Accurate thermo-physical data are of utmost interest for the development of new efficient refrigeration systems. Carbon dioxide (R744) and 1,1-difluoroethane (R152a) are addressed here. Isothermal (vapor + liquid) equilibrium data are reported herein for (R744 + R152a) binary system in the (258 343) K temperature range and in the (0.14 to 7.65) MPa pressure range. A reliable static-analytic method taking advantage of two online ROLSITM micro capillary samplers is used for all thermodynamic measurements. The data are correlated using our in-house ThermoSoft thermodynamic model using the Peng Robinson equation of state, the Mathias Copeman alpha function, the Wong Sandler mixing rules, and the NRTL model.
