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