recordTSP_IIR_P05_30_T263_343
Extends from AixLib.DataBase.Media.Refrigerants.ThermodynamicStatePropertiesBaseDataDefinition (Base data definition for fitting coefficients of thermodynamic state properties).
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:
|
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.
