and put it essentially in a closed space,
and then exhausted that heat directly out
of the building,” he recalls. “That kept
that heat from being spread throughout
the building and overheating everyone.”
BRING IN THE FANS
Once you’ve dealt with the major problems, the next step is to circulate the air
to equalize the temperature from floor to
ceiling. This is where fans come in.
But the answer might not be traditional
ceiling-mounted fans. Those may not
work over a mezzanine because safety
regulations might require a minimum
distance between the mezzanine floor and
an overhead fan.
That means companies may have to
get creative with their fan placement.
“Generally speaking, when we’re dealing
in mezzanines, we’re looking at either
mounting directional fans off a mezzanine blowing in, or mounting them
around the interior of the mezzanine,”
says Taber. A fan mounted to the side can
pull the hottest air from the ceiling level
and push it down toward the floor, creating a more uniform temperature from
floor to ceiling.
High-volume, low-speed (or HVLS)
fans are usually used to mix hot and cold
air, according to Dan Anderson, product
manager for Milwaukee, Wis.-based Rite-Hite Inc. Once the air is circulating, additional fans can be used to boost air speed
so occupants feel cooler. A high-volume,
high-speed (HVHS) fan is usually used
for that purpose.
As for fan positioning, some companies
place fans on tall posts on the lower floor,
which is more stable than a mezzanine,
and adjust them so that they blow across
the platform. An alternate approach is to
place fans at one side of the mezzanine
to blow air across and another series of
fans on the opposite side to pull air over
the platform, says Bradley A. Lehman,
regional sales manager for Wildeck Inc. in
Waukesha, Wis.
An automated fan-control system is
optimal. For one thing, says Taber, auto-
mated controls free up the workers to
focus on the task at hand. “For another,
you know it’s going to do the right thing,
rather than have user interaction muddle
things up,” he says. “We’ve seen fans
spinning in the wrong direction, or
off when they should be running to
help increase comfort. By using an
automated controller to take that
over … (you can help ensure) the
fans are going to run appropriately
whatever the conditions.”
WINTER WOES
Even in colder weather, heat can be
a problem. “A traditional heating
system might have a discharge air
temperature that’s 100, maybe 125,
degrees Fahrenheit,” Taber says.
That air will rise toward the ceiling,
with the result that, in a DC where
