为了进一步降低传统压缩-喷射制冷循环（CERC）的耗电量，首次提出了一种新型的带经济器的压缩-喷射制冷循环（CERCE）。一个模型的开发和验证，以研究周期。基于COP和COPg对CERCE循环进行了分析，并与传统的压缩-喷射循环（CERC）进行了比较。在所研究的温度范围内，CERCE的COP和COPg始终高于CERC。CERCE的最大COP和COPg（6.30，2.40）分别比CERC的最大COP和COPg（5.17，2.27）高21.95%和5.48%，这表明CERCE具有良好的节能潜力，证明CERCE可以改善能源性能。分析表明，这种改善主要是由压气机质量流量的降低引起的，而二次流量的降低和雾沫夹带比的增加也有积极但非常轻微的影响。在COP的基础上，得到了两种循环的最佳操作参数：Tg = 75 °C，Tm = 7 °C。以COPg为基础，优化的操作参数为Tg = 55 °C，Tm = 26 °C。这些结果为实验研究和实际操作提供了指导。
In this paper, a novel compression-enhanced ejector refrigeration cycle with an economizer (CERCE) is proposed for the first time to further reduce the electric consumption of conventional compression-ejection refrigeration cycle (CERC). A model is developed and validated to study the cycle. The proposed cycle (CERCE) is analyzed and compared with conventional compression-ejection cycle (CERC) based on COP and global COP (COPg). In the studied temperature ranges, the COP and COPgof CERCE are always higher than those of CERC. The maximum COP and COPgfor CERCE (6.30, 2.40) are 21.95% and 5.48% higher than those of CERC (5.17, 2.27) respectively, which demonstrates the excellent energy-saving potential of CERCE and proves that CERCE can improve energy performance. Analysis shows that the improvement is mainly caused by the decrease in compressor mass flow rate, while the decrease in secondary flow rate and the increase in entrainment ratio also have positive but very slight effects. Based on COP, optimized operating parameters for both cycles are obtained asTg= 75 °C andTm= 7 °C. Based on COPg, the optimized operating parameters areTg= 55 °C andTm= 26 °C. These results provide direction for experimental study and practical operation.
