摘 要: 在夏热冬暖的广东地区建立了U型地埋管地源热泵热水系统,建立了与实际U型地埋管换热器相一致的三维非稳态传热模型,通过Flnent软件仿真模拟与长期实验观察相结合的方法,研究该地区的地源热泵系统冬季模式与春秋模式下埋管周围土壤温度场分布与变化规律。为该地区地源热泵技术应用提供了相关的理论、实践参考。 A ground-coupled heat pump system(GCHPS) for hot water and an experimental system on the basis of it were established in Guangdong region where it is hot in summer and warm in winter.The three-dimensional non-steady-state heat transferring model is consis tent with the actual project,analyzing the heat distribution and changes of soil temperature field around through the simulations by fluent and experiments during a long-term.The results give an experimental guidance to the application of GCHPS in Guangdong.
