摘要
通过采用移动边界的建模方法建立了蒸发器动态仿真数值模型,并推导出冷凝器的移动边界法数学公式,在完成其它主要部件数值仿真模型的基础上,建立了氟利昂制冷循环系统完整的热力学仿真模型;提出了适应于该移动边界法模型的系统动态仿真算法;在MAT-LAB/SIMULINK仿真平台下完成了系统动态仿真程序的设计;对系统进行了仿真研究,得出系统在一定外界环境下的动态运行特性.
A new moving boundary （MB） method is presented for establishing the dynamic model of evaporator in this paper, and using this method, the dynamic model of condenser is given ; with the model of expansion valve and compressor, the model of refrigeration cycle is established finally ; a simulation algorithm is proposed for the system MB model; the simulations using this model has been conducted base on the MATLAB/SIMU- LINK and the dynamic performances has been studied.
