Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This function calculates the isobaric expansion coefficient of R134a from the state record (e.g., use setState_phX function for input). The isobaric expansion coefficient is modelled by the fundamental equation of state of Tillner-Roth and Baehr (1994).

Restrictions

This property is only defined in one-phase region.
