摘　　要：以钻孔外有限长线热源模型及钻孔内准三维模型为基础，运用叠加原理，基于VisualStudio开发平台，利用C#语言进行可视化窗体编程，结合重庆地区某地源热泵工程，通过导入DeST能耗模拟软件生成的建筑逐时负荷，对该工程的地埋管换热器进行逐时换热特性模拟，分析土壤热物性，地埋管换热器热短路，系统运行策略三个方面对地源热泵系统性能的影响，计算出不同因素下系统能耗，为地源热泵系统优化设计和运行策略提供依据。Based on the finite line-source model of outside the borehole and a quasi-three-dimensional model of inside the borehole, a visual software were programmed on Visual Studio development platform, using C# language and the superposition principle. Combining a ground-source Heat Pump engineering in Chongqing, heat transfer characteristics of the ground heat exchanger has been simulated, based on the hourly building load, generated by DeST energy consumption simulation software of building. To provide the basises for the optimization design and operation strategy of ground-source heat pump system, soil thermal properties, thermal short circuit and systems operation strategy were presented to analyse the performance, calculate the system energy consumption of ground-source heat pump system.
