摘要：

This study presents the experimental investigation of an ejector-enhanced auto-cascade refrigeration
cycle (EARC) with zeotropic refrigerant R134a/R23. Performance comparisons among the EARC and
two conventional cycles were conducted at selected operating conditions. The effects of ambient temperature,
charged mass fraction ratio of the mixture, throttle valve opening, and heat load on the performance
characteristics of the EARC were investigated. The results indicated that the EARC had more
advantages in terms of lower refrigeration temperature and higher energy utilization efficiency over
the conventional cycles, and the coefficient of performance (COP) and exergy efficiency improvements
of the EARC reached up to 9.6% and 25.1%, respectively. The throttle valve opening was optimal with
respect to the maximum system exergy efficiency determination. The refrigerant R134a/R23 with the
optimal mass fraction ratio of 0.70/0.30 was proposed.
