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 arent maintained, equipment could
fail and date center would experience costly
downtime. However, a proper cooling system will
allow data centers ot operate efficiently.

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.

Critical Cooling for Data Centers

• 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

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.

Critical Cooling for Data Centers

• Whats 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.
