Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates the specific Helmholtz energy of R134a from the state record (e.g., use setState_phX function for input). The Helmholtz energy is modelled by the fundamental equation of state of Tillner-Roth and Baehr (1994).
