For detailed information of these thermodynamic properties as well as the fitting coefficients in general, please checkout AixLib.DataBase.Media.Refrigerants.BubbleDewStatePropertiesBaseDataDefinition . 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 Engelpracht
