摘　　要：研究了地埋管内水流量对埋管换热性能的影响,在全天连续运行情况下,选取3种不同水流量进行了分析。结果表明:地埋管换热器的单位井深换热量随水流速的增大而增大。连续运行模式下,第5天的单位井深换热量较第1天均减小。Three kinds of different water flow in pipe are selected to analyze the influence of water flow in pipe on the ground heat exchanger performance on the condition of the whole day operation of the heat pump. The re- sults show that the increase of heat transfer amount in per unit well depth of the ground heat exchanger leads to the increase of the water flow in pipe. In the condition of continual operating, the heat transfer amount in per unit well depth on the fifth day is less than that on the first day.
