modelElectricBoilerImpedance
Extends from TransiEnt.Basics.Icons.Model (Icon for models).
Information
1. Purpose of model
Model of an electrode boiler with impedance using TransiEnt interfaces and TransiEnt.Statistics. Heat transfer is ideal, thermal losses are modeled using a constant efficiency. Heat port or fluid ports are choosable.
2. Level of detail, physical effects considered, and physical insight
L1E
3. Limits of validity
(Purely technical component without physical modeling.)
4. Interfaces
epp: electric power port
fluidPortIn: fluid inlet (if selected)
fluidPortOut: fluid outlet (if selected)
heat: heat port (if selected)
Q_flow_set: set value for heat flow rate
5. Nomenclature
(no elements)
6. Governing Equations
