为确保地源热泵系统能够得到合理利用，本文在TOUGH2平台基础上建立了垂直U形地埋管三维精细热渗耦合数值模型，对系统的全年运行特性进行分析，针对冬夏负荷不平衡特点，利用TOUGH2-MP/EOS3数值代码，分析讨论系统运行过程中不同单位井深换热量对土壤温度及土壤温度恢复的影响。模拟结果表明利用TOUGH2数值模拟方法研究地埋管热渗耦合问题具有一定的优势和可行性。

To ensure that a ground source heat pump can be used effectively, basic methods for conducting numerical simulations of vertical U-shape buried pipe are described based on TOUGH2 code. The operating characteristics of the system are analyzed throughout the year according to the characteristics of heat load imbalance in winter and summer. Heat exchange quantities per unit wel depth that affect soil temperature and recovery are discussed. This study also shows that numerical simulation methods can be used to study geothermal heat exchange under coupled thermal conduction and groundwater advection.
