Kinks in flexible ducting must be avoided. 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 ...
A pressure filled jacket, rather than a simple extruded jacket, is preferable here. This fills all the gussets around the cores and ensures that the cores cannot untwist. The resulting dynamic cable is often stiffer than a standard cable, but lasts longer in applications where it must constantly flex.
Liquidtight flexible metal conduit (LFMC) is a metallic flexible conduit covered by a waterproof plastic coating. The interior is similar to FMC. The interior is similar to FMC. Flexible metallic tubing ( FMT ; North America ) is not the same as flexible metallic conduit (FMC) which is described in US National Electrical Code (NEC) Article 348.
In high temperature ducts, or ducts with wear potential, 2 + 1 ⁄ 2-inch refractory, is often anchored to the duct plate with V anchors at 6" O.C. (+/-) to resist a) temperature, or b) wear at elbows or a combination of these effects. Occasionally ceramic tiles or ceramic mortars are anchored to ductwork to resist temperature and wear.
Current research suggests that both energy and thermal performance can be improved in UFAD systems by ducting air to perimeter zones where loads tend to be the greatest. [16] Critics suggest however that such underfloor ducting reduces the benefit of having a low-pressure plenum space, as well as adding design and installation complications ...
