摘　　要：针对地源热泵系统在夏热冬暖地区长期运行可能引起的地下温度场热量累积问题,提出地源热泵系统通过制冷、停机和制热3种工况的交替运行这一解决措施。采用有限长线热源模型,并利用迭加原理,对钻孔不同深度处、距离钻孔中心不同半径处及不同运行策略下U形埋管地下换热器周围温度场的变化进行研究。对指导地源热泵系统的工程运用具有实用价值。For heat accumulation in underground temperature field caused by the ground source heat pump system being in long-term operation in hot summer and warm winter zone,puts forward the solution that the ground source heat pump system is operated alternately under cooling,shut-down and heating conditions.Using the limited long-term heat source,and superposition principle,studies the underground temperature field around U-tube heat exchanger on different drilling depth,distance from the drilling center and operation strategies.The result has practical value for guiding engineering application of the ground source heat pump system.
