This paper describes performance comparison of two types of hybrid configuration of power generation and refrigeration cycles using ammonia-water mixture by simulation calculation. Difference between two configurations is the ammonia mass fraction of solution from the turbine system (power generation cycle) to the ammonia absorption refrigerator (refrigeration cycle). The newer configuration (configuration 2) supplies higher mass fraction solution to the refrigerator. As a result, both configurations show larger system net power than separate operations when the basic composition (the ammonia mass fraction of the evaporator in the turbine system) is 0.45 kg/kg. The performance gains of configuration 1 and 2 are 13.6% and 13.8%, respectively.
