Abstract

In this study, a thermodynamic study based on heat transfer characteristics of the ammonia /water solar combined ejector-absorption refrigeration systemis performed. The influences of the generator temperature,heat recovery ratio, solution circulation ratio, areinvestigated in order to gauge the least amount of heat transfer area that is needed for a given heat duty and the coefficient of performance (COP). The results showed that the increases in the heat recovery ratio of the solution heat exchanger improved the coefficient of performance. It is also found that the lower solution circulation ratio is better for both the coefficient of performance (COP) and the heat transfer area.It is evident that the COP improves with increases heat transfer area of the system at fixed operation condition. The total heat transfer area required is7.764 m2at generator temperature is 100°C to reach the COP nearly 0.6148 for system cooling capacity of 5 kW.
