摘要
建立了区分岩土和回填区的地埋管换热器分区数值分析模型。采用数值分析手段分析了回填材料导热系数在不同地埋管间距、不同管径和不同埋管类型中的影响规律,对回填材料在地源热泵系统中的实际工程应用具有指导意义。
This paper establishes a numerical analysis model for the geothermal heat exchanger partition of geotechnical and backfilling areas.The influence of thermal conductivity of backfill materials on different pipe spacings, different pipe diameters and different buried pipe types was analyzed by numerical analysis. This has guiding significance for the practical engineering application of backfill materials in ground source heat pump system.
