CPD Courses

The data center industry is essentially a race for land and power, with scalability, efficiency and speed of deployment all key to success. Within this maelstrom of growth, the choice of cooling equipment within the data center building is a key consideration; Aisle containment or open aisle? Ceiling plenum or floor void? Equipment in a plant corridor or within the white space? High velocity air flow or low velocity? The decision often boils down to two choices: CRAH or fan wall? This short CPD course (approx. 45mins – 1 hour) explores data center design trends and offers a comprehensive comparison of the two technologies.

Topics covered:

• Industry trends
• Overview of Technology
• Architecture
• Comparison of each product
• System considerations

Global data use is exploding, with projected CAGRs of over 23%. The growth in data use / consumption, coupled with the emergence of new data-hungry applications like AI, means that data centers are getting more power-dense, bigger in size, hotter and more expensive to deploy. This lends itself to a cooling innovation shift, transitioning from air-cooling, to liquid cooling and a combination of the two.

Topics covered:

• The drivers influencing the shift to liquid cooling.
• A comparison of the various technologies looking to gain traction in the evolving market
• Direct to Chip – Single and Two Phase
• Immersion – Single and Two Phase

The question of which cooling technology will prevail and when is now largely over, as densities continue to rise and liquid cooling technology moves from theory to reality ever more quickly. The “one or the other” debate is also settled as it is clear that in many cases, air cooled systems will co-exist with liquid ones, supporting mixed density loads and dealing with heat rejection at both the chip and peripheral levels.

Topics covered:

• Some of the key considerations when it comes to designing and operating hybrid cooling architectures.
• Which technologies will be needed to support higher densities.
• Best practises when it comes to schematics, system temperatures and operational management for hybrid cooled data centers.

Most large data centres now operate using chilled water cooling. 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. As data centres get larger and the industry becomes globalised, one of the things we’re seeing is a move to variable primary-only chilled water systems. The challenge with these systems is the robust controls loop protocols to ensure the system delivers resilience and redundancy at the lowest possible energy output. Often a BMS is used to manage the system, but the level of built-in modification, control and protection of the system that we believe is required is not something that a BMS provider could achieve alone. This CPD introduces the idea and recommended specification of a dedicated real-time decision making tool. One that delivers the required cooling, maintains redundancy levels and increases resilience - all at the lowest possible energy outlay - while maintaining the system within the cooling equipment’s stated operating envelopes.
This course is aimed at anyone involved in specifying chilled water systems and associated controls in large data centres.

Topics covered include:

The trend towards variable primary rings and what they look like

The evolution of controls systems and the role of the BMS.

The requirement for an additional control system and what this should look like.

How CRAHs, chillers and the system as a whole should be programmed to behave.

Resilience and security implications.
