| dc.description.abstract | This work presents an energy analysis of an operating cycle of a conventional refrigerating machine without and with ejector using ternary azeotropic mixtures as refrigerants with the refrigerant R134a, the mixtures considered in this study are: R600a +R1234ze+R13I1, R134a+R1234yf+R600a and R134a+RE170+R600a. A numerical simulation was carried out to evaluate and compare the energy performance of these mixtures with the R134a refrigerant, in particular the determination of the coefficient of performance (COP). The comparison was made for evaporation temperatures (Te) between (-10 and 10) ° C and condensation temperatures (Tc) between (30 and 55) ° C. The results obtained show in particular that the refrigeration system with ejector allows an increase in COP greater than 5.07% compared to that of the conventional refrigeration system and that the performance obtained with the ternary azeotrope mixture R134a+RE170+R600a offers the maximum values of COP compared to the other mixtures (R600a+R1234ze+R13I1 and R134a+R1234yf+R600a) as well as the refrigerant R134a in the two cycles studied. | ar |
