摘要：

According　to　the　mass　conservation　and　energy　conservation　theorem,　established　a　finite　length　cylindrical　surface　heat　and　moisture　transfer　model　which　base　on　the　cylindrical　heat　transfer　model　of　vertical　ground　source　heat　exchanger　for　soil　layer　around　geothermal　borehole.　Using　COMSOL　multi-physics　coupling　analysis　software,　simulated　the　non-steady-state　heat　and　moisture　transfer　for　soil　layers　of　heat　exchanger　under　summer　operating　conditions,　and　analyzed　the　influence　in　temperature　field　and　moisture　field　of　soil　layers　exerted　by　the　heat　and　moisture　transfer　under　different　soil　thermal　properties　and　initial　moisture　contents.　At　last　there　is　verification　by　FLUENT　software.　©　2014　IEEE.
