A new data center cooling solution could give the Kyoto heat wheel a run for its money.
APC by Schneider Electric just announced the EcoBreeze, an evaporative and air-to-air heat exchange cooling solution, which has the ability to switch between air-to-air and indirect evaporative heat exchange, or inside mechanical refrigeration. Bob McFarlane, Principal, Shen Milsom & Wilke, mentions that this automatic switching between the two cooling techniques is a breakthrough.
“Designing the control systems to switch between, or to integrate, these two very different systems has been one of the most challenging aspects of air-side free cooling designs,” said McFarlane.
The Kyoto wheel, notes McFarlane, balances separating outside and inside air with accomplishing efficient heat exchange, with a low outside-to-inside transfer, but isn’t designed to effectively integrate/switch between evaporative and air-to-air – it still needs control systems for the mechanical cooling plant. Enter EcoBreeze.
“This new APC device combines a built-in cooling compressor of the highest available efficiency with a unique air-to-air heat exchanger using evaporative cooling into a total, self-contained package that also incorporates all the necessary control systems and totally separates outside from inside air,” said McFarlane. “It would appear to be a well thought-out solution to the air-side free cooling challenge.”
Because of this “all-in-one” solutions approach, McFarlane says that EcoBreeze could be a serious contender pitted against the Kyoto wheel, depending on its cost.
APC’s EcoBreeze is available modularly, in 50 kw units that can be grouped up to four or eight modules. The product will be available next year, and you can view full specs in the original press release.
