modelPartialPlant
Partial class for modeling a plant
Information
Partial class to be used for modeling a plant.
The connectors to the service lines are configured based on an enumeration
defining the type of district system, see
Buildings.DHC.Types.DistrictSystemType.
In case of a heating service line, the model allows for using two
different media at the supply port port_bSerHea and at the return
port_aSerHea to represent a steam supply and condensate
return.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | have_fue | nFue > 0 | Set to true if the plant has fuel use |

| Configuration | |||
| Buildings.DHC.Types.DistrictSystemType | typ | Buildings.DHC.Types.DistrictSystemType.CombinedGeneration2to4 | Type of district system |
| Boolean | have_fan | false | Set to true if fan power is computed |
| Boolean | have_pum | false | Set to true if pump power is computed |
| Boolean | have_eleHea | false | Set to true if the plant has electric heating system |
| Integer | nFue | 0 | Number of fuel types (0 means no combustion system) |
