Résumé

In this study, a modified subcooling vapor-compression refrigeration cycle (MSVRC) using refrigerant mixture R290/R600a was proposed for applications in refrigerator-freezers. In the MSVRC, a phase separator is utilized to split the refrigerant mixture and obtain refrigerants at two different mass fractions after partial condensation in the condenser. Moreover, an internal heat exchanger is introduced to enhance the overall system performance. Energetic and exergetic analysis methods were used to theoretically evaluate the system operating performance of MSVRC and compared with the conventional vapor-compression refrigeration cycle (CVRC). The simulation results show that the MSVRC outperforms CVRC in terms of coefficient of performance (COP) and exergy efficiency. Under the given operating condition, the COP and exergy efficiency of the MSVRC can be improved up to 5.27% and 11.4%, respectively, as compared to those of CVRC. The system performance characteristics of the proposed cycle demonstrate its potential advantages for application in domestic refrigerator-freezers.
