✦ Synopsis

The publication presents a set of equations and constants for calculating thermodynamic properties of refrigerants. State equation, equation of saturated vapor pressure, equation of liquid volume, equation of specific heat capacity, enthalpy and entropy for R11, R12, RI3, R14, R22, R23, RI 13, R114, RS00 and R502 are presented. High accuracy of results was achieved in comparing with ASHRAE tables. All equations are in SI units. NOMENCLATURE c~ specific heat capacity for ideal gas [J kg-JK -l ] H specific enthalpy [J kg-t ]

Many zeotropic refrigerant mixtures are being proposed as alternatives to CFCs and HFCFs refrigerants that are being phased out. The main advantage in the use of zeotropic mixtures is the possibility of reduction in entropy generation in the condenser and evaporator by matching the glides of refrige
