Description
G HVAC AIR DUCTWORK TECHNOLOGICAL FIELDThe present disclosure is concerned with HVAC (Heating, Ventilating and Air Conditioning) systems, and more particularly, with a modular air duct for HVAC systems and a method for its construction.
BACKGROUND ART Typically, a HVAC system is associated with ductwork air ducts (also referred to as air ducts, air conduits, duct pipes, air channels, trunks, air conduits etc.) coupleable to the air treating unit and configured for transferring blown treated air from the air treating unit to the desired one or more destinations. Such air ducts are mostly made of pipes at a wide variety of shapes and sizes and made of a variety of materials, e.g. metal (typically Aluminum), polymers, composite materials, etc. The main forms of air ducts are solid ducts, flex ducts (coiled/corrugated ducts), and inflatable sock ducts. It is appreciated that storage and transportation of such ducts requires considerable space and respective handling. Even more so, air delivery/supply openings should be carried out in such pipe ducts, hence requiring additional labor in performing such outlet openings. References considered to be relevant as background to the presently disclosed subject matter are listed below: - US2,039,886 - US2,147,7- US2,756,7- US9,291,2- US10,436,3- US2009309358 25
