modelPartialDXCoil

Partial model for air or water cooled DX cooling coil

Extends from Buildings.Fluid.DXSystems.Cooling.BaseClasses.EssentialParameters, Buildings.Fluid.Interfaces.TwoPortHeatMassExchanger.

Information

This partial model is the base class for Buildings.Fluid.DXSystems.Cooling.BaseClasses.PartialDXCoolingCoil.

Parameters

TypeNameDefaultDescription
Booleanuse_mCon_flowSet to true to enable connector for the condenser mass flow rate
Dynamics › Moisture balance
BooleancomputeReevaporationtrueSet to true to compute reevaporation of water that accumulated on coil

Components

Revisions

  • March 19, 2023, by Xing Lu and Karthik Devaprasad:
    Changed baseclass to create common version for both heating and cooling coils.
    Renamed TConIn to TOut.
    Moved instances QLat_flow and eva to Buildings.Fluid.DXSystems.Cooling.BaseClasses.PartialDXCoolingCoil.
  • June 19, 2017, by Michael Wetter:
    Added missing replaceable to the medium declaration.
    This is for issue Buildings #810.
  • April 12, 2017, by Michael Wetter:
    Removed temperature connection that is no longer needed.
    This is for issue Buildings #704.
  • February 27, 2017 by Yangyang Fu:
    Added redeclare for the type of cooCap in dxCoiOpe.
  • May 6, 2015 by Michael Wetter:
    Added prescribedHeatFlowRate=true for vol.
  • August 31, 2013, by Michael Wetter:
    Updated model due to change in Buildings.Fluid.BaseClasses.IndexMassFraction.
  • September 24, 2012 by Michael Wetter:
    Revised documentation.
  • September 4, 2012 by Michael Wetter:
    Moved assignments to declaration section to avoid mixing graphical modeling with textual modeling in equation section. Redeclare medium model as Modelica.Media.Interfaces.PartialCondensingGases to remove errors during model check. Added output connectors for sensible and latent heat flow rate.
  • April 12, 2012 by Kaustubh Phalak:
    First implementation.
