modelExpansionValvePressureDifference
Simple model to check different flow coefficient models with fixed inlet
and outlet states
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This is a simple example model to test expansion valves presented in AixLib.Fluid.Actuators.Valves.ExpansionValves.SimpleExpansionValves. Therefore, both the valve's inlet and outlet conditions are prescribed in terms of pressure and temperature.
