The thermodynamic properties of the azeotropic refrigerant mixture R500 (73.8% R12, 26.2% R152a by mass) are provided by Martin-Hou equation of state (A.I.Ch.E. Journal, 1:142, 1955). Fitted parameters are from Downing and Knight, DuPont Technical Bulletin RT-52, 1971.
The reference state is determined by setting specific enthalpy and entropy of saturated liquid to 0.
Range of applicability for transport function correlations:
Gas-phase viscosity: 240 K to 390 K
Liquid-phase viscosity: 200 K to 370 K
Gas-phase thermal conductivity data are not implemented
Liquid-phase thermal conductivity" 290 K to 335 K
