Condenser Loops

Location = Templates/System Templates/Condenser Loops

 

Portions of the cooling side of the HVAC system can be provided by the condenser water loop(s) configuration.  A complete condenser water loop is composed of a supply side and a demand side.  The supply side is composed of different component shapes that are connected together and contain the required properties so that EnergyPlus can run effectively.  In addition, controllers can be connected to a number of different components, which allows a range control types and schemes to be introduced into the water loop.  When working in the condenser water loop template workspace you can create the supply side of the condenser water loop.  Once a condenser water loop template has been saved to the source library it is an option for you to select when you are creating a condenser water loop in your model in the Systems: Condenser Water Loops Create/Edit workspace.  The demand side of the chilled water loop can only be created in the Systems:Diagram workspaces.  It cannot be created in the Templates workspace and saved with a Chilled Water Loop Template.

 

The Condenser Loops workspace is broken down into six main areas described in the System Templates Workspace, and is very similar in composition and capabilities to the Water Loops Create & Edit Workspace.  In addition, the Condenser Loop System Templates workspace is similar to the Hot Water, Chilled Water and Mixed Water Loop System Templates workspaces.   The user can visualize, edit and create new Condenser Loop diagrams.

 

The following provide more detailed information for the main areas, and the features within them.
  

System Template Naming/Selection Area - the drop down list where the templates from the active source library can be selected, and descriptions can be associated with each template as well.

Chilled Water Loop Parameters Area - the properties that can be set at the overall loop level

Component Properties - the properties that appear in the lower left when a component shape is selected in the HVAC Diagramming Canvas

Stencils - include the component, controller and sensor shapes that can be dragged and dropped onto the HVAC Diagramming Canvas to create or edit the templates

HVAC Diagramming Canvas - the loop creation playground where the component shapes can be dragged and dropped onto, different components can be connected, components selected to edit properties and other features.

Loop Level Controls - displays the current Condenser Operation Schemes and Availability Managers that are defined for the template.  

Validation - The location where the error messages are displayed after the Chilled Water Loop Ruleset has been run (Validate)

 

Condenser Water Loop System Templates

The table displays the Condenser Water Loop System Templates that are included with version 1.    The Condenser Water Loop System Templates utilize a naming convention, so that the names can be represented in an abbreviated manner.  

Note: Condenser water templates can be edited and resaved or copied, edited and saved as new templates.
