上海地区地源热泵工程地温场特征试验研究
Experimental study of ground temperature field characteristics surrounding GSHP system in Shanghai
摘要：
结合实际地源热泵工程，建立了地温场监测试验场，对埋管中心区域、边缘区域和U形管壁附近地温，以及地埋管换热器水温、流量等运行参数进行了监测，了解了系统全年累计吸排热量和系统性能，重点分析了换热区地温随时间、竖向和径向的分布规律及总体地温变化趋势。

Abstract：
Combined with a ground-source heat pump project, sets up a monitoring testing field of ground temperature around ground heat exchanger, and monitors ground temperature in centers and peripheries of heat exchanging field, ground temperature near U-shape pipe wall, water temperature and flux in U-shape pipe and so on. Obtains the total quantity of heat absorption from ground and heat release to ground and COP, and emphatically analyses the distribution rules of the ground temperature around heat exchanger with time, depth and radial direction and the total changing trend.
