Thermodynamic property data for pressure p and specific enthalpy h as dynamic states
Extends from Modelica.Icons.Record (Icon for records).
Information
Model description A base class for medium property models which use pressure and enthalpy as dynamic states. This is the preferred model for fluids that can also be in the two phase and liquid regions. ## Copyright © EDF 2002 - 2025 ## ThermoSysPro Version 4.2
