摘要:
采用FLUENT模拟软件,建立起U型地埋管换热器三维传热模型.分别模拟了有、无添加隔热板时的工况,对热短路进行数值模拟,分析了对地埋管换热器性能的影响.通过对比两种工况下的温度云图和出口温度监测图,证明了两支管间热短路现象严重,而且添加隔热板后,进出口温差变大可达3.94 ℃,可使单位井深换热量提升6.13%.
Abstract:
The paper simulates with FLUENT software to build three -dimensional heat transfer model of U-tube buried tube heat exchanger. When adding insulation panels are simulated with and without conditions,to simulate the thermal circuit,the influence of the performance of ground heat exchanger is analyzed. By comparing the two kinds of working conditions of temperature and outlet temperature monitoring diagram,simulation proves that the hot short circuit phenomenon is serious between the two branch pipe,and after adding insulation board,the import and export temperature difference can reach 3.94 ℃,and the unit well depth in heat can be made to improve 6.13%.
