Fluid Phase Equilibria | 1998

Thermodynamic properties of HFC-143a (1,1,1-trifluoroethane)

Chun-cheng Piao; Katsuki Fujiwara; Masahiro Noguchi

Abstract An equation of state for HFC-143a has been developed based on available experimental data. The equation of state presented here for HFC-143a is valid both in the superheated gaseous phase and compressed liquid phase at pressures up to 35 MPa, densities to 1327 kg/m3, and temperatures from the triple point temperature of 161.34 K to 433 K. Correlations of the ideal gas heat capacity, vapor pressure and saturated liquid density are also presented.
