Seeing the Invisible

By creating a computer model of the data center our engineers are able to see the invisible. Power, cooling air, hot exhaust air etc… The model then allows for real-time changes to determine the best way for cooling efficiency.

What Kind of Changes?

There are numerous tools to adjust the flow of data center air. Placement of perforated tiles/grills or their percentage of flow. Filling in of cable cut out covers or other unnecessary openings in the raised floor. Adjusting the pressure in the subfloor so as to increase airflow to the intake of the computers. Partitions that separate hot and cold air. Proper placement of computer equipment and racks. Placement of Computer Room Air Conditioners. And numerous other devices.

Case Study One – Subfloor Pressure

The foundation of every data center cooling solution is the subfloor air plenum. Excessive velocity in the subfloor caused by high volume airflow from the CRAC units creates ‘rivers’ and ‘eddies’ in the subfloor plenum.

See the Velocity Adjustor

Case Study Two – Bypass Airflow

Air coming from the subfloor plenum through an unmanaged opening (cable cutouts, unsealed penetrations) will negatively impact your data center in two ways:

• Decreases subfloor air pressure
• Latent cooling penalty

SubZero Cube's are a custom cable cutout cover that completely seal cable penetrations in the floor.

• Can be made to any size
• Don’t leak like brush based units
• Completely non-flammable

Case Study Three – RackHat Ceiling Partition System

Hot spots are becoming more and more of a problem in today’s data centers. Often these hot spots are caused by the re-circulation of hot exhaust air from the equipment in the racks.

Complete separation of hot and cold air must be achieved in order to stop re-circulation and prevent data center hot spots.
