新型低 GWP 制冷剂的 PvT 特性、蒸气压和饱和密度；测量R1224yd(Z)（顺式1-氯-2,3,3,3-四氟丙烯；CF3CF=CHCl）。沿着过热区域的四个较低密度等容线获得了 46 个 PvT 特性数据； 22、48、55和103 kg·m–3，以及压缩液体区域中的三个更高密度等容线； 970、1107 和 1197 kg·m–3，压力高达 6.4 MPa。在 310 至 410 K 的温度范围和高达 2393 kPa 的压力下获得了 15 个蒸气压数据，并根据这些蒸气压测量结果制定了蒸气压相关性。饱和蒸汽和液体密度通过目视观察关键区域中汽液弯月面的消失直接测量，并且还通过蒸汽压曲线与PvT性能等容线的交点以图形方式确定。此外，还确定了R1224yd(Z)的临界温度Tc= 428.69 ± 0.02 K，临界密度ρc= 535 ± 5 kg·m–3，临界压力Pc= 3331 ± 3 kPa。
PvTproperties, 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-sixPvTproperty 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–3at 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 thePvTproperties. In addition, the critical temperatureTc= 428.69 ± 0.02 K, the critical density ρc= 535 ± 5 kg·m–3, and the critical pressurePc= 3331 ± 3 kPa for R1224yd(Z) were determined.
