modelWithDHW

ETS connected to building loads without DHW

Extends from Buildings.DHC.Examples.Combined.ETSHeatRecoveryHeatPump_BuildingTimeSeries.WithoutDHW (ETS connected to building loads without DHW).

Information

Validation model for a single building load, modeled as time series, connected to an ETS that has domestic hot water integration.

Note the following:

  • The model does not contain a district loop. Rather, the service line is connected to a constant pressure boundary, and the example model contains an energy transfer station connected to a building load.
  • The information that a domestic hot water integration is present is obtained from the load profile filNam by reading its entry for the peak domestic hot water load. As it is nonzero, the parameter bui.have_hotWat is set to true.

This model is identical to Buildings.DHC.Examples.Combined.ETSHeatRecoveryHeatPump_BuildingTimeSeries.WithoutDHW, except that it has domestic hot water.
