Review and improvement on heat transfer model of ground heat exchangers.

[In Chinese. / En chinois.]

Author(s) : FAN R., MA Z.

Type of article: Article

Summary

The authors review the existing calculation theories, numerical heat transfer models and their calculation methods for the design of ground heat exchanger (GHE), and find that almost all the models are only based on the heat conduction theory without considering the influence of groundwater advection. Indeed, this work illustrates that the groundwater advection has a major influence on the heat transfer of GHE and so establishes the heat transfer model of GHE covering both heat conduction and groundwater advection. Through calculation for single well pipe GHE, it finds that groundwater advection enhances the heat transfer.
