Cooling

Required Cooling & HVAC

What is it?

The system that removes heat generated by IT equipment.

Theoretical Definition

HVAC (Heating, Ventilation, Air Conditioning) systems maintain optimal temperature and humidity in data centers.

Why is it Important?

• Prevents overheating and hardware damage.
• Stabilizes environment for performance.
• Energy efficiency driver (cooling can consume ~40% of DC power).

How is it Planned?

• Hot aisle/cold aisle containment.
• Raised floor airflow or overhead ducts.
• Liquid cooling for dense racks.

Impact Down the Line

Poor cooling = outages, hardware failures. Overcooling = wasted energy costs.

Real World Example

Google pioneered liquid cooling for AI workloads (>10 kW per rack) to manage extreme heat.
