摘要
介绍了土壤源热泵竖直埋管换热器钻孔外的传统的无限长线热源模型,无限长圆柱模型,有限长线热源模型以及改进后的热湿传递的线热源模型,变热流的线热源模型,土壤分层的线热源模型。分析了各种模型之间的联系、区别以及优缺点。提出了完善土壤源热泵竖直埋管换热器钻孔外传热模型需进一步研究的内容。
This paper introduces some heat transfer model of vertical pipe ground source heat pump heat exchanger thermal model such as traditional infinite long-term heat source model, infinitely long cylinder model, the limited long-term heat source model, as well as improved heat and moisture transfer line heat source model, variable heat flux lines heat source model, the soil layer line heat source model, and analyzes the linkages among the various model.s, the difference as well as the advantages and disadvan- tages. Proposes the further research work on improving vertical pipe grouhd source heat pump heat exchanger thermal model.
