1. Critical Cooling for Data Centers:
Evaluating Different Approaches

2. Critical Cooling for Data
Centers
Critical cooling for data centers is designed to maintain
specific humidity and temperature levels within
climate-sensitive environments.
If proper levels aren’t maintained, equipment could
fail and date center would experience costly
downtime.
However, a proper cooling system will allow data
centers ot operate efficiently.

3. Critical Cooling for Data
Centers
Air Cooling for Removing Heat
•Using air for critical cooling data centers provides
definite benefits.
•Computer room air conditioners (CRACs) remove heat
to the outside.
•Critical cooling for data centers commonly use a
raised floor approach.

Liquid Cooling for Heat Removal
•In many instances, liquid cooling provides more
targeted temperature control.
•This approach may be more efficient since the entire
room may not need to be cooled.
•However, significant downsides exist.
•Accidental water leaks
•Condensation build up
•More expensive than air cooling systems

5. Critical Cooling for Data
Centers
The Free Cooling Approach
•Free cooling reduces the amount of infrastructure
needed in critical cooling for data centers.
•It can refer to bringing in cooler outside air to cool
data center equipment.
•However, companies need to be cautious of
contaminants entering teh facility from the outside.
•Fortunately, many alternatives of this approach have
been developed to deal with the issues.

6. Critical Cooling for Data
Centers
What’s the Best Approach
•Critical cooling for data centers depends on several
factors including facility size, power, density, budget
and more.
•Several variations exist between air and liquid cooing
solutions.
•Finally, an industry group recently increased the
allowable temperatures for data center facilities.
