The thermodynamic properties of the azeotropic refrigerant mixture R502 (48.8% R22, 51.2% R115 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: 220 K to 390 K
Liquid-phase viscosity: 200 K to 350 K
Gas-phase thermal conductivity: 225 K to 380 K
Liquid-phase thermal conductivity: 280 K to 320 K
