Why Data Center Cooling Is Different
Cooling accounts for roughly 40% of a data center’s energy consumption. Unlike standard commercial HVAC, data center cooling systems operate 24/7/365 with zero tolerance for downtime. CRAC/CRAH units, chilled water systems, economizers, and liquid cooling all require contractors with specialized knowledge.
Types of Data Center Cooling Systems
- CRAC/CRAH units — Computer Room Air Conditioning and Air Handling units
- Chilled water systems — central plant cooling distributed to CRAHs
- Economizers / Free cooling — leveraging outside air or water-side economization
- In-row and overhead cooling — targeted cooling for high-density deployments
- Liquid cooling — direct-to-chip and immersion cooling for AI/GPU workloads
