Design elements - Registers, drills and diffusers

The vector stencils library Registers, drills and diffusers contains 47 symbols of rectangular, circular, linear and troffer air handling inlet/ outlet components.
Use the design elements library Registers, drills and diffusers to draw reflected ceiling plans (RCP) and HVAC layout floor plans using the ConceptDraw PRO diagramming and vector drawing software.
"A ceiling is an overhead interior surface that covers the upper limit of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the floor or roof structure above.
Ceilings are classified according to their appearance or construction. A cathedral ceiling is any tall ceiling area similar to those in a church. A dropped ceiling is one in which the finished surface is constructed anywhere from a few inches to several feet below the structure above it. This may be done for aesthetic purposes, such as achieving a desirable ceiling height; or practical purposes such as providing a space for HVAC or piping. An inverse of this would be a raised floor. A concave or barrel shaped ceiling is curved or rounded, usually for visual or acoustical value, while a coffered ceiling is divided into a grid of recessed square or octagonal panels, also called a "lacunar ceiling". A cove ceiling uses a curved plaster transition between wall and ceiling; it is named for cove molding, a molding with a concave curve." [Ceiling. Wikipedia]
"... reflected Ceiling Plans (RCP)s showing ceiling layouts appear after the floor plans." [Plan (drawing). Wikipedia]
The shapes library "Registers, drills and diffusers" is contained in the Reflected Ceiling Plans solution from the Building Plans area of ConceptDraw Solution Park.

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]
The shapes library "HVAC ductwork" is included in the HVAC Plans solution from the Building Plans area of ConceptDraw Solution Park.
