Energy and Exergy Efficiency Analysis of an Ejector‐Expansion Refrigeration Cycle Using the Working Fluid R134a and Its Potential Substitutes

open access: yesEnergy Science &Engineering, Volume 13, Issue 5, Page 2389-2400, May 2025.
ABSTRACT This paper proposes an ejector‐expansion refrigeration cycle (EERC) with two evaporating temperatures to recover partial expansion work and greatly reduces the throttling loss of the other expansion valve connected to the evaporator compared with the conventional bievaporator refrigeration cycle (CBEC).
