| 摘 要： | 回顾了国内外关于地埋管换热器的设计计算理论、传热模型及其计算方法,发现几乎所有的模型都未考虑地下水渗流的影响。举例说明地下水流动对地埋管换热器有较大的影响,建立了考虑热传导和地下水流动共同作用的地埋管换热器的传热模型,并且对单井地埋管进行了初步分析,结果表明地下水渗流能增强盘管的换热能力。

| Abstract: | Reviews the existing calculation theories, numerical heat transfer models and their calculation methods for the design of ground heat exchanger (GHE), and finds that almost all the models are only based on the heat conduction theory without considering the influence of groundwater advection. Illustrates that the groundwater advection has a major influence on the heat transfer of GHE. Establishes the heat transfer model of GHE covering both heat conduction and groundwater advection. Through calculation for single well pipe GHE, finds that groundwater advection enhances the heat transfer. |
