摘　　要：地源热泵热物性参数一般通过恒热流法热响应及恒温法冷响应测试得到。上海的浅层地温能具有赋存条件和开发前景,是地源热泵系统的热量来源。通过实测地下岩土体平均温度沿深度的分布,分析地源热泵测试制热过程对周围土体温度场的影响,对比分析不同地层条件、水文地质条件对地源热泵测试结果的影响,同时探讨了单U、双U型不同地埋管方式的换热性能参数及经济性对比,对指导地热资源有效利用具有一定指导作用。The thermal physical parameters of a ground source heat pump are generally measured using the constant heat flow thermal response and the constant temperature cold response tests.By measuring the distribution of the average temperature along the depth of the underground rock and soil,the influence of the ground source heat pump test process on the surrounding soil temperature field is analyzed.The influences of different formation and hydrogeological conditions on the geothermal heat pump test results are analyzed.Further,heat transfer performance parameters are discussed and analyzed and an economic comparison of single U and double U type buried pipes is done,to guide the designing of systems for the utilization of geothermal resources.
