Most large data centres now operate using chilled water cooling, with chillers supplying water to data centre cooling units, usually computer room air handlers, that take heat from the servers and return it to the chillers where the heat is rejected to air and the process starts again.

Much of the improvement focus over the past decade has been on the equipment itself, but the chilled water system as a whole is now under the spotlight.
