  2. Duct (flow) - Wikipedia

    en.wikipedia.org/wiki/Duct_(flow)

    Some flexible duct markets prefer to avoid using flexible duct on the return air portions of HVAC systems, however flexible duct can tolerate moderate negative pressures. The UL181 test requires a negative pressure of 200 Pa. To use flexible ducting in a system, make sure to pull the duct tight so you get the full internal diameter.

  3. Ductwork airtightness - Wikipedia

    en.wikipedia.org/wiki/Ductwork_airtightness

    So-called "duct tapes" are often not suited for sealing ducts, [17] [18] which explains why, in the US, the International Energy Conservation Code (IECC) requires any tape used on duct board or flexible ducts to be labeled in accordance with UL 181A or 181B. Typical reasons for poor ductwork air tightness include: [19] [20] [12]

    en.wikipedia.org/wiki/Underfloor_air_distribution

    Underfloor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of a HVAC system. UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air to supply outlets (usually floor ...

    Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. [32] (Minisplit ...

  7. Duct leakage testing - Wikipedia

    en.wikipedia.org/wiki/Duct_leakage_testing

    Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
