| Abstract: | 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 Matlab and Simulink,compared with experiment results,the validity of the six-order model was confirmed. |
