This study focuses on optimizing the Absorption Refrigeration Cycle (ARC) to enhance performance and minimize energy consumption. A novel system, the Diffuser Absorption Refrigeration Cycle (D-ARC), has been developed to achieve this objective. In this system, a diffuser is positioned between the evaporator and absorber, resulting in higher pressure in the absorber compared to the evaporator. This increased absorber pressure reduces the circulation ratio and boosts efficiency. The study determines the coefficient of performance (COP), exergetic coefficient of performance (ECOP), and circulation ratio (f) for the D-ARC system at various generator temperatures. These calculations consider both traditional working pairs (NH3/H2O) and different ionic liquid working pairs, including NH3/[EMIM][BF4], NH3/[DMIM][DMP], and NH3/[EMIM][ETSO4]. A comparative analysis of D-ARC, E-ARC, and ARC reveals that the D-ARC system achieves superior COP and ECOP values. The highest COP and ECOP values are observed with the working pair NH3/[EMIM][BF4] (COP: 0.85, ECOP: 0.35), whereas the lowest values are found with the NH3/H2O pair (COP: 0.63, ECOP: 0.26).
