The reference point is defined as 200 kJ/kg and 1 kJ/kg/K, respectively, for enthalpy and entropy for the saturated liquid at 273.15 K.

Validation

The model is validated by comparing results obtained from the example model AixLib.Media.Refrigerants.Examples.RefrigerantProperties to external data (e.g. obtained from measurements or external media libraries).
