摘　　要：土壤源热泵研究的核心问题之一就是对于地埋管换热器的传热模型的研究。模型的建立和选择对土壤源热泵和埋管的设计影响重大。本文回顾了国内外不同的地埋管换热器的传热模型及其改进与发展,重点叙述了解析模型的改进,发现目前研究中欠缺对于管群间传热影响的研究,如不同埋管形式、埋管间距之间的热干扰及热堆积等的研究。同时关于土壤特性对于传热的影响的研究不够深入。本文还指出了对于地埋管传热模型的下一步研究重点。One of the core problems of the ground source heat pump research is the study on the heat transfer model of borehole heat exchangers. The establishment and choice of the model has a great influence on the design of the heat pump and buried pipes. This paper reviews the studies and development on the heat transfer model in China and around the world. The paper mainly describes the analytical model, found that the current lack of research on the effects of heat transfer between the pipe group, such as the thermal interference and heat accumulation of different arrangement and spacing of the buried pipes. And the effects of soil characteristics on heat transfer should be investigated in further research. The paper also points out the future research priorities for the heat transfer model of borehole heat exchangers.
