Record with fitting coefficients calculated for first implementation

Extends from AixLib.DataBase.Media.Refrigerants.ThermodynamicStatePropertiesBaseDataDefinition.

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 Engelpracht and are valid within the following range:
