P5: Process Heat Heat Exchanger (WT)

Procedure:

  1. Navigate to the Demand page.
  2. Specify a Label for this process heat heat exchanger.
  3. Enter the average daily demand either as volume or energy. The resulting annual demand and the maximum expected hourly demand will be displayed.
  4. Specify:
    • the desired supply temperature
    • the return temperature
  5. Consumption Profile: The annual profile of energy demand for process heat is determined using qualitative, hourly consumption profiles. Use Select to choose a consumption profile.
  6. Adjust the Parameters of the consumption profile to match your requirements. The consumption profile dialog works the same way as for hot water consumption profiles.
  7. Confirm your adjustments with OK, then close this dialog to return to the Process Heat WT dialog.
  8. Go to the Operating Hours page.
  9. Define the operating hours throughout the year.
  10. Proceed to the Heat Exchanger page.
  11. Select a heat transfer quality. Details can be found under External Heat Exchanger.
  12. Move on to the Connection page.
  13. Determine whether there is a return flow mixing.
  14. Specify the simple pipe length for connecting to the heat network and the specific heat losses.
  15. Confirm with OK or proceed with .

A13, A14.X: Process Heat Consumer with Storage

Variant Menu: Settings > Process Heat > Parameters or Variants Menu: System Definition > Process Heat

System types A13 and A14.X are equipped with the process heat consumer type, which has definable supply and return temperatures.

Procedure:

  1. Go to the Parameters page.
  2. Enter the average daily energy demand. The resulting annual demand and the maximum expected hourly demand will be displayed.
  3. Specify:
    • the desired nominal supply temperature
    • the minimum supply temperature at which the consumer starts operating or up to which the supply temperature may drop below the set temperature
    • the return temperature
  4. Consumption Profile: The annual profile of energy demand for process heat is determined using qualitative, hourly consumption profiles. Use Select to choose a consumption profile.
  5. Adjust the Parameters of the consumption profile to match your requirements. The consumption profile dialog works the same way as for hot water consumption profiles.
  6. Confirm with OK, then close this dialog to return to the Process Heat dialog.
  7. Confirm with OK or proceed with .

A15: Process Heat with 100% Coverage

System A15: Process Heat without Storage: Dialog > Process Heat with 100% Coverage > Parameters

In addition to the consumer with a predefined energy consumption, there is also system type A15 without a storage tank, where energy is extracted from the collector field as soon as the supply temperature exceeds the return temperature. This allows for an investigation into how much energy the solar system could deliver under these conditions.

  • Specify:
    • Return temperature
    • constant volume flow
