In　this　paper,　an　independent-developed　solar　parabolic　trough　collector　(PTC)　for　solar　air　conditioning　has　been　adopted　in　a　solar　air　conditioning　system　with　a　three-phase　accumulator.　The　composition　and　operation　strategy　of　the　system　are　elaborated　in　detail.　In　view　of　the　measured　data　of　the　solar　energy　and　the　cooling　load　demand　of　buildings,　the　reasonable　matching　design　of　the　solar　collector,　absorption　refrigeration　chiller　and　three-phase　accumulator　is　carried　out.　On　this　basis,　the　dynamic　performance　of　the　solar　air　conditioning　system　with　the　independent-developed　PTC　is　analyzed.　The　calculation　and　analysis　results　show　that　the　solar　air　conditioning　system　with　a　three-phase　accumulator　can　continuously　and　steadily　supply　cooling　for　buildings　day　and　night.　Cooperative　operation　of　the　solar　absorption　refrigeration　with　the　PTC　and　the　three-phase　accumulator　can　not　only　improve　the　efficiency　of　the　parabolic　trough　collector,　but　also　ensure　the　high　energy　storage　efficiency　of　the　three-phase　accumulator.　The　average　parabolic　though　collector　efficiency　is　67.5%,　the　energy　storage　efficiency　of　the　three-phase　accumulator　is　0.8,　the　solar　fraction　can　reach　82.4%.　Based　on　the　economic　analysis,　the　investment　of　the　solar　air　conditioning　system　with　a　three-phase　accumulator　is　acceptable.　(C)　2020　Elsevier　Ltd.　All　rights　reserved.
