physical properties.For the pipe-group ground-source heat pump system,simulates the annual operating conditions of seasonal soil thermal storage and release,and obtains the distribution of soil temperature field at the end of different operating conditions in a cycle.
