Record with fitting coefficients taken from the Fast_Propane model

## Information

In this record, fitting coefficients are provided for thermodynamic properties calculated from two independent state variables. For detailed information of these thermodynamic properties as well as the fitting coefficients, please checkout AixLib.DataBase.Media.Refrigerants.ThermodynamicStatePropertiesBaseDataDefinition . The fitting coefficients are used in a hybrid refrigerant model provided in AixLib.Media.Refrigerants . For detailed information, please checkout AixLib.Media.Refrigerants.Interfaces.TemplateHybridTwoPhaseMediumRecord .

#### Assumptions and limitations

The provided coefficients are fitted to external data by Sangi et al. and are valid within the following range:

"Range of validiry" cellspacing="0" cellpadding="2" border="1" width="30%" style="border-collapse:collapse;">

Parameter | Minimum Value | Maximum Value
Pressure (p) in bar | 0.5 | 30
Temperature (T) in K | 263.15 | 343.15

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.
