Information

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

This function calculates the Kelvin temperature of R134a from the state variables p (absolute pressure) and h (specific enthalpy). The temperature is modelled by the fundamental equation of state of Tillner-Roth and Baehr (1994).
