Energy Efficient Data Centre Design
Traditional Cold/Hot Aisle Arrangement
Not all cold air from the floor
grill enters the server rack. A
large portion returns to PAC
unit. Not all capacity is used
and PAC unit has to be
oversized.

As heat load increases,
airflow requirements
increase and rack draws air

Problems With Conventional Cooling
Airflow distribution in a
Data Centre is difficult to
predict.
Cool air often bypasses
the server racks and
passes straight back to
the PAC units.
Hot air discharged by
the racks is drawn back
into the racks before
being cooled.
PAC units have to supply
more cool air than
should be needed to
compensate for the
inefficiency.
About Conventional Cooling
“ 72% of cool air generated by precision air conditioning
units does not pass through IT equipment but short
cycles back to the PAC unit.”
“ 2.6 times more cooling is delivered than is required by
the IT equipment load.”

3. Heat Containment System (The
CITEC Solution)
35 - 40OC /16 – 23%RH
Intelligent fan monitors
pressure, temperature &
humidity to ensure the rack is
kept at the correct
temperature. Back-up fan
blades are built in for additional
security.

Heat Containment Rack
(CITEC Solution)
Traditional Rack
Perforated panel
restricts airflow,
pressure must build up
inside the rack to enable
air flow.
Fan draws hot air out of
the rack. Ensure hot air
is extracted effectively.
Some hot air is drawn
back to the front due to
lower pressure.
Backing plate ensures
only cold air is drawn
through equipment .

Benefits of Heat Containment (The CITEC
Solution)
No hot aisle, the whole data centre is
cold.
No circulating hot air.
Consistent temperature from bottom of
the server rack to top.
Increased PAC Unit efficiency.
Precise control over temperature of air
delivered to server racks.
Allow higher capacity with lower airflow.
