.Buildings.DHC.Loads.BaseClasses.PartialBuildingWithPartialETS

Information

Partial model to be used for modeling

• an energy transfer station and the optional in-building primary systems, based on a model extending Buildings.DHC.ETS.BaseClasses.PartialETS, and
• the served building, based on a model extending Buildings.DHC.Loads.BaseClasses.PartialBuilding.

See the schematics below for a description of the physical boundaries of the composing systems.

The parameters defining the set of outside connectors of this class are propagated up from the ETS and building components. The connect clauses between the ETS and the building connectors are automatically generated based on the previous parameters and the additional parameters nPorts_heaWat and nPorts_chiWat that need to be specified. In case of a heating service line, the model allows for using two different media at the inlet port_aSerHea and at the oulet port_bSerHea to represent a steam supply and condensate return.

Scaling

Scaling is implemented by means of a multiplier factor facMul. Each extensive quantity (mass and heat flow rate, electric power) flowing out through fluid ports, or connected to an output connector is multiplied by facMul. Each extensive quantity (mass and heat flow rate, electric power) flowing in through fluid ports, or connected to an input connector is multiplied by 1/facMul. This allows modeling, with a single instance, multiple identical buildings with identical energy transfer stations, served by the same service line.

• December 21, 2022, by Kathryn Hinkelman:
  Added conditional requirement have_pum to instance totPPum for cases where ETS and building both don't have pumping.
  This is for #2912.
