VAV diffusers are available in two basic types: mechanical (thermal) and digital (electric). In this post, we take a closer look at the mechanical version, which requires no electrical or pneumatic connections and is powered by the temperature of the air.

Not only does the positive buoyancy of the supply air work against the air distribution system, but most overhead mixing systems are designed with low supply air volumes (relative to cooling) and high supply air temperatures (more than 15°F above room temperature).

This is in contrast to turbulent flows, where chaotic changes in pressure and velocity can be observed as vortices, or eddies (reverse swirling currents), and where much more mixing occurs within the fluid.
