摘要
在建立换热器模型时引入过冷度估计和过热度估计,采用分相区集总参数的方法,通过简化分析提取能够反映制冷系统动态特性的最少状态量,建立了制冷系统六阶动态模型。同时采用Matlab的Simulink仿真工具,比较分析六阶模型数据和实验数据,验证六阶模型的正确性。
This paper introduced superheat estimation and subcool estimation into heat exchange model, which used the method of distribution lumped parameter and put forward the six - order dynamic model of refrigeration system by simplified analysis. This model could describe the main dynamic characteristics of refrigeration system with the least state variables. Using Mat- lab and Simulink, compared with experiment results, the validity of the six - order model was confirmed.
