摘　　要：通过解析解模型来对多钻孔地埋管换热器的传热进行建模,并将传热模型计算得到的理论地埋管换热器进出口平均水温,与实际测试的地埋管换热器进出口平均水温进行比较,分析出多钻孔地埋管热泵传热数学模型在实际工程应用中是足够精确的。In this paper, the heat transfer mathematical model has been established for the heat pump heat exchanger. And the average water temperature between the import and export by this heat transfer mathematical model has been compared with that by actual measurements, then it has been analyzed that it is sufficiently accurate to use this heat transfer mathematical model to actual measurements.
