Abstract The performance of an ejector-assisted condenser outlet split dual-evaporator cycle is compared with a conventional albeit consisting pressure reducing valve. cycles do not employ any separator due to its inability efficiently separate the liquid and vapor phases. comparison both has been made for same cooling capacity in low-temperature evaporator unit flow rate R134a R1234yf as refrigerants. impacts changing operating temperatures have examined current investigation. study reveals that increase temperature high-temperature evaporator, yields, while plummets cycles. Further, compressor work allayed cycle; thus, COP enhanced considerably. percentage improvement over basic obtained from 14.7 17.53% refrigerant 14.45 17.32% R134a; however, R12134yf slightly lower than R134a. ejector modeled assuming constant theory. observed trend indicates entrainment ratio improved rise whereas it decreased evaporator.
