modelHeatflow_L1_idContrQFlow_temp
Extends from Base.Heatflow_L1_idContr_temp_base (Base class for heat flow boundaries with ideal control to get a given outlet temperature).
Information
1. Purpose of model
This model is a heat flow boundary which calculates the heat flow rate to get a given outlet temperature. It can be chosen if the outlet set temperature is constant or given by an input.
2. Level of detail, physical effects considered, and physical insight
The heat flow rate is calculated based on the given mass flow rate at the ports and a given constant outlet temperature. There is no volume considered.
There are no pressure losses included.
The model calculates any heat flow rate that is necessary to reach the given temperature. So, there are no heat flow rate limits and no limitations in regard of flow direction (positive/negative).
3. Limits of validity
This model is only valid for ideal controls, i.e. ideally tuned controls with no control errors.
4. Interfaces
T_out_set: set point for outlet temperature
fluidPortIn: inlet for fluid
fluidPortOut: outlet for fluid
5. Nomenclature
(no elements)
6. Governing Equations
(no equations)
7. Remarks for Usage
The model is only working properly in design flow direction. Reverse flow is not supported!
8. Validation
(no validation necessary)
9. References
