地源热泵地下垂直埋管换热器的试验研究

介绍了地源热泵的发展意义及前景， 参照国外地下埋管换热器岩土温度场的求解方法，采用线源理论及热阻网络分析方法建立了传热模型，提出了采用计算法确定大地初始温度并与实测值进行了对比。在建设的垂直埋管换热器试验装置上进行了单管、三管串联运行试验，为开发地源热泵技术提供了可供参考的数据。

Experimental Research on Vertical Buried Tube Typeof Underground Exchanger for Ground-Source Heat Pump

This paper introduces the importance of developing the Ground-Source Heat pump and describes the prospects of it.with the method used abroad to acquire the temperature profiles within surrounding soil of the underground heat exchanger with buried tubes, in this paper the line heat source theory and thermal resistance network analysis method were used to set up the heat transfer model.The original temperature of the ground is determined by calculation and is compared with test results. Experiments of running single tube and running three series connection tubes are carried out on the built underground exchangers of vertical buried tube type.And the data which can provide reference for the Ground-Soure Heat pump technique are acquired.
