AB  - To investigate the performance characteristics of a Double Evaporator Ejector Refrigeration System, a mathematical model based on one-dimensional ejector theory and including the friction effect of the mixing chamber, is established and simulated by the software EES. For refrigeration and freezing temperatures compatible with household refrigeration applications, the resulting code is used to investigate the influence of suction chamber pressure drop ΔP, and the nature of the refrigerant on the performance characteristics of DEERS equipped with a liquid-vapor separator and using environmentally friendly fluids. The simulation results show that the pressure drop, ΔP, has an important influence on the performance of DEERS. For all the fluids tested, apart from the ejector entrainment ratio, U, all the other performance characteristics of the system decrease as ΔP increases. According to these results, it is R717 which leads to the best performance (COPimp =29.2 %, CRred =27.9 %, and VCCimp =38.6 %). The results also show that COPimp decreases when the condensing temperature, TC increases and reaches a minimum. However, VCCimp and CRred are not affected by the change in TC. In addition, COPimp, VCCimp and CRred increase when the refrigeration temperature, Tev1, increases and the freezing temperature, Tev2, decreases.
