摘要:
地源热泵系统换热效果所受到的影响因素很多，地源热泵换热量的大小是反映系统换热性能优劣的重要参数．通过CFD数值模拟软件分析了单U地埋管保温、不保温和保温长度不同及不同流量下的换热情况，得出了地埋管的单位井深换热量是随着流量的增大而增大，保温地埋管换热能力要高于非保温管，且保温层深度要适宜的结论．同时，结合实际工程实测数据进行对比分析，验证了模型及数值模拟结果的正确性．
Abstract:
There are many factors affecting the heat transfer effects for ground source heat pump systems . The heat exchange amount of ground source heat pump(GSHP) is an important index to reflect heat transfer performance. By using CFD software, the heat exchange capability of single-U buried pipe under different flow rate and the rmal insulation conditions is analyzed. A conclusion is derived there from that the heat exchange amount per unit depth of well increases with the flow rate, the heat exchange capability of thermal insulation buried pipe surpasses non-thermal insulation pipe and the depth of Insulation pipe should be appropriately chosen. Furthermore, the validity of the model and simulation result is verified through comparison with project measured data.
