What is Adiabatic cooling?

Adiabatic cooling in a datacentre environment is referred to as ‘free air cooling’. The cooling process is a naturally occurring phenomena for regulating temperature and relies on a change in air pressure and volume expansion to reduce heat. When the pressure on a volume of air is reduced, the air expands and the volume increases. As it does so, energy (heat) within the air volume reduces and so does the heat.
