modelMassFlowCharacteristicLines

Model for the specification of the heating water massflow at each feed-in point as a funcion of the total amount of heating water massflow
Diagram of MassFlowCharacteristicLines

Information

1. Purpose of model

Provides a practical interface to input the mass flow supplied by a given heating plant as a function of the total expected massflow.

2. Level of detail, physical effects considered, and physical insight

(Purely tabular component without physical modeling)

3. Limits of validity

(Purely tabular component without physical modeling.)

4. Interfaces

Real Input:

  • u[1] Total mass flow supplied to the district heating grid in kg/s

Real Output:

  • y[1]: Mass flow supplied by plant 1 in t/h
  • y[2]: Mass flow supplied by plant 2 in t/h
  • ...
  • y[n] Mass flow supplied by plant n in t/h

5. Nomenclature

(no elements)

6. Governing Equations

(no equations)

7. Remarks for Usage

This component was created using the combiTable 1Ds of the MSL. For further information regarding its usage refer to that component.

Create a text file with the following structure:


#1

double default(n-rows, m-columns) #Comment: u[1] y[1] y[2]

xx xx xx

xx xx xx

xx xx xx



In the parameter "columns" write for instance {2, 3} (meaning that the 2nd and third columns will be used and assigned to the outputs y[1] and y[2]).

8. Validation

(no validation or testing necessary)
