DuctSox has introduced the OvalSox™, fabric duct designed for low clearance HVAC ventilation in industrial and commercial building applications. OvalSox, which ranges from 11 to 22 in high and 47 to 93 in wide, saves 13 to 27 in of head room versus round HVAC fabric and metal duct alternatives, according to the company. Officials also claim there is no air volume or air dispersion lost with OvalSox versus conventional duct that hangs too low and obstructs industrial overhead conveyors or high rising equipment. OvalSox is also ideal for datacenters with high rising security cages or low hung ceilings in offices and other commercial designs.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
