Summary

An equation of state for an environmentally acceptable refrigerant, R123, was developed, based on the available thermodynamic property data. It is a non-dimensionalized virial equation of state which has 21 coefficients and is effective in the entire fluid phase of pressures up to 15 megapascals, temperatures from 270 to 550 K, and densities from 0 to 1,600 kg/m3, respectively. The equation represents the reliable PVT measurements within more or less 0.5% in pressure for the superheated gaseous and supercritical fluid phase, while within more or less 0.5% in density for the compressed liquid phase. The vapour pressures and other essential thermodynamic properties were derived from the present modelling. Detailed discussions on the results compared with other measured data are also reported.
