Abstract
This paper describes performance comparison of separate and hybrid systems of power and cooling cycle that is combined with Kalina cycle and ammonia absorption refrigeration cycle. Authors emphasis on utilization of T-S diagram in order to visualize the factors of the improvement in net output power by comparing with idealized cycle such as Maximum Power cycle and Minimum input compression work for refrigeration cycle. Results of case study show that exergy efficiency of the hybrid system combining with Kalina and ammonia absorption cycle is 16.9% higher than that of the separate operation of each cycle. However, the total thermal conductance of the hybrid system is 5.32% larger than that of separate one.
