General Tab

Initial and end nodes – Specifies the linkage of the supplier within the network between the initial and end nodes. With the combination fields the linkages can be formed to existing nodes in the network.

Zone – Allocates a supplier to one of the zones configured.

✍ The allocation is insignificant for actual hydraulic calculation. It is useful in the case of the formation of network variables for cost calculations.

Const. Pressure Drop – Contains the constant pressure loss proportion caused by the supply – Δpconst .

Max. Pressure Loss – Max. pressure loss which occurs with the max. supplier mass flow – Δp.

Max. Supply Mass Flow – Contains the max. feed mass flow – m.

Pressure Drop Coefficient – The pressure loss coefficient φ displays the pressure loss related to the mass flow and enters the calculation of the feed pressure loss as follows:

Limits Tab

Max. Supply temperature – Contains the maximum entry temperature of the supply.

Max. Supply performance – Contains the maximum feed temperature of the supply.

Min. Supply Mass flow – Contains the minimum mass flow which the supplier is set for.

Heat generation costs – Contains the costs for heat production by the supply.

Capital outlays – Enter the capital outlays of the supply here.

Results Tab

You can access the calculation results for the supply using this tab. The height of the dialog mask is adaptable to be able to show the results list completely.

• Calculation – Indicates the names of the network calculation to which the results belong.
• List of the results – The following results for the supply are computed and indicated subject to the module:
• Size – Description
  • Exit pressure – Exit pressure and/or supply pressure for the categories gas and water.
  • Exit temperature – Feed temperature of the supply, only for the categories long-distance heating and long-distance cooling.
  • Feeding performance – Calculated heat performance of the supply.
  • Mass flow – Feed mass throughflow.
  • Flow rate – Feed volume throughflow.
  • Pressure loss – Hydraulic pressure loss of the supply.
  • Input pressure – Pressure at the entry flow of the supply.
  • Input temperature – Entry temperature of the supply, only for the categories long-distance heating and long-distance cooling.
  • Error – The description of the errors if any occur.
