| 摘 要： | 以钻孔壁为界,将所研究的传热区域划分为土壤部分和钻孔内两部分.对于钻孔外土壤部分的传热过程,采用线热源理论建立非稳态模型进行分析讨论;在钻孔内,对一维模型和二维模型进行了对比,从而得出增强地下换热器换热的措施.

| Abstract: | Underground heat exchanger is an important component of soil-source heat pump system.The heat transfer in underground heat exchanger is unsteady-state process.Taking borehole wall as a division interface,this paper divides the heat transfer zone of vertical underground heat exchanger was divide into two parts:soil zone and borehole zone.An unsteady heat transfer model was established using line heat source theory to analyze and discuss the heat transfer process in soil zone.For borehole zone,one-dimensional... |
