Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Fan resp. pump with constant pressure increase. Mass resp. volume flow is the response of the whole system.
Coolant's temperature and enthalpy flow are not affected.
Setting parameter m (mass of medium within fan/pump) to zero leads to neglect of temperature transient cv*m*der(T).
Thermodynamic equations are defined by BaseClasses.TwoPort.
