.Buildings.Fluid.DXSystems.Cooling.AirSource.MultiStage

Information

This model can be used to simulate an air source DX cooling coil with multiple operating stages. Depending on the used performance curves, each stage could be a different compressor speed, or a different mode of operation, such as with or without hot gas reheat.

See Buildings.Fluid.DXSystems.Cooling.UsersGuide for an explanation of the model.

Revisions

• March 19, 2023 by Xing Lu and Karthik Devaprasad:
  Renamed class to MultiStageCooling to differentiate it from DX heating coils.
  Extended class changed to Buildings.Fluid.DXSystems.Cooling.BaseClasses.PartialDXCoolingCoil.
  Updated connection statements because of coil capacity block instance being renamed from dxCoo to dxCoi.
  Updated formatting for readability.
• March 7, 2022, by Michael Wetter:
  Set final massDynamics=energyDynamics.
  This is for #1542.
• September 6, 2012 by Michael Wetter:
  Changed control signal from a real number to an integer that is equal to the stage of the coil. Removed filter at the control input signal because there is anyway an event when the signal changes, and because the filter led in Buildings.Fluid.DXSystems.Examples.SpaceCooling to a higher computing time.
• July 28, 2012 by Kaustubh Phalak:
  First implementation.
