Air Ducting are passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducting also delivers ventilation air as part of the supply air. As such, air ducting is one method of ensuring acceptable indoor air quality as well as thermal comfort.
