摘要：
This paper reviews the heat transfer model and calculation methods on the ground-coupled heat pump (GCHP), and found that almost all the model did not consider the influence of groundwater seepage, although groundwater seepage on the pipe heat exchanger has a big influence. Based on the theory of groundwater seepage and heat transfer theory, a new mathematical model coupled with groundwater flow and heat transferring between heat exchanger and ground soil mass are established, which conceded of the heat conduction and the role of the common groundwater seepage of infiltration coupled heat transfer model, which can provides a theoretical support for the calculation and analysis of ground-coupled heat pump heat exchanger.
