Buildings.Templates.Plants.HeatPumps.Components.Validation.HeatPumpGroupAirToWater
Validation model for heat pump group with AWHP
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.HeatPumpGroups.AirToWater in a configuration in which the heat pump group components are exposed to a constant differential pressure and a varying return temperature.
The model is configured to represent either a non-reversible heat pump group
(component hpAwNrv) or a reversible heat pump group (component
hpAw) that switches between cooling and heating mode.
Extends from Modelica.Icons.Example (Icon for runnable examples).

Buildings.Templates.Plants.HeatPumps.Components.Validation.HeatPumpGroupAirToWaterPolyvalent
Validation model for AWHP group with polyvalent HP
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.HeatPumpGroups.AirToWater in a configuration in which the heat pump group components are exposed to a constant differential pressure and a varying return temperature.
The model is configured to represent either a single polyvalent HP without
reversible heat pumps (component php) or a group of reversible
heat pumps with a single polyvalent HP (component hpPhp).
Extends from Modelica.Icons.Example (Icon for runnable examples).

Validation model for heat recovery chiller
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.HeatRecoveryChiller.
The CHW and HW return temperatures and flow rates are at their design values. The HRC supply temperature setpoint is switched from the design CHW supply temperature to the design HW supply temperature when the HRC operating mode is switched from cooling to heating.

Buildings.Templates.Plants.HeatPumps.Components.Validation.PumpsPrimaryDedicated
Validation model for dedicated primary pump component
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.PumpsPrimaryDedicated for the following configurations.
-
Reversible heat pumps with a single dedicated primary pump serving both
CHW and HW circuits: component
pumPriCom. -
Reversible heat pumps with headered constant speed primary pumps:
component
pumPriHdr. -
Reversible heat pumps with separate constant speed dedicated HW and CHW
pumps: component
pumPriSep. -
Heating-only heat pumps with variable speed dedicated primary pumps:
component
pumPriHea.
In each configuration, two identical heat pumps are represented by fixed
flow resistances (components hp*).
The model uses open loop controls and the simulation allows verifying that design flow is obtained in each loop and each heat pump when the pumps are enabled.
In the configuration with a single dedicated primary pump serving both CHW
and HW circuits, this requires adjusting the design pressure drop of the
balancing valves which are modeled by fixed flow resistances in the
isolation valve components valHeaWatIsoCom and
valChiWatIsoCom. This adjustment is done programmatically using
the function
Buildings.Templates.Utilities.computeBalancingPressureDrop.
Similarly, in the configuration with variable speed pumps
pumPriHea, the design head of the pumps is voluntarily chosen
higher than necessary and the required pump speed needed to provide the
design HP flow is computed at initialization by solving for a balancing
valve pressure drop of zero. Note that this requires solving a numerical
Jacobian at initialization. Although this is handled well by various
Modelica tools, the parameter use_spePumIni allows switching to
a default value in this validation model for better integration into the
continuous integration test workflow.

Buildings.Templates.Plants.HeatPumps.Components.Validation.PumpsPrimaryDedicatedPolyvalent
Validation model for dedicated primary pump component with polyvalent heat pumps
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.PumpsPrimaryDedicated for the following plant configurations.
-
Heat pumps with a single dedicated primary pump serving both CHW and HW
circuits, polyvalent units with constant speed dedicated primary pumps:
component
pumPriCom. -
Plant with headered constant speed primary pumps: component
pumPriHdr. -
Plant with separate constant speed dedicated HW and CHW pumps: component
pumPriSep.
In each configuration, two identical heat pumps and two identical polyvalent
units are represented by fixed flow resistances (components
hp*, phpCon* and phpEva*).
The model uses open loop controls and the simulation allows verifying that design flow is obtained in each loop and each unit when the pumps are enabled.
In the configurations with headered pumps, or with a single dedicated
primary pump serving both CHW and HW circuits, this requires adjusting the
design pressure drop of the balancing valves which are modeled by fixed flow
resistances in the isolation valve components valHeaWatIso* and
valChiWatIso*. This adjustment is done programmatically using
the function
Buildings.Templates.Utilities.computeBalancingPressureDrop.

Buildings.Templates.Plants.HeatPumps.Components.Validation.ValvesIsolation
Validation model for isolation valve component
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.ValvesIsolation for the following configurations.
-
Heating and cooling system with common dedicated primary HW and CHW pumps
and isolation valves at both heat pump inlet and outlet: component
valIsoCom. -
Heating-only system with isolation valves at heat pump inlet: component
valIsoHeaInl. -
Heating and cooling system with separate dedicated primary HW and CHW
pumps and isolation valves at heat pump inlet: component
valIsoSep.
In each configuration, two identical heat pumps are represented by fixed
flow resistances (components hp*).
Open-loop controls are used throughout. The simulation allows verifying that design flow is achieved in each loop and each heat pump when the valves are open and the primary pumps are on.
Extends from Modelica.Icons.Example (Icon for runnable examples).

without isolation valves: component
valIsoCom. -
AWHP with isolation valves at the inlet only, polyvalent units with
isolation valves at the outlet only: component
valIsoSep.
Open-loop controls are used throughout. The simulation allows verifying that the design flow rate is achieved in each unit when the isolation valves are open and/or the primary pumps are on.
