Analysis reveals the impact of operational parameters on coefficient of performance and entrainment ratio of ejector cooling systems, indicating R134a and R152a as top performers.
Key Points
Results indicate that secondary flow superheating improves coefficient of performance while minimally affecting entrainment ratio.
Among the refrigerants analyzed, R134a and R152a exhibited the highest coefficient of performance in ejector cooling systems.
Ejector cooling system performance is significantly affected by generator temperature and primary nozzle superheat, emphasizing their importance.
The model developed serves as a reliable tool for designing and optimizing ejector cooling systems with various working fluids.
