针对地下水源热泵抽水井与回灌井布局模式对地下温度场的影响,通过建立地下水流与温度的耦合模型,从抽灌井布置间距及抽灌井数量角度模拟分析了不同布井模式下地下水温度的变化趋势和热贯通发生的基本特性。结果表明,同类井间距对热贯通影响不显著,抽灌井间距对抽水温度及热贯通时间影响较大;从热贯通发生时间来看,抽灌井数量越多热贯通发生的时间越延迟,但从温度偏离度角度分析,系统长期运行后抽灌井数量对抽水温度偏离度影响不显著。
Aiming at the influence of groundwater source heat pump pumping well and injection well layout pattern on underground temperature field, a groundwater flow and temperature coupling model was established to simulate the underground water distribution under different well patterns The trend of temperature and the basic characteristics of hot through. The results show that the distance between the wells of the same type has no significant effect on the heat penetration, and the interval between pumping wells and wells has a great influence on the pumping temperature and the heat penetration time. From the time of heat penetration, the number of pumping wells is more delayed, However, from the perspective of temperature deviation, the number of pumping wells after the long-term operation of the system has no significant effect on the deviation of pumping temperature.
