摘　　要：建立了单井回灌地源热泵系统地下换热器传热传质数学模型,通过数值计算对数学模型进行求解。通过与工程实验结果进行比较,表明本文所建数学模型及其数值计算方法,较准确地描述了井壁无渗透的裸管形式及井壁处有循环水渗透的单井回灌地源热泵系统地下换热的传热传质特征,由此得到的计算结果能够满足工程设计精度的要求。A mathematical model of the mass and heat transfer in the Standing Column Well （SCW） system is established and studied by means of numerical solution in this paper. Comparing the numerical solution results with test data shows that the mathematical model and numerical solution method established in this paper can reasonably describe the characters of heat and mass transfer in geothermal heat exchangers of the SCW system no matter there is seepage in the well wall or not.The results of numerical solution can meet requirements for engineering applications.
