Equations obtained are in the form of polynomials in terms of saturation temperature. Correlations proposed include saturation pressure P (T), saturated liquid specific volume v{sub}f (T) and density D{sub}1 (T), saturated vapour specific volumev{sub}0 (T), saturated liquid specific enthalpy h{sub}f (T), saturated vapour specific enthalpy h{sub}0 (T), specific enthalpy of vaponzation h{sub}f0 (T), saturated liquid specific entropy s{sub}f (T), saturated vapour specific entropy s{sub}0(T) andspecific entropy of vaporization s{sub}f0(T). Equations produced are compared with the data given in Tables. Errors in the calculated values of the above properties are also tabulated. Figures show the fitted curves. The calculations are simple, andcomputationally fast:for commonly encountered refrigeration conditions predicted properties generally agree with the source data.
