ABSTRACT

Measurements of PvT properties, saturated densities and critical parameters were carried out for a lowGWP refrigerant: 3,3,3-trifluoropropene (HFO1243zf, CF3CH=CH2). Seventy-five PvT property data along 7 isochores around the critical point were obtained in the temperature range from 328 K to 430 K, in the density range between 50 kg*m-3 and 899 kg*m-3, and at pressures up to 6.9 MPa by the isochoric method. Fourteen saturated densities were obtained by the observation of meniscus disappearance in the critical region. On the basis of these measurements, the critical parameters of Tc = 376.93 K and c = 414 kg*m-3 were determined. The experimental data obtained are compared with an available equation of state
