摘　　要：通过分析地埋管换热器的传热特性,建立了地源热泵地埋管换热器数学物理模型,利用FLUENT软件对换热器的传热相干性进行了数值模拟,在此基础上,通过对地埋管换热器传热性能实测与夏季非连续运行工况的模拟结果比较,得到不同埋管间距周围的土壤温度沿径向的变化规律及地埋管传热相干性的影响规律。With the establishment of mathematical and physical model and numerical simulation of vertical tube by FLUENT, characteris- tics of buried tube heat exchanger of ground source heat pump （GSHP） was analyzed. Based on this information, combined with the simu- lation and measurement of summer discontinuous operation results, the law of different buried tube space on the radial variation of soil temperature and coherent effects of buried tubes heat transfer were got.
