Buildings.Experimental.DHC.EnergyTransferStations.Combined.Generation5.Validation.ChillerBorefield
Validation of the ETS model with heat recovery chiller and borefield
Information
This model validates Buildings.Experimental.DHC.EnergyTransferStations.Combined.Generation5.ChillerBorefield in a system configuration including a geothermal borefield. See Buildings.Experimental.DHC.EnergyTransferStations.Combined.Generation5.Validation.ChillerOnly for the description of the main modeling assumptions.
Extends from ChillerOnly (Validation of the ETS model with heat recovery chiller).

Modelica definition
Buildings.Experimental.DHC.EnergyTransferStations.Combined.Generation5.Validation.ChillerOnly
Validation of the ETS model with heat recovery chiller
Information
This model validates Buildings.Experimental.DHC.EnergyTransferStations.Combined.Generation5.ChillerBorefield in a system configuration with no geothermal borefield.
- A fictitious load profile is used, consisting in the succession of five load patterns.
- Each load pattern is simulated with two values of the district water supply temperature, corresponding to typical extreme values over a whole year of operation.
- The other modeling assumptions are described in Buildings.Experimental.DHC.EnergyTransferStations.Combined.Generation5.Validation.BaseClasses.PartialChillerBorefield.
Extends from BaseClasses.PartialChillerBorefield (Partial validation of the ETS model with heat recovery chiller and optional borefield).
