摘要

本文通过实验探讨了不同入流水量和温度对地下热泵换热性能的影响，定义了衡量地下换热器性能的两个重要参数:能效系数和换热利用时间。实验结果表明，无论是冬季工况还是夏季工况，地埋管进口水温的变化都不会影响地埋管能效系数随时间变化的趋势，降低水速有利于提高地埋管能效，提高主机运行效率。

The Influence of Different Inflow Water Rate and Temperature on Heat Exchange Performance of Underground Heat Pump

in the paper, the influence of different inflow water rate and temperature on heat exchange performance of underground heat pump were discussed by experiment, two vital parameters was defined to measure the properties of ground heat exchanger: Energy Efficiency Coefficient and Heat Exchange Utility Time. The experimental results showed that whether in the winter or summer working condition, and the change of water temperature of buried tube inlet could not affect the trend of Energy Efficiency Coefficient changing with time, and reducing water velocity will help to enhance energy efficiency of buried tube, and improve the host operating efficiency.
