PURPOSE: A refrigeration system for refrigerator having two evaporators is provided to achieve a maximized energy efficiency with a minimum cost by mixing the refrigerant passed through the freezing compartment evaporator and the refrigerating compartment evaporator, respectively, so as to increase the pressure of the refrigerant and supplying the mixture to the compressor. CONSTITUTION: A refrigeration system comprises a compressor(51) for compressing refrigerant; a condenser(53) for condensing the refrigerant compressed in the compressor; a freezing compartment expansion unit(56) for reducing, into a first pressure level, the pressure of the refrigerant condensed by the condenser; a refrigerating compartment expansion unit(58) for reducing, into a second pressure level, the pressure of the refrigerant condensed by the condenser; a freezing compartment evaporator(61) for evaporating the refrigerant expanded by the freezing compartment expansion unit and cooling the ambient air to be supplied to the freezing compartment into a first temperature level; a refrigerating compartment evaporator(63) for evaporating the refrigerant expanded by the refrigerating compartment expansion unit and cooling the ambient air to be supplied to the refrigerating compartment into a second temperature level; and an ejector(65) for mixing the refrigerant passed through the freezing compartment evaporator and the refrigerating compartment evaporator, respectively, and supplying the mixture to the compressor.
