.Annex60.Fluid.Interfaces.PrescribedOutletState

Information

This model sets the temperature of the medium that leaves port_a to the value given by the input TSet, subject to optional limitations on the heating and cooling capacity.

In case of reverse flow, the set point temperature is still applied to the fluid that leaves port_b.

If the parameter energyDynamics is not equal to Modelica.Fluid.Types.Dynamics.SteadyState, the component models the dynamic response using a first order differential equation. The time constant of the component is equal to the parameter tau. This time constant is adjusted based on the mass flow rate using

τeff = τ |ṁ| ⁄ ṁnom

where τeff is the effective time constant for the given mass flow rate and τ is the time constant at the nominal mass flow rate nom. This type of dynamics is equal to the dynamics that a completely mixed control volume would have.

This model has no pressure drop. See Annex60.Fluid.HeatExchangers.HeaterCooler_T for a model that instantiates this model and that has a pressure drop.
