The thermodynamic properties of refrigerant R11 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 values of specific enthalpy and entropy are referred to 0 for saturated liquid at -40 C (F).


Range of applicability for transport function correlations:

Gas-phase viscosity:  200 K to 380 K

Liquid-phase viscosity: 230 K to 500 K

Gas-phase thermal conductivity: 270 K to 420 K

Liquid-phase thermal conductivity: 235 K to 450 K
