The thermodynamic properties of refrigerant R11 (trichlorofluoromethane, CFCl3, CAS# 75-69-4) are provided with a reduced Helmholtz equation of state as described by:


R.T Jacobsen, S.G. Penoncello and E.W. Lemmon

"A Fundamental Equation for Trichlorofluoromethane (R-11)"

Fluid Phase Equilibria, 80 (1992) 45-56


The values of specific enthalpy and entropy are referred to 0 for saturated liquid at -40 C (F).  The reference state can be changed using the $Reference directive.



Viscosity and thermal conductivity have been estimated using a corresponding states approach with propane as the reference fluid as suggested in:

Klein, S.A., McLinden, M.O., and Laesecke , A., "An improved extended corresponding states method for estimation of viscosity of pure refrigerants and mixtures'

Int. J. of Refrigeration, 20, pp. 208-217, 1997


McLinden et al., "An extended corresponding states model for the thermal conductivity of refrigerants and refrigerant mixtures",

Int. J. of Refrigeration, 23, pp. 43-63, 2000


The estimated transport properties should be applicable for the range in which the equation of state is valid.


Surface tension data are provided using the information in:
