Pressure–volume–temperature–composition (PVTx) properties of the binary refrigerant difluoromethane (HFC-32) + 1,1,1,2-tetrafluoroethane (HFC-134a) have been measured by means of a constant-volume apparatus coupled with an expansion procedure. Two hundred sixty PVTx values were measured in a range of temperatures from 320 to 440 K, pressures from 1.5 to 6.2 MPa, and densities from 61 to 183 kg.m−3.
