摘要
针对地源热泵垂直U型埋地换热器的传热特性,建立了换热器及周围土壤温度场的数学物理模型,模拟计算分析了单钻孔垂直U型埋地换热器短期运行工况下系统运行时间和不同灌浆材料对埋管周围土壤温度场的影响。研究结论可为合理设计埋管换热器提供参考。
The heat transfer model of underground vertical buried tube heat exchanger was built with considering the heat transfer characteristics of U-tubes ground heat exchanger of ground-source heat pump.Then influences of the system operating time and borehole＇s backfill material on the soil temperature field were analyzed.The research results may provide a guidance in the design of ground coupled heat pump systems.
