A　new　combination　system　of　＂three-phase　energy　storage＂　and　solar　absorption　refrigeration　has　been　developed　in　this　paper.　The　operation　process　of　LiBr-H2O　three-phase　energy　storage　system　is　described　in　detail.　Thermodynamic　analysis　models　of　charging/discharging　processes　based　on　the　absorption　principle　are　established　in　order　to　understand　the　dynamic　characteristics　of　three-phase　energy　storage　and　release　processes.　The　dynamic　simulations　of　charging/discharging　processes　are　carried　out　by　using　MATLAB.　The　influences　of　operation　parameters　on　the　characteristic　parameters　of　three-phase　charging/discharging　are　analyzed,　and　the　performance　evaluation　indexes　of　three-phase　energy　storage　system　are　obtained.　The　simulation　results　showed　that　the　lower　initial　concentration　of　LiBr-H2O　solution,　the　smaller　mass　flow　rate　of　LiBr-H2O　sprayed　on　the　heat　exchanger　in　the　energy　storage　tank　and　the　higher　heat　conductance　of　the　heat　exchanger　(KA)　result　in　the　higher　energy　storage　efficiency　and　energy　storage　density.　The　smaller　mass　flow　rates　of　LiBr-H2O　and　the　cooling　water　can　make　the　more　stable　discharging　process　with　longer　cooling　time.　The　research　results　can　provide　theoretical　guidance　for　further　improving　and　optimizing　the　operation　performance　of　three-phase　energy　storage　system　coupling　in　solar　air　conditioning.　(C)　2019　Elsevier　B.V.　All　rights　reserved.
