Adiabatic Cooling Explained

With climate change concerns becoming increasingly prevalent across the globe, technological engineers are continuously looking at new ways to enhance efficiency and minimise emissions. ‘Adiabatic cooling’ is the latest cutting edge concept to emerge and has the potential to slash the running costs of data centre air conditioning systems, as well as reduce impact on the natural environment. Want to know more about this technology of tomorrow? Read on for our guide to adiabatic cooling and how it is set to raise eco-friendly credentials and lower running costs of data centres.

What is adiabatic cooling?

Put simply, adiabatic cooling chills the air through changes in pressure which are caused by volume expansion. This is a natural phenomenon that occurs without the need for any external interference. Think about magma rising to the surface of a volcano, or wind flowing across the peaks of a mountain range. Both are examples of adiabatic cooling occurring in the natural environment. Now, the concept of ‘free cooling’ is being used to regulate temperature in some of the world’s biggest data centre hubs.

How does it work?

The system is used in evaporative coolers which suck in warm outside air through damp pads. As the warm air hits the pads the water begins to evaporate which pushes chilled air into the room. This essentially mimics the evaporative cooling process that occurs in the natural environment. Temperature can be regulated simply by adjusting the intensity of the air flow through the cooler.


Ease up on H20

One of the key benefits of adiabatic cooling is the fact that the process requires very little water, at least when compared with conventional cooling systems. In fact, experts estimate that the systems could save large data centres millions of litres a year. The reduced need for H20 also means that there is less polluted water released back into the environment.

Cut down on electricity

Adiabatic cooling units are extremely efficient and have the potential to cut electricity use by over 40%. If adiabatic cooling is adopted as a standard cooling solution the industry’s carbon emissions will plummet.

For data centres wanting to save cash and up their eco-friendly credentials, adiabatic cooling is a savvy air cooling solution. Whether used in small scale hubs or colossal complexes, data centre adiabatic cooling is set to be one of this year’s biggest developments.
