Résumé

The cis-1-chloro-2,3,3,3-tetrafluoropropene (R-1224yd(Z)) is a new low global warming potential promising working fluid in high temperature heat pumps and organic Rankine cycle. In this study, the thermal conductivity was measured in the temperatures from 317 to 416 K with pressures from 1.0 to 4.0 MPa at liquid phase and from 376 to 453 K with pressures from 0.2 to 1.5 MPa at vapor phase. The combined standard uncertainties of thermal conductivity measurements were estimated to be less than ±2.1% at liquid and ±2.3% at vapor phases. On the other hand, the viscosity was measured over the temperature range of 303–424 K at liquid and from 394 to 475 K at vapor phase up to 4.0 MPa. The combined standard uncertainties were estimated to be less than ±2.95% at liquid and ±3.0% at vapor phases. Moreover, correlations were developed at saturation condition.
