Résumé

The necessity to substitute high-GWP refrigerants gave a large motivation in the study of new halogenated olefins, characterized by GWP values similar to that of natural refrigerants. Within this group, cis-1-chloro-2,3,3,3-tetrafluoropropene (R1224yd(Z)) is one of the most interesting working fluids for applications in centrifugal chillers or Organic Rankine Cycles (ORC), due to its relatively high NBP (287.15 K). In this paper, 90 experimental compressed liquid density data for R1224yd(Z) will be presented in a wide range of pressures and temperatures. Moreover, 10 saturated liquid density values have been obtained extrapolating the compressed liquid isotherms to the saturated pressure. Liquid densities obtained in this work are compared with calculated values from the equation of state (Akasaka et al., 2017). Totally, the equation well represents the densities, but some data points show larger deviations than the experimental uncertainties. We plan to update the equation based on these densities and other recent measurements.
