Design elements - HVAC ductwork

The vector stencil library "HVAC ductwork" contains 63 duct and vent symbols. Use it for drawing HVAC system diagrams, heating, ventilation, air conditioning, refrigeration, automated building control, and environmental control design floor plans and equipment layouts. "Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. These needed airflows include, for example, supply air, return air, and exhaust air. Ducts also deliver, most commonly as part of the supply air, ventilation air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. A duct system is often called ductwork. Planning ('laying out'), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design." [Duct (HVAC).
