Abstract
PvT properties, vapor pressures, and saturated densities for a new low-GWP refrigerant; R1224yd(Z) (cis-1-chloro-2,3,3,3-tetrafluoropropene; CF3CF=CHCl), were measured. Forty-six PvT property data were obtained along four lower density isochores in the superheated region; 22, 48, 55, and 103 kg·m-3, and three higher density isochores in the compressed liquid region; 970, 1107, and 1197 kg·m-3 at pressures up to 6.4 MPa. Fifteen vapor pressure data were obtained in the temperature range from 310 to 410 K and at pressures up to 2393 kPa, and a vapor pressure correlation was formulated based on these vapor pressure measurements. Saturated vapor and liquid densities were directly measured by the visual observation of the vapor-liquid meniscus disappearance in the critical region, and also graphically determined by the intersections of the vapor pressure curve and the isochores of the PvT properties. In addition, the critical temperature Tc = 428.69 ± 0.02 K, the critical density ρc = 535 ± 5 kg·m-3, and the critical pressure Pc = 3331 ± 3 kPa for R1224yd(Z) were determined.
