Abstract

Highlights: Compressed liquid density of low GWP refrigerants. Measurements carried out using a vibrating tube densimeter. Density measurements of cis -1, 3, 3, 3-tetrafluoroprop-1-ene R1234ze(Z) up to 30 MPa. Density measurements of trans -1-Chloro-3, 3, 3-trifluoropropene R1233zd(E) up to 25 MPa. Comparison with other literature data and dedicated equation of state. Abstract: In this work, liquid phase densities of two fourth generation refrigerants, cis -1, 3, 3, 3-tetrafluoroprop-1-ene R1234ze(Z) and trans -1-chloro-3, 3, 3-trifluoropropene R1233zd(E), are measured. The densities have been measured using a vibrating tube densimeter over the temperature range from 273.15 K to 333.15 K for pressures up to 30 MPa. For both fluids, the expanded uncertainty at a confidence level of 95% in the density measurements is estimated to be 0.07% over the entire T – p range measured.
