垂直地埋管换热器热响应测试与分析

摘要

This paper introduces the thermal transmiting model of vertical ground heat exchanger, tests and analyzes heat response of vertical ground heat exchanger of an international convention center in Changshu city with constant temperature method. Through collecting and analyzing experimental data, it obtains the heat transfer capability of single hole and ground thermal conductivity and other parameters, which has provided basic data for the design and construction of ground source heat pump.%介绍了垂直埋管地下换热器的传热模型,并对常熟市某国际会议中心项目垂直地埋管换热系统利用恒温法进行了热响应测试和分析。通过整理和分析试验数据,获得了单孔的换热能力和地层的导热系数等参数,为地源热泵设计和施工提供了基础资料。
