In this paper, a transcritical ejector refrigeration cycle using refrigerant R143a, R134a and R717 as working fluids are proposed to improve the performance of the ejector refrigeration systems. The method of solution in this paper was performed by the first and second laws of thermodynamics in theory with EES software. The effect of entrainment ratio and coefficient of performance on some properties of cycle like pressure of generator, evaporator and condenser and temperature of generator, evaporator and condenser have been presented.
