Experimentally Performance Evaluation of a Dual Evaporator Ejector Refrigeration System with Diffuser Outlet Split Configuration under Varied Compressor Inlet Pressures

In this research, an experimental investigation was conducted on a dual-evaporator ejector system (DEES). The experiments were conducted under two distinct configurations, known as condenser outlet split (COS) and diffuser outlet split (DOS), across varying compressor inlet pres-sures. The system wa...

Description
Summary:In this research, an experimental investigation was conducted on a dual-evaporator ejector system (DEES). The experiments were conducted under two distinct configurations, known as condenser outlet split (COS) and diffuser outlet split (DOS), across varying compressor inlet pres-sures. The system was initially operated in accordance with the COS configuration followed by operation under the DOS configuration. The comparison revealed a 9% reduction in the compressor work within the DOS configuration relative to the COS configuration. Evaporator#2 cooling capacity was 14% higher in the DOS compared to the COS. Moreover, the total cooling capacity achieved in the COS mode exhibited a 16% increase in comparison to the DOS mode. Furthermore, research findings indicate that by operating the DEES in the DOS configuration, full refrigerant separation can be achieved, leading to enhanced operational efficiency.
