In　this　study,　a　novel　dual-nozzle　ejector　enhanced　refrigeration　cycle　is　presented　for　dual　evaporator　household　refrigerator-freezers.　The　proposed　ejector　equipped　with　two　nozzles　can　efficiently　recover　the　expansion　work　from　cycle　throttling　processes　and　enhance　cycle　performances.　The　performances　of　the　novel　cycle　are　evaluated　by　using　the　developed　mathematical　model,　and　then　compared　with　that　of　the　conventional　ejector　enhanced　refrigeration　cycle　and　basic　vapor-compression　refrigeration　cycle.　The　simulation　results　show　that　for　the　given　operating　conditions,　the　coefficient　of　performance　(COP)　of　the　novel　cycle　using　refrigerant　R134a　is　improved　by　22.9-50.8%　compared　with　that　of　the　basic　vapor-compression　refrigeration　cycle,　and　the　COP　improvement　is　10.5-30.8%　larger　than　that　of　the　conventional　ejector　enhanced　refrigeration　cycle.　The　further　simulation　results　of　the　novel　cycle　using　refrigerant　R600a　indicate　that　the　cycle　COP　and　volumetric　refrigeration　capacity　could　be　significantly　improved.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
