摘 要: 基于地埋管换热器的热渗耦合传热模型,对滩涂水岸地质条件下地埋管的换热特性进行分析,从而得到地下水位线、地下水渗流速度以及土壤含水率等参数的影响规律,且利用多元线性回归模型回归得到单位井深换热量、地埋管出口水温与各影响参数的关系式以及各参数的显著性排序,对地埋管换热器的理论分析及工程实践具有指导意义。 A coupled heat conduction and heat advection numerical model for ground heat exchanger (GHE) simulation was used to analyze the heat transfer characteristics of GHE under the special wetland circum- stance. Then we can see the impacts of some factors such as water table, groundwater flow rate and water content etc. Furthermore, through multiple regression analysis for the large quantity simulation results, it is clear to see the relationship and the influence sequence of various factors on heat transfer quantity per meter borehole and water temperature from GHE. Those are beneficial to theoretical research and practice both.
