modelElectricBoiler
Extends from TransiEnt.Basics.Icons.Model (Icon for models).
Information
1. Purpose of model
Model of an electrode boiler 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
(Purely technical component without physical modeling.)
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 (if selected)
P_el_set: set value for electric power (if selected)
Q_flow_gen: generated heat
5. Nomenclature

10. Version History
Model created by Pascal Dubucq (dubucq@tuhh.de) in October 2014
Model generalized for different electrical power ports by Jan-Peter Heckel (jan.heckel@tuhh.de) in July 2018
Model modified (added selectable heat port) by Carsten Bode (c.bode@tuhh.de), Nov 2018
Model modified by Anne Hagemeier (anne.hagemeier@umsicht.fraunhofer.de) in July 2021 (added change_sign and option to deselect both fluid and heat ports)
