N2 - The experimental pressure-volume-temperature-composition (PVTx) properties of the binary refrigerant 1,1-difluoroethane (HFC-152a) + 1,1,2,2-tetrafluoroethane (HFC-134) have been measured by means of a constant-volume method coupled with expansion procedures in an extensive range of temperatures, pressures, and densities. A total of 202 PVTx property data were measured in a range of temperatures from 320 to 440 K, pressures from 1.0 to 4.3 MPa, and densities from 54 to 155 kg/m3. A Clausius-Clapeyron-type correlation for the dew-point pressures was developed which can reproduce the measurements within ±5 kPa.
