摘要
本文应用移动边界法(MB)对冷凝器建立了动态仿真数学模型,模型体现了冷凝器内各个相区长度随时间的变化,模型最终可以化为常微分线性方程组的形式,在求解上更为方便且兼顾了仿真的效率和精度,模型可提供冷凝器详细的性能参数;研究了在系统不同的控制参数阶跃情况下冷凝器的动态响应,获得了冷凝器的动态特性,冷凝器的动态特性是冷凝器动态优化设计和编制系统控制规律的基础。本文中的冷凝器建模方法适合于系统级仿真研究。
In this paper, a new moving boundary [2] (MB) method was employed to develop the dynamic simulation mathematical model of condenser. The simulation model reflects the variation of length of different phase region of condenser during working. Finally, the model could be simplified to a set of ordinary derivative equation, it could be solved more easily. The simulation model is numerical fast and accurate and very robust to the sudden change of control parameters in the vapor cycle system. This paper studied the dynamic response of condenser in the step change of different control parameters. Dynamic performance is the base of optimum design of condenser and system control rules.
