You Need To Start With The Right Kind Of Cooling
Why Comfort Air Conditioning
Should Make You Uncomfortable
Standard building air conditioning is designed for
one thing: to keep people comfortable. In most
cases, this is done 8-12 hours each day, five days a
week and only during the warmest months. These
units are simply not built to handle the 24 hour-a-
day operation associated with computer rooms and
communications facilities.
The Protection Never Stops
Mission-critical cooling systems are designed to run
the same hours as your network — continuously, year
in and year out, around the clock. These systems are
specifically designed to maintain both temperature
and humidity levels to equipment manufacturers’
specifications, which are several times more
stringent than those designed for the human body.
Some operations may be tempted to utilize standard comfort cooling systems to save money or to avoid using additional floorspace
within their facility. But while these moves may provide some benefits in the short term — they must be balanced against the
cost of potential downtime and equipment damage caused by serious overheating, as well as the risk of financial loss.
Removing Heat Without Removing
The Humidity
The biggest problem with ordinary air conditioning
systems is they are designed for the comfort of
people — not the protection of computer-based
electronic systems. Unlike people, computers
generate dry (also called sensible) heat, but
not humidity.
With a large percentage of their total capacity
devoted to the removal of moisture, comfort systems
can lower room humidity far below acceptable
standards for electronic equipment — and they have
no provisions for adding moisture. To correct this
situation, precision air conditioning systems typically
have a high ratio of sensible-to-total cooling capacity
to remove heat from the air. This allows for much
lower operating costs since the type of cooling is
matched to the load. These units also use integrated
humidification systems to provide the necessary level
of moisture control.
Using rigid, overhead ducts
provides insufficient air volume
(350-400 CFM/Ton) which
results in hot spots. They are
also difficult to relocate.
Minimal air filtration
is typically provided
with comfort systems.
Using separate humidification
systems, not controlled by
the cooling system, can
waste energy and reduce the
stability of the environment.
Comfort systems can over-dry
room air because of their
lower Sensible Heat Ratio.
They typically do not provide
integral humidity control.
