چکیده    In this study,theoretical investigations of double evaporator refrigeration system and with adding an ejector to the current system were carried out using energy and momentum equations. the relative increase in cop with respect to the conventional double evaporator refrigeration system was analyzed in terms of condenser and evaporator temperatures. also exergy analyses of systems were examined and results were showed graphically. in the study,r134a and its potential substitute r1234yf were used. the analyses showed that cop improvements of the proposed system by using ejector as an expansion device were approximately 15% for r134a and about 17% for r1234yf,respectively.
