HVAC ductwork - Vector stencils library

The vector stencils library "HVAC ductwork" contains 55 duct and vent symbols of HVAC mechanical components. Use it for drawing HVAC ductwork system diagrams, heating, ventilation, air conditioning, refrigeration, automated building control, and environmental control design in the ConceptDraw PRO diagramming and vector drawing software extended with the HVAC Plans solution from the Building Plans area of ConceptDraw Solution Park.

Design elements - HVAC ductwork

The vector stencils library "HVAC ductwork" contains 55 ducts, vents and HVAC mechanical components symbols.
Use the design elements library "HVAC ductwork" for drawing the HVAC ductwork system diagrams, heating, ventilation, air conditioning, refrigeration, automated building control and environmental control system layout floor plans.
"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). Wikipedia]
