Summary

A novel combined power and refrigeration cycle is introduced and analyzed from the thermodynamic standpoint. The proposed cycle is an integration of a Kalina cycle equipped with an ejector (EKalina) and an ejector refrigeration cycle (ERC). In order to enhance the overall cycle performance, the possibility of employing two-phase ejectors in combined power and refrigeration cycles is studied. A parametric anal- ysis is conducted to investigate the effects of the key thermodynamic parameters namely turbine inlet pressure, split ratio, basic ammonia concentration, heat source and evaporator temperatures on the cy- cle performance. The developed model is also verified with available data and it is indicated that the mentioned parameters have significant effects on the thermodynamic performance of the system. More- over, results indicate that the proposed cycle exhibits higher exergetic performance compared to former combined power and refrigeration cycles.
