【摘要】 利用VB编制了简便、快速的地热换热器的设计计算程序。并以单位井深换热量为评价指标对单U型和双U型埋管的换热性能进行分析比较,得出了排热和取热工况下,双U型埋管单位井深换热量均比单U型高。另外,与实际工程的单位井深换热量进行对比,其相对误差很小,符合设计要求。更多还原

【Abstract】 Using VB to compile the easy and fast heat exchanger design calculation procedure.And analysis and comparison between two kinds of heat exchangers were implemented with the evaluation standard of heat exchange.The result shows that the heat exchange quantity of double U shaped is more than that of single U shaped under heating and cooling conditions.Besides, compared with the quantity per well depth of actual project,its relative error is very small and design requirements are reached.更多还原
