Green Data Center Cooling Techniques

Hot aisle/cold aisle containment

Hot aisle/cold aisle containment is a cooling technique that involves separating the hot and cold air streams in a data center. By creating a barrier between the hot aisle (where the servers exhaust hot air) and the cold aisle (where the cooling systems supply cold air), businesses can improve cooling efficiency. This technique helps to reduce the mixing of hot and cold air, minimizing energy wastage and improving overall cooling effectiveness.

Free cooling

Free cooling is a technique that utilizes naturally cool air, such as outdoor air or groundwater, to cool a data center. By using this external source of cool air instead of relying solely on mechanical cooling systems, businesses can significantly reduce energy consumption and lower operating costs. Free cooling is particularly effective in regions with favorable climate conditions and can be combined with other cooling techniques for optimal energy efficiency.

Liquid cooling

Liquid cooling is an alternative to traditional air cooling methods and involves the use of liquid cooling solutions to dissipate heat generated by servers. This technique has the potential to be more energy-efficient than air cooling, as liquids have a higher heat capacity and can transfer heat more effectively. Liquid cooling can be implemented in various ways, such as direct liquid cooling (placing liquid-cooled plates in contact with the servers) or immersion cooling (fully submerging servers in a cooling fluid).

Airside economization

Airside economization is a technique that involves using fresh outdoor air to cool a data center, rather than relying solely on mechanical cooling systems. By leveraging the external ambient air temperature, businesses can reduce the need for mechanical cooling and decrease energy consumption. Airside economization can be particularly effective in regions with cooler climates and can be combined with other cooling techniques for optimal energy efficiency.

Energy Management in Data Centers

Power usage effectiveness (PUE)

Power usage effectiveness (PUE) is a metric that measures the energy efficiency of a data center.
