Inline Equipment Components - Rectangular Centrifugal Fan r

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

1. Select Inline Plant Equipment in the Categories dropdown list.

2. Select Centrifugal Fan r in the Available Type dropdown list to display the Centrifugal Fan window:

   Note: A centrifugal fan can only be created as the first item in a HVAC branch.

   

3. Centrifugal Fans can be left or right handed, from the Type dropdown list, select Left or Right.

   You are required to input the following dimensions:

   • Name(Ref)

   • Rect width AA

   • Rect depth AB

   • Circular Diameter

   • Centrifugal Fans can be left or right handed, from the Type dropdown list, select Left or Right.

   • Outside Diameter

   • Centreline Height

   • Circ Extension

4. To visualize how the dimensions equate to the actual piece of HVAC, select Picture to display a detailed drawing for Inline Plant Equipment Catalog - Centrifugal Fan.

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

5. Select Transpose width/depth to exchange Rect width AA dimension with the Rect depth AB dimension.

6. Specify a type of joint to use for the Rect Jnt (Rectangular Joint) and Circ Jnt (Circular joint). For a detailed description, see Create / Modify HVAC Components.

7. After selecting the type of joint to use for the Rect Jnt and Circ Jnt, enter the Circ Direction.

8. In the Circ 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). X, Y, Z, -X, -Y or -Z.

9. In the Connect list, select Connect or Unchanged:

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

   • Select Unchanged (default when Modify is selected) - positions the piece of HVAC at the co-ordinates 0.00.

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

10. Select Defaults to reset all the fields back to when the Centrifugal Fan window was opened.

11. Select Fit to orientate the Centrifugal Fan to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

12. Select OK to create the Centrifugal Fan component and close the Centrifugal Fan Window. You will be returned to the HVAC Window.

13. Select Cancel to discard all the field changes and close the Centrifugal Fan window.
