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, R13, R14, R22, R23, R113, R114, R500 and R502 are presented. High accuracy of results was achieved in comparing with ASHRAE tables. All equations are in SI units.  相似文献
