Rectangular Grille in Line

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

Select Inline Plant Equipment in the Categories drop-down list and then RECTANGULAR, Grille in line in the Available Type drop-down list to display the In line Grille window:

You are required to input the following dimensions:

• UNIT Name(Ref)

• Duct Width AA

• Duct Depth AB

• End Width

• End Depth

• Grille Length

• ‘A’ Extension

• Fixing to Duct

• End Joint

• End Joint Width

• End Joint Depth

• End Joint Thickness

To visualize how the dimensions equate to the actual piece of HVAC, click Picture to display a detailed drawing for Rectangular Grille (in line).

Note:
The fields will be pre-populated with default dimensions. These dimensions are governed by the details defined in the HVAC Catalog. The Fixing to Duct joint default is joint defined in the HVAC Catalog but can be changed by you to the required joint.

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

Click Transpose Width/Depth to exchange End Width dimension with the End Depth dimension.

In the Width Direction specify the axis that should be used. Valid axes are E (East), N (North), U (Up), -E (negative East), -N (negative North) or -U (Negative Up).

The Clash Vol OUT field is pre-populated with the obstruction volume associated with the In line Grille and the ducting.

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 In line Grille window was opened.

Click Fit to orientate the In line Grille to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

Click OK to create the In line Grille component and close the In line Grille Window. You will be returned to the HVAC Window.

Click Cancel to discard all the field changes and close the In line Grille window.
