摘要：

A dynamic simulation of a large scale existing refrigerator has been performed using the software Aspen Hysys(R). The model comprises the typical equipments of a cryogenic system: heat exchangers, expanders, helium phase separators and cold compressors. It represents the 400 W @ 1.8 K Test Facility located at CEA - Grenoble. This paper describes the model development and shows the possibilities and limitations of the dynamic module of Aspen Hysys(R). Then, comparison between simulation results and experimental data are presented; the simulation of cooldown process was also performed.
