SYSTEM PACKAGE
Basic market needs for current
data
center
designs
are
addressed through SEMCO’s
simple approach. This system,
designed specifically for data
centers,
incorporates
few
components with an easy to
maintain and logical hydronic
coil system achieving a typical
annual Power Usage Efficiency
(PUE) of 1.122 (based on
Washington DC area conditions).

Outside Air
The diagram above shows the basic piping arrangement between the two airstreams. Designed to handle a range
of temperature differentials, this high-efficiency system not only rejects heat for the data center, but also starts to
economize at an outdoor ambient temperature within 10 degrees of the desired process side leaving air temperature! This
is 20-30 degrees warmer (sooner) than other air-to-air competitive options.

SYSTEM FEATURES & OPTIONS:
•
Prepackaged with controls (providing stand-alone water cooled central plant and air handler hybrid)
•
Evaporative cooling (available option, but not required for superior PUE compared to all other conditioning systems)
•
Shipped in single piece; reduced number of lifts speeds final build
DATA CENTER
PUMP AND REFRIGERATION SYSTEM
The key technology to lower PUE
and low power input is the use of EC
components (fans and pumps); however,
the secret is the simple pumping design
and screw chiller technology.
The run-around system incorporates
high capacity coils and a pump
configuration that understands load
management under all conditions.
When ambient temperatures are too
high and do not create the necessary
leaving water temperature, only then
does the chiller operate to provide
supplemental cooling to achieve leaving water and
process air temperatures.
In the event that the scavenger supply water is warmer
than the process return, the system will transfer into
a more traditional dry cooled chiller configuration to
prevent overburdening the chiller with its own heat. It
should be noted that this only occurs during the few
hours when the outdoor ambient temperature is greater
than 90 degrees.
When the outside air has cooler or cold conditions, the
scavenger fans reduce in speed to further save energy.
The pumps continue to run as air friction is more
detrimental than fluid friction.
PANEL SOLUTIONS FOR SUPERIOR PLENUMS
Key benefits of using modular duct systems include:
Data centers are actually large air handling
units. The load is placed within this “air
handler” and forced air is passed to
dissipate heat. SEMCO’s AT-PANL Solutions
provide acoustic-thermal plenum systems
that are designed to distribute air efficiently,
effectively and quietly.
•
COST EFFECTIVE: Various panel constructions and thicknesses
allow us to customize your project and eliminate costly overkill.
The need to “stick build” walls and plenums is eliminated.
•
EASY INSTALLATION: Roll formed tongue-and-groove construction
with a fully enclosed and insulated joint allows for faster installation
and a better fit with closer tolerance.
•
FIRE RATED & CUSTOM OPTIONS: Fire rating, various metal types,
powder coating and finishes are available to customize the system.
