Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This function calculates the time derivative of liquid specific enthalpy of R134a with regard to the time derivative of p. The non-derivative function is bubbleEnthalpy.
Restrictions
It is only valid in the two-phase region (i.e., ptriple ≤ p ≤ pcrit ).
