摘要:
将地埋管周围同物性岩土分层,模拟地源热泵地埋管夏季制冷条件下各岩土层非稳态传热过程；与一般传热模型模拟结果对比,分析钻孔外岩土区域温度场热作用特性.利用多层岩土传热模型,研究了距钻孔一定距离处岩土温度场分布随运行时间的变化规律,以及进口流体速度、土壤热物参数对地埋管周围岩土温度场分布的影响.计算结果可为地源热泵地埋管换热器的动态模拟、优化设计提供参考.
Abstract:
Layering buried tube around with physical geotechnical properties, simulate ground source heat pump(GSHP) buried tube unsteady heat transfer process, which is on summer refrigeration conditions. With general heat transfer model simulation results contrast, analysis drilling outside temperature field hot effect characteristic. Use multilayer geotechnical heat transfer model and a certain distance away from drilling in geotechnical temperature field distribution with running time change rule, and importing flow velocity, soil thermal physical parameters on buried tube around the influence of geotechnical temperature field distribution. Calculation results provide ground source heat pump ground heat exchanger dynamic simulation, optimization design for reference.
