To　overcome　the　weaknesses　of　traditional　working　pairs　(H2O/LiBr　and　NH3/H2O)　in　the　absorption-refrigeration　systems,　2,3,3,3-tetrafluoroprop-1-ene　(R1234yf)/ionic　liquid　(IL)　as　a　promising　working　pair　has　attracted　wide　attention.　Using　an　isochoric　saturation　method,　the　solubilities　were　measured　for　three　working　pairs　(R1234yf/[emim][Ac],　R1234yf/[bmim][Ac]　and　R1234yf/[P66614][Cl])　from　283.15　to　343.15　K　and　the　data　was　correlated　by　the　NRTL　model.　Solubilities　rise　with　a　decrease　in　temperature　and　an　increase　in　pressure.　Highest　solubility　is　in　[P66614][Cl],　followed　by　[bmim][[Ac]　and　[emim][Ac].　The　cooling　performance　was　studied　for　the　single-effect　and　compression-assisted　system　using　several　R1234yf/IL　mixtures.　The　effects　of　compression　ratio,　generation　and　evaporation　temperature　on　the　coefficient　performance　(COP)　and　circulation　ratio　were　analyzed.　Under　the　condensation　temperature　of　303　K,　generation　temperature　of　363　K　and　absorption　temperature　of　303　K,　the　maximum　COPs　for　[emim][Ac],　[bmim][Ac]　and　[P66614][Cl]　are　respectively　013,　0.23,　and　0.46　in　the　compression-assisted　system.　[P66614][Cl]　has　the　highest　COP　and　exergy　coefficient　of　performance　(ECOP)　while　[emim][Ac]　shows　lowest　under　the　same　condition.　©　2020　Elsevier　Ltd
