建立了根据地温分布确定地下水流动特性的简化数学模型。针对一个实际工程钻孔进行了地温分布测量,并测试了局部地下水渗流条件下埋地换热器的传热性能。结果表明,上述理论模型具有较好的预测精度。在该文实验条件下,地下水渗流对埋地换热器的传热性能具有明显的强化作用,埋地换热器的换热量平均提高11.35%。 A simplified mathematical model was established to determine the groundwater flow characteristics based on the geothermy distribution. The geothermal distribution of a real engineering borehole was measured and the heat transfer performance of the buried heat exchanger under local groundwater seepage was tested. The results show that the above theoretical model has a good prediction accuracy. Under the experimental conditions, groundwater seepage has a significant strengthening effect on the heat transfer performance of the buried heat exchanger, and the heat exchange of the buried heat exchanger increases by 11.35% on average.
