Abstract
In this study, the first and second law analysis of vapor compression refrigeration cycle with two-stage and economiser were carried out. R134a was used in system as refrigerant. The necessary thermodynamic values for analyses were calculated by Solkane program. The coefficient of performance (COP), exergetic efficiency (ηex) and total irreversibility rate of the system in the different operating conditions were investigated for this refrigerant. As a result, the highest coefficient of performance value and exergy efficiency value was obtained in the condenser temperature 25 oC and evaporator temperature 5 oC in the refrigeration system with two-stage and economiser. The highest irreversibility value was obtained in the condenser temperature 45 oC and evaporator temperature -15 oC in the refrigeration system
