 Figure 4.5.3 - Connecting diffusers to an air handling unit |
Student Exercise
- Place six supply diffusers for an exposed HVAC system in the retail space at the north end of level 1 around the front façade.
- Create a supply system for the diffusers placed in the previous step:
- For the main ducts, use oval ducts with gored elbows/tapsand an offset of 13'-0" (3.96 m).
- For the branch ducts, use round ducts with tees, an offset of 13'-0"(3.96 m), and round flex ductswithmaximum flex duct length of 6'-0"(1.83 m).

Exercise 4.5.3: Modeling Closed Plenum HVAC Systems
|
In this exercise, students will learn how to:
|
 Figure 4.5.5 - Using auto-routing to place supply side ducts in closed plenum HVAC system |
Student Exercise
- Open the model for this exercise in Revit MEP software.
- Place two supply diffusers for a closed plenum HVAC system in the office space at the northeast corner of level 2.
- Place a variable air volume (VAV) unit above the corridor outside the office.
- Create a supply system for the diffusers and VAV unit placed in the previous steps using the Generate Layout tool:
- For the main ducts, use rectangular ducts with mitered elbows/teeswith an offset: 11'-0" (3.35 m).
- For the branch ducts, use rectangular ducts with mitered elbows/teeswith an offset: 11'-0" (3.35 m) and no flex duct.
- Open the 3D HVAC Lighting Coordination view to confirm that there are no conflicts between the HVAC elements and the lighting fixtures.
