Measurements of the bubble-point pressures and the saturated-liquid densities of the binary mixtures difluoromethane + 1,1,1,2-tetrafluoroethane (R-32 + R-134a) and pentafluoroethane + 1,1,1,2-tetrafluoroethane (R-125 + R-134a) and the ternary mixture difluoromethane + pentafluoroethane + 1,1,1,2-tetrafluoroethane (R-32 + R-125 + R-134a) are presented. The estimated uncertainties of ±15 mK in temperature, ±12 kPa in pressure, ±0.2% in density, and ±0.3 mol % in composition are reported. The Peng-Robinson equation and the modified Hankinson-Brobst-Thomson equation have been optimized to represent the measured properties satisfactorily. The calculated temperature glides of the mixtures of the present interest have also been presented.
