modelValvesIsolation
Validation model for isolation valve component
Extends from Modelica.Icons.Example (Icon for runnable examples).
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*).
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 valves are open.
