duct(HVAC) refer to transfer of air between spaces in a building.

principles of thermodynamics, fluid mechanics, and heat transfer.

systems can provide ventilation, reduce air infiltration, and maintain
pressure relationships between spaces.
duct is manufactured from sheet steel and is manually turned to the
desired diameter using a forming gauge and then welded. The welding
component is the most crucial part of the process, ensuring the
productís reliability and longevity.
duct design includes honeycomb core inserts to produce a stiffened duct
wall. The honeycomb core is filled with closed cell foam to assure that
resin will not fill the cell walls. Reinforcing keel straps were also
selectively laid up into the duct structure.
Properly sealing ductwork results in several benefits. It improves
comfort by increasing the rate at which air is delivered to a space.
most cost-effective time to seal ducts is when an HVAC system is first
installed in new construction, because the ducts are easily accessed.
However, ductwork can also be sealed in existing buildings.
flexible ducts are either inserted by: manually inserting a flexible in
between 2 duct openings; making the diffuser settings to insert flex
ducts as diffuser connections.
Selection of sealants that do not fail within the lifetime of the duct
system requires the existence of relative ratings for sealant longevity.
Company in has manufactured a prototype engine-inlet duct using a
low-cost VaRTM (Vacuum-assisted Resin Transfer Molding) and braiding
process under the auspices of the Air Force Composite Affordability
Initiative (CAI) program.
advanced-design duct features a foreshortened, compact geometry with low
complicated shape creates manufacturing challenges, and the objective of
the process demonstration was to achieve required performance and
quality with the most affordable manufacturing process.
