Résumé

A combined compression/ejection refrigeration cycle intended for the simultaneous production of cold for refrigeration and freezing, and operating based on environment friendly refrigerants is proposed and analyzed in this study. This makes it possible to valorize the low-temperature heat sources in the ejector cycle, thereby reducing the share of mechanical energy otherwise required to operate the conventional two-stage vapor compression system.
A selection of eight candidates' fluids was performed. The developed simulation model helped to establish the strong dependence between system performances and the ratio of the cooling capacities of refrigeration and freezing. In addition to the effect of the temperature level of cold production, the influence of the ambient temperature on system performance was also analyzed when using refrigerants R290, R152a and R134a.
