R114 provides thermodynamic and transport property information for refrigerant R114 (C2F4Cl2, 1-2-diChloro-1,1,2,2 tetrafluoroetane, CAS #76-14-2). The correlation for the thermodynamic properties is applicable for temperatures between 273.15 K and 507 K for pressures up to 20 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 determined by setting specific enthalpy and entropy of saturated liquid to 0 at the normal boiling point (276.7 K).
Viscosity and thermal conductivity have been estimated using a corresponding states approach with propane as the reference fluid as suggested in:
