ductwithin
Ductwithin is a term used in HVAC engineering to describe an arrangement where air ducts are embedded or nested within other structural elements or duct systems. In practice, this can refer to a duct placed inside another duct (a coaxial or nested configuration) or an air duct that runs within walls, slabs, or other concealed cavities. The concept aims to optimize space, conceal visible ductwork, or improve thermal and acoustic performance in mechanical design.
Variants of ductwithin include coaxial duct systems, where an inner duct carries supply air inside an outer
Design considerations for ductwithin emphasize clearance, accessibility, and fire- and moisture-stopping requirements. Proper insulation and airtight
Applications of ductwithin are most common in commercial buildings, hospitals, and dense urban developments where space
