R14

 

R14 provides thermodynamic and transport property information for refrigerant R14 (CF4, tetrafluoromethane, CAS #75-73-0).  The correlation for the thermodynamic properties is applicable for temperatures between 120 K and 620 K for mpressures up to 50 MPa.  The correlation is based on information from:

 

Platzer, B., Polt, A., and Maurer, G., "Thermophysical Properties of Refrigerants,"  Springer-Verlag, Berlin, 1990.

 

The reference state is NBP which sets the specific enthalpy and entropy to 0 for saturated liquid at the normal boiling point (145.1 K)

 

Viscosity has 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

 

Thermal conductivity is provided using correlations given in:

Yaws, Carl L., ed. Chemical Properties Handbook. New York: McGraw-Hill, 1999.

 

Surface tension data are provided using the information in:

Mulero, A., Cachadina, I, and Parra, M.

"Recommended Correlations for the Surface Tension of Common Fluids"
