Circ Air Displacement Unit

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

Select Extra Inline Equipment in the Categories drop-down list and then Circ Air Displacement Unit in the Available Type drop-down list to display the Air Displacement Unit window:

The Air Displacement Unit window default is a standard stock size, but can be changed by you using one of the following methods:

Standard Stock Sizes

In the Name(Ref) field, input the name of the HVAC component.

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

To choose from the standard stock sizes available from the HVAC Catalog, in the Stock Size drop-down list, click the required size for the HVAC component.

In the Front 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 Diameter field is pre-populated with the obstruction volumes associated with the Air Displacement Unit and the ducting.

Non Standard Stock Sizes (Special)

If you chose not to use a standard stock piece of HVAC, from the Stock Size drop-down list, click Special.

You are required to input the following dimensions:

• Name(Ref)

• Duct Diameter

• Body Diameter (A)

• Body Length (B)

• Arrive Extension

To visualize how the dimensions equate to the actual piece of HVAC, click Picture to display a detailed drawing for Circular Air Displacement Unit.

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

Specify a type of joint to use for the Arrive Joint. Refer to Create/Modify HVAC Component for a detailed description.

After selecting the type of joint to use for the Arrive Joint, you must enter the Front Direction.

In the Front 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 ClashVol Diameter field is pre-populated with the obstruction volume associated with the Circ Air Displacement Unit component 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 Air Displacement Unit window was opened.

Click Fit to orientate the Air Displacement Unit 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 Air Displacement Unit component and close the Air Displacement Unit Window. You will be returned to the HVAC Window.

Click Cancel to discard all the field changes and close the Air Displacement Unit window.
