Review of Analytical Models for Vertical-borehole Ground Heat Exchangers and Energy Piles
摘要
Abstract
Geothermal heat exchangers,which can utilize shallow geothermal energy,is an innovative energy-saving technology.In this paper,principle of heat transfer underground is firstly introduced,then developments of analytical models of vertical-borehole ground heat exchangers and energy piles are overviewed.Infinite/finite line heat source,cylindrical heat source and spiral heat source models are mainly discussed and compared.The influence of anisotropic heat transfer media (soil) is also summarized.Finally,the feasibility of different models is recommended according to particular circumstances and the current problems and potential development direction are stressed.关键词
