Combination of storage tank, solar collector, controller and gas boiler. Stratified storage tank is divided into five layers: top layer is heated by boiler to T_boiler. Energy for space heating is extracted from two top layers, energy for DHW from all five layers. Solar energy is fed into bottom to second layer.
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
(no remarks)
5. Nomenclature
(no elements)
6. Governing Equations
(no equations)
7. Remarks for Usage
All components use energy based modeling without consideration of fluid flow.
Heat flow into the storage tank is based on the difference between the temperature of each tank level and the respective source or sink temperature.
Electric energy for the pumps is not accounted for.
8. Validation
(no validation or testing necessary)
