Résumé

This paper describes a test rig of an auto-cascade refrigeration system, which can obtain a temperature of -80°C and offer a refrigerating output of 100 W. This cycle, which employs a proper mixture refrigerant, can realize a cooling cascade automatically. After a great lot of experiments, it is shown that this system can achieve designed temperature and refrigerating output. At the mean time, the system runs credibility with well oil circle. R-14/R-22 was used as the working pair in this study and refrigerant charge and composition of binary refrigerant are researched.
