New South Wales is going in another.
However, there is little indication of a shift toward A2 or higher temperature ranges.Heat rejection systems, including mechanical cooling, have started to reach a plateau, with manufacturers making incremental enhancements to accommodate higher chilled water temperatures within the ASHRAE A1 range..
The next significant leap in the industry lies in the adoption of liquid cooling.Many larger data centre operators are now integrating liquid cooling solutions into their facilities.However, the lack of a standardised design topology for liquid cooling systems and their various configurations, poses a challenge.
We may witness the emergence of two distinct data centre topologies: the energy-efficient approach versus the high-density model, or perhaps a hybrid combination of both.These design choices will significantly impact heat rejection systems and other critical aspects, such as IT infrastructure development..
While the industry strives to reduce PUE in data centres, sustainability efforts should also focus on minimising process water consumption during adiabatic cooling.
Cooling towers, which consume substantial amounts of water year-round, may eventually be phased out or replaced with hybrid systems that prioritise dry cooling methods or utilise HDAC units.. By embracing these trends, data centres can enhance efficiency, reduce environmental impact, and pave the way for a more sustainable future in the ever-evolving landscape of IT infrastructure.. References.There were many reasons for this approach:.
Standard solutions allow for a greater level of design and refinement – if a solution is going to be used multiple times then the benefit of good design is multiplied and amplified.It afforded us a far greater level of stakeholder engagement and buy-in than we would typically achieve for a one-off design (see below).
This resulted in, for example, designs that were highly optimised in terms of layouts, space allocation, adjacencies and functional flows – which could then be deployed across the PETP programme and wider prison estate.It creates further efficiencies.
