In　this　paper,　the　Computational　Fluid　Dynamics　(CFD)　technique　is　used　to　investigate　the　influences　of　varying　cooling　loads　on　the　ejector　pressure　recovery　performance　in　an　ejector-based　multi-evaporator　refrigeration　system　(EMERS)　using　R134a　as　the　refrigerant.　The　performance　of　pressure　recovery　in　the　EMERS　reflects　the　performance　of　the　compression　energy　saving.　The　developed　CFD　model　is　first　validated　by　actual　experimental　data　from　the　EMERS.　Turbulence　model　constants　are　carefully　selected　in　order　to　minimize　the　model　prediction　error.　Over　200　different　cases　are　studied　using　the　model　to　find　the　effects　of　varying　cooling　loads　on　pressure　recovery　ratio.　The　results　indicate　that　pressure　recovery　ratio　is　very　sensitive　to　the　varying　primary　and　secondary　flow　cooling　loads.　The　maximum　pressure　recovery　ratio　can　reach　60%　as　the　cooling　loads　vary.　It　was　found　that　in　order　to　keep　the　system　stable,　the　primary　and　secondary　cooling　loads　should　be　maintained　within　+/-　5%　and　+/-　10%,　respectively,　in　which　case　the　pressure　recovery　ratio　will　have　a　maximum　ratio　of　32.8%.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
