| 摘 要： | 介绍了地源热泵单U垂直埋管的几种地下换热器传热模型,重点介绍和分析了改进的圆柱热源理论模型和"负荷聚合"思想以及可用于短时间范围传热模拟的数值解的理论模型.采用"负荷聚合"的圆柱热源理论模型大大缩短了全年传热模拟的时间;而适用于短时间尺度的数值解模型对地下换热器和地源热泵系统的设计以及能量分析具有现实意义.

| Abstract: | Several transfer models of single vertical U-tube ground heat exchanger about geothermal heat pump(GHP) developed in the overseas and our country are discussed.The ameliorative cylindrical heat source solution using the methodology of Incorporate Load Aggregation and the numerical model which can predict the short term fluctuations are recommended and analysed.The simulation time of annual heat pump energy adoptted Incorporate Load Aggregation is heavy reduced.The short-term numerical model is a very practical function for design of ground loop heat exchangers and ground source systems and for energy analysis of GHP. |
