Internal Damper

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

Select Rectangular in the Categories drop-down list and then Internal Damper in the Available Type drop-down list to display the Internal Damper window:

You are required to input the following dimensions:

• Duct Width AA

• Duct Depth AB

• Distance From Leave

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

To visualize how the dimensions equate to the actual piece of HVAC click Picture to display a detailed drawing for Internal Damper.

Click Transpose Width/Depth to exchange the Duct Width AA dimension with Duct Depth AB dimension.

In Handle Direction specify the axis to be used. Valid axes are E (East), N (North), U (Up), -E (negative East), -N (negative North) or -U (Negative Up).The Clash Vol fields will be pre-populated with the obstruction volumes associated with the access panel and the ducting, but can be changed by you.

In the Position list, select Connect or Unchanged:

• Click Connect (default when Create is selected) - connects the piece of HVAC to the previous one.

• Click Unchanged (default when Modify is selected) - positions the component at the co-ordinates 0.00.

  Note:
  Unchanged is usually used, when Modify is selected, it does not connect the component but positions it at 0.00, in effect in a floating position.

Click Defaults to reset all the fields back to when the Internal Damper window was opened.

Click Fit To Next to orientate the Internal Damper to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.
