This　paper　proposes　an　ejector　enhanced　vapor　compression　refrigeration　cycle　(EVRC)　using　zeotropic　hydrocarbon　mixture　R290/R600a　for　applications　in　domestic　refrigerator/freezers.　An　internal　heat　exchanger　and　a　phase　separator　are　utilized　in　EVRC　to　improve　the　system　performance.　An　ejector　is　adopted　to　further　enhance　the　cycle　performance.　The　energy　and　exergy　analysis　of　EVRC　are　performed　to　evaluate　the　system　operating　characteristics　and　compared　with　the　Lorenz-Meutzer　vapor　compression　refrigeration　cycle　(LVRC)　and　the　traditional　vapor　compression　refrigeration　cycle　(TVRC).　The　results　indicate　that　EVRC　can　provide　the　uppermost　advantages　over　both　TVRC　and　LVRC　under　the　operating　conditions.　Compared　with　TVRC,　the　EVRC　can　significantly　improve　the　coefficient　of　performance,　volumetric　refrigeration　capacity　and　exergy　efficiency　by　13.5%,　19.3%,　and　13.4%,　respectively.　The　performance　characteristics　of　the　proposed　cycle　demonstrate　its　potential　advantages　for　application　in　domestic　refrigerator/freezers.
