Data Centre applications
“Data centres account for 2% of global electricity usage”
International Energy Agency, 2022
“Reducing fan speeds by 20% can save up to 50% in energy costs”
Along with managing heat, cooling systems also maintain correct levels of humidity. This preventing build-up of static electricity and condensation, which can both lead to equipment failure.
Optidrive variable frequency drives provide precise and efficient control of fans, pumps and compressors, the components which are at the heart of most cooling systems. Optidrive VFDs help to deliver highly reliable performance in cooling systems, whilst the energy cost savings they deliver can deliver payback on the VFD cost in months rather than years.
Air-Based Cooling
Computer Room Air Conditioning (CRAC) Units
These work like conventional air conditioners, using refrigerants and compressors to cool the air, which is then distributed through raised floors or overhead ducts.
Computer Room Air Handlers (CRAH) Units
These rely on chilled water supplied by external chillers and use fans to distribute cold air.
Hot Aisle / Cold Aisle Containment
This involves arranging server racks to separate hot exhaust air from cold intake air, improving efficiency.
Direct and Indirect Evaporative Cooling
Uses evaporation to cool air before it enters the data centre, reducing reliance on mechanical refrigeration.
Liquid-Based Cooling
Chilled Water Systems
Use water-cooled chillers and cooling towers to dissipate heat from the data centre environment.
Direct-to-Chip Liquid Cooling
Delivers coolant directly to server components, providing more efficient heat dissipation.
Immersion Cooling
Submerges servers in non-conductive liquid, which absorbs and dissipates heat effectively.
Free Cooling
Air-Side Economisers
Use outside air when ambient temperatures are cool enough to reduce the need for mechanical cooling.
Water-Side Economisers
Use cool water sources, such as rivers or lakes, or take advantage of low outdoor temperatures to reduce chiller use.
