竖直地埋管换热器换热性能及经济分析

The heat transfer performance and economic analysis of vertical ground heat exchanger

针对土壤源热泵系统,建立单U型、双U型及W型埋管实验系统,进而对不同竖直地埋管换热器的换热性能及阻力进行分析比较,同时探讨了不同型式的埋管在不同流量下经济成本随时间的变化情况,并确定各自的最佳流量,从换热性能和经济成本两方面对不同竖直地埋管换热器进行综合评价。

In view of soil heat pump system,this paper establishment of single U,double U and W buried pipe experiment system,then analyzed and compared the heat transfer performance and resistance of different vertical ground heat exchanger,through the discussion on the change situation of economic costs with the time of different forms of buried pipe under different traffic,and determined its own best traffic,from heat transfer performance and economic cost two aspects evaluated different vertical ground heat exchanger.
