Data Center Costs as a Driving Force for Energy Efficiency: Part 2

In the first part of this two part series, I outlined why computing power has steadily increased over the years and which challenge it inherently brought for today and in the future. In Part 2, I address why the question of the appropriate cooling system and how additional savings through intelligent waste heat utilization is possible as well as why there are still reservations to water cooling to reduce energy requirements.

Status quo in the air conditioning of data centers is cooling by mechanically cold air.

The entire room is cooled, but more than half of the cold air does not reach the heat hotspots, like the CPU. In doing so, huge sums of money are literally blown into thin air. One of the alternatives to air cooling is to use methods with water or other liquids. But as soon as the data center industry is confronted with "water," it frightens them immediately. Water and IT equipment – they do not fit together. Nevertheless, there are a few operators already who rely on the alternative cooling medium.
