saturationPressure

Saturation pressure w.r.t. temperature

Information

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

This function calculates the saturation pressure of R134a from the state variable T (temperature). It is modelled by cubic splines which are fitted with non-equidistant grid points derived from the fundamental equation of state of Tillner-Roth and Baehr (1994) and the Maxwell criteria.

Restrictions

It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
