介绍了根据浅埋竖管换热器地热源热泵冬季测试结果 ,在夏季试验中对试验装置及实验方法的改进 ,测试了夏季定水量 ( 63天 )的运行效果和变水量运行时各性能指标的变化。采用系统能量平衡结合热传导方程建立的地下竖埋套管管群换热器传热模型和过渡季大地温度场模拟 ,与实测值吻合较好 This paper introduces the winter test results of geothermal heat pump with shallow buried pipe heat exchanger, the improvement of the test equipment and experimental method in summer test, the running effect of constant water volume in summer (63 days) and various performance indexes The change. The heat transfer model of underground vertical buried casing tube group heat exchanger and the earth temperature field simulation of transitional season established by the system energy balance and heat conduction equation are in good agreement with the measured values
