R1234ze(Z) (cis-1,3,3,3-Tetrafluoropropene), with the 10 d atmospheric life time and <1 global warming potential (GWP) value, has been investigated in refrigeration, heat pump, organic rankine cycle and other fields in recent years. In the work, some fundamental information about R1234ze(Z) was provided. At the same time, many researchers had investigated the heat transfer characteristic and frictional pressure drop of R1234ze(Z) for both the condensation and evaporation. The heat transfer coefficients of R1234ze(Z) are much higher than those of all the other refrigerants now used in heat pump application while the frictional pressure drop of R1234ze(Z) was a little higher than that of the conventional refrigerants. In conclusion, R1234ze(Z) is a very potential low-GWP and low-flammable refrigerant with high heat transfer coefficient while its frictional pressure drop is higher than conventional refrigerants. In this work, the saturation pressures of cis-1,3,3,3-tetrafluoropropene were investigated using two different apparatuses at temperatures rangingfrom 243.152 K to 373.150 K. The uncertainties of the temperature and pressure were less than 5 mK and 0.0007 MPa for one setups, and were less than 5 mK and 0.0005 MPa for another. The experimental data were compared with Fedele, Higashi, Katsuyuki and Refprop 9.1. Good agreements were found among them with the maximum deviation of 0.0016 MPa, and the maximum relative deviation of 1.07% comparing to Refprop 9.1. Using Antoine equation, Wagner equation and Helmholtz equation, the expermental data were regressed, and the average absolute relative deviation of the pressure are satisfactory. The relative deviation of the pressure were higher at lower temperature than that at higher temperature, due to the very low pressure at lower temperature. In the end, the Helmholtz equation was analyzed with various number of terms to regress the experimental data. An approximate linear correlation between the reduced pressure and the inverse reduced temperature was found by analyzing the dominant factor in the terms of the Helmholtz equation. The Helmholtz equation of three terms were good enough to represent the saturated vapor pressure of R1234ze(Z), and to get the best result, five terms were recommended in Helmholtz equation. The average absolute relative deviations of the pressures calculated by Wagner equation and Helmholtz equation with five terms are 0.3105% and 0.2813%, respectively.
