Ceiling-Mounted Spot Cooler
Keeps Server Room from Overheating
T
he University of Louisville
Health Care Outpatient
Center, in Louisville, Ky.,
had a problem with their server room
overheating. The 8-by-12-foot room
houses server and telecom equipment
that is vital to the center’s daily operations. The equipment runs 24 hours a
day, and must be kept cool at all times
to avoid malfunctioning, hardware
damage or system downtime.
The problem surfaced when, in an
energy-saving effort, the set points of
the building’s central HVAC system
were adjusted to turn the system off
at night. As a result, equipment in
the server room became excessively
hot and was shutting down at night,
incapacitating the health-care center
for hours at a time.
installation expense in penetrating the
roof and running refrigerant lines to
the outside unit, as well as running
electric lines to two separate pieces of
equipment. Also, the room was very
cramped, and there was really no space
to mount a wall unit.”
Dotson decided on a MovinCool
CM12 ceiling-mounted spot air
conditioner that offers a cooling
capacity of 10,500 Btu/h at 80 ºF
and 50% RH at the evaporator and
95 ºF and 40% RH at the condenser;
and 13,000 Btu/h at 95 ºF and 60%
RH. The self-contained unit, which
was supplied by Trane HVAC Parts
& Supplies, in Louisville, requires no
external refrigerant lines, outside condensing unit or charging of refrigerant, and measures only 15.5 in. high,
“The self-contained unit requires no external refrigerant lines, outside
condensing unit or charging of refrigerant, and fits easily into the space
above a drop ceiling. Built-in flanges and mounting brackets allow
quick installation with standard, off-the-shelf mounting hardware.”
The building’s facility manager knew
that continuing to run the central
air conditioning system to cool only
one room would be too costly, so he
contacted Joe Dotson, service account
manager of Scarborough Mechanical Services, Inc., the Louisville firm
that had installed the original HVAC
system, to propose a solution.
In evaluating the available choices,
Dotson excluded a precision cooling
system as having unneeded features
and an unnecessarily high price tag.
“In this situation, it would have been
overkill,” Dotson said. “A ductless
split system was another alternative,
but it would have meant additional
so it fits easily into the space above a
drop ceiling. Built-in 10-in. flanges
and mounting brackets allow quick installation with standard, off-the-shelf
mounting hardware. The unit plugs
into a 115-V electrical outlet, further
reducing installation costs.
“Installation was very straightforward,” Dotson said. “We got in and
out in a day, with no system downtime and minimal impact on the
customer. If the room had been unoccupied and we didn’t have to work
above all the computer equipment,
the installation would have probably
taken only half a day.
“One convenient feature of the
CM12 is that it has a built-in condensate pump, which eliminates an installation step or two. After attaching the
unit to the ceiling and connecting the
intake and exhaust ducts, we ran the

“A big advantage of a self-contained unit like the CM12 is that it’s
in an interior space where the heat load is fairly consistent throughout
the year, so we don’t have to worry about running an external condensing unit in low ambient conditions. We just set the thermostat
to one temperature and hold it there all year round.”
condensate drain to a sink in a nearby
maintenance closet.
“Then we installed the unit’s wallmount thermostat. The CM12 can
also be connected to a central control
system, but in this case there was
no need. A big advantage of a self-
contained unit like the CM12 is that
it’s in an interior space where the heat
load is fairly consistent throughout the
year, so we don’t have to worry about
running an external condensing unit
in low ambient conditions. We just set
the thermostat to one temperature and
hold it there all year round.”
Dotson is very pleased with the
results. “The health-care center has no
more shutdowns due to overheating,”
he said. “Also, the facility manager was
happy that we were able to perform
the installation so quickly and with no
interruption of the center’s operations.
He also likes the fact that without an
outside condensing unit, the system
has minimal maintenance costs.
“The CM12 is perfectly designed
for this type of application. It has the
usual MovinCool quality, it’s easy to
install in tight spaces, and it has an
affordable price tag.”
MovinCool’s CM12 ceiling-mount air conditioner features direct analog and digital
I/O, which are conveniently integrated with an energy management system (EMS).
