This paper reports a correlation of dew- and bubble-point curves for seven binary refrigerant mixtures of engineering importance. The present correlations have been established based upon the reliable measurements of dew- and bubble-points by the present authors and others using a constant volume method. We have made the present correlation by calculating the differences between the experimental values and the calculated values due to Raoult's law. After correlating these differences ΔPd or ΔPb with temperatures, we represented these temperature terms in terms of the composition x_1 of the first Components which have lower critical temperature in binary components. It was confirmed that the present correlations for seven binary refrigerant mixtures were effective to model the dew- and bubble-point curves for any mixtures with an arbitrary composition, and to reproduce the dew- and bubble-point pressures even in the neighborhood of the critical points where the SRK equation did not reproduce the measured vapor-liquid equilibrium.
