Components of a VAV System
notes
Because variable-air-volume systems are installed in, and distribute air along
the surfaces of, ceilings, it is essential that the diffusers be compatible with the
ceiling design.
The T-bar ceiling is possibly the most popular design. It is constructed of a grid
of inverted T-shaped members suspended by wires from the floor or roof
structure above. Cross members added to the load bearing T-bars generate a
symmetrical ceiling pattern. Finally, ceiling tiles are laid in place and supported
by this grid.
