All HVAC Component windows are dual purpose windows allowing you to either Create a new HVAC Component element (by default) or Modify the attributes of an existing HVAC Component element.

Referring to the HVAC Hierarchy section, an HVAC Component must reside below an existing HVAC Branch element. For a detailed explanation of creating an HVAC Branch, see Create / Modify HVAC Main Branch, or refer to HVAC Side Branch.

Create an HVAC Component

The task of creating an HVAC Component is initiated from the HVAC Window.

  1. Select Rectangular in the Categories dropdown list and then Straight in the Available Type dropdown list to display the Straight window:

    Note: Make sure the dropdown list in the top left of the HVAC Component window is set to Create.

    You are required to input the following dimensions for the new HVAC Component.

    • Duct width AA

    • Duct depth AB

    • Length

  2. To visualize how the dimensions equate to the actual piece of HVAC select Picture to display a detailed drawing for Flat Oval Components Catalog Element - Straight.

    Note: The fields will be pre-populated with default dimensions. These dimensions are governed by the details defined in the HVAC Catalog.

  3. Select Transpose width/depth to exchange Duct Width AA dimensions with Duct depth AB dimensions.

  4. You can specify from a selection of industry standard joints, an Arrive Joint (Arrjoint) for the inlet side of the component and a Leave Joint (Leajoint) for the outlet side of the component by clicking Choose.

    The default for the Arrjoint value will be set to detailing specification, for further information on detailing specification, see Default Detailing Specification).

  5. When the Arrjoint is selected, select Prev.

    The software will then automatically select the Leajoint used on the adjacent piece of HVAC to use for the Arrjoint on the new piece of HVAC. If no adjacent piece of software exists an Error message will be displayed.

  6. To select an Arrjoint or Leajoint, select Choose to open the Choose Joint Window.
