Thermal Conductivity Measurements for trans-1,3,3,3-Tetrafluoropropene (R1234ze(E)) in Liquid Phase
, 2022 Refrigeration, heat pumps and air conditioning sectors are under pressure to find low GWP working fluids suitable for the substitution of the current high GWP refrigerants, as required by the European Regulation EU No 517/2014. Halogenated olefins (HFOs and HCFOs) are the most promising group of synthetic compounds being considered for such purpose ...

Surface tension of low GWP refrigerants R1243zf, R1234ze(Z), and R1233zd(E)
International Journal of Refrigeration, 2015 Abstract The surface tension of R1243zf, R1234ze(Z), and R1233zd(E) were measured at temperatures from 270 K to 360 K by an experimental apparatus based on the differential capillary rise method. The deviation between the measured surface tension of R134a and R245fa and the calculated surface tension with REFPROP 9.1 ( Lemmon et al., 2013 ) was ±0.13
