Information @ a Glance

  • A duct(HVAC) refer to transfer of air between spaces in a building.
  • HVAC is an initialism or acronym that stands for "heating, ventilating, and air conditioning".
  • Heating, ventilating, and air conditioning is based on the basic principles of thermodynamics, fluid mechanics, and heat transfer.
  • The three functions of heating, ventilating, and air-conditioning are closely interrelated.
  • All seek to provide thermal comfort, acceptable indoor air quality, and reasonable installation, operation, and maintenance costs.
  • HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces.
  • Flex duct is one of the most used  and feared materials in the HVAC field. It is irreplaceable in making short connections from sheet metal duct to grilles and registers.
  • Spiral 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.
  • The 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.
  • The 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.
  • The 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.
  • The advanced-design duct features a foreshortened, compact geometry with low inlet loss.
  • A 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.
  • Extractor fans and ducting are generally the answer providing the means to mechanically remove moisture and fume laden air to the outside.
  • By using ducting components a cooker hood or extractor fan may be positioned conveniently and not always directly on an outside wall giving more freedom to position appliances in the kitchen, bathroom and utility room.
