【摘要】 本文通过分析地源热泵系统的组成,分别建立了地源热泵系统的三个组成环路的数学模型：地下埋管换热器环路模型、热泵机组环路模型、末端水环路模型。通过质量守恒、能量守恒和动量守恒关系,利用 MATLAB-SIMULINK 模块,搭建整个系统的动态仿真模型。另外在仿真系统建立后,采用具有编程简单、数据输入方便、界面交互性强等优点的 GUI 来完成可视化界面的设计。充分利用 SIMULINK 和 GUI 各自强大的功能,将二者结合起来实现地源热泵系统的动态仿真。更多还原

【Abstract】 With the analysis of the ground source heat pump components,mathematical model of the ground source heat pump system is established,composed of the underground heat exchanger loop,heat pump units loop and the end of the water loop.Adoption of conservation equation of mass,energy and momentum conservation equation,it structures the system dynamic simulation model with MATLAB-SIMULINK module and GUI visualization interface design.The advantages of the GUI programming is simple,convenient in data entering and good surface interaction.With the advantage of the powerful GUI,it is convenient to achieve the dynamic simulation of the ground source heat pump system.更多还原
