The　trigeneration　combined　the　electricity,　cooling　and　heating　makes　adiabatic　compressed　air　energy　storage　system　(ACAES)　popular　as　an　energy　storage　technology.　Based　on　thermodynamic　analysis,　this　paper　studies　the　influence　on　the　system　performance　of　four　variable　factors,　including　compression　stages,　expansion　stages,　water　(heat　storage　medium)　mass　flow　rates　in　charging　process　and　discharging　process　to　provide　a　guidance　for　the　design　of　ACAES　for　different　user　demand.　The　results　show　that　changing　these　four　factors　can　achieve　different　energy　output　distributions　in　a　very　wide　range　(power　supply　ratio　is　0.50–0.86,　heating　output　ratio　is　0.00–0.39,　cooling　supply　ratio　is　0.00–0.41).　Simulation　results　also　indicate　that　fewer　compression　and　expansion　stages　are　suggested　for　the　cases　requiring　shorter　running　time.　Furthermore,　according　to　this　study,　less　compression　stages　than　expansion　is　good　for　electricity　generation　and　more　compression　stages　is　good　for　cooling　supply.　And　for　large　heating　supply　demand,　less　compression　is　suggest.　Besides,　the　energy　efficiencies　for　different　configurations　of　trigenerative　ACAES　are　also　achieved　which　are　changed　from　0.62　to　0.87　and　the　best　configurations　with　highest　system　efficiency　are　also　presented.　Finally,　by　economic　analysis,　the　most　economic　condition　is　achieved.　©　2021　Elsevier　Ltd
