Summary

In the search for substitutes for high global warming potential (GWP) refrigerants, measurements of thermodynamic properties for refrigerants belonging to new halogenated olefins group (HFO) is of strict actuality, due to their GWP, close to that of natural refrigerants, and the lack of information on their properties. One of the most interesting HFOs is cis-1-chloro-2,3,3,3-tetrafluoropropene (R1224yd(Z)), suitable, for its relatively high NBP (287.15 K) and its low vapour pressure, to be used in applications such as Organic Rankine Cycles (ORC), industrial high temperature heat pumps or centrifugal chillers. The paper presents 90 experimental compressed liquid density data for R1224yd(Z) in a range of temperatures and pressures varying from 283.15 K and 363.15 K and from close to saturation pressure up to 35 MPa, respectively. The data were measured by means of a vibrating tube densimeter at isothermal conditions. By extrapolating the isothermal compressed liquid density data at the saturated pressure, 10 saturated liquid density values have also been obtained. A Tait correlation for the compressed liquid density data and a dedicated correlation for the saturated liquid density are presented. Both correlations well represent the experimental data, with a percentage absolute average deviation (AAD%) of 0.1% in both cases. Experimental liquid density data have been compared to literature through the most updated version of the fundamental equation of state proposed by (Akasaka et al., 2017). The equation shows a very good agreement with the present data, considering that most of the data are in the extrapolation areas of the equation.
