A paper of RISE members published in “Cell Reports Physical Science” has received wide attention of scientific media (只有英文版本)

On 18 October 2023, the Prof. Shengwei Wang and two young members (Yinbo Zhang, the first author, and Hangxin Li) from the BEAR team in RISE and BEEE of PolyU published a research paper titled "The global energy impact of raising the space temperature for high-temperature data centres" in the journal ‘Cell Reports Physical Science’   After the online publication of this paper, it is immediately reported by many renowned scientific news outlets including EurekAlert, ScienceDaily, NewScientist, Techxplore, EurasiaReview, and Mirage News, etc. EurekAlert reported this paper as ‘How to build greener data centers? Scientists say crank up the heat’. Meanwhile, many other famous science news media also reprinted this report, such as, the website of the American Physicists' Organisation.   Cell Reports Physical Science, published by Cell Press, is a broad-scope, open-access journal that publishes high-quality and cutting-edge research across the spectrum of the physical sciences, including chemistry, physics, materials science, energy science, engineering, and related interdisciplinary work.   EurekAlert! is the world's largest, most authoritative and nonprofit news-release distribution platform covering all areas of science, medicine and technology, operated by the American Association for the Advancement of Science (AAAS). AAAS was the first permanent organization to promote science and engineering nationally and to represent the interests of American researchers from across all scientific fields. It is the world's largest general scientific society, with over 120,000 members, and is the publisher of the well-known scientific journal Science. Up to now, EurekAlert! has more than 14,000 registered reporters from more than 90 countries. More than 5,000 active public information officers from 2,300 universities, academic journals, government agencies, and medical centers are credentialed to provide new releases to reporters and the public through the system.   The original media report of EurekAlert! is attached below. How to build greener data centers? Scientists say crank up the heat  Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study, publishing October 10 in the journal Cell Reports Physical Science, proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.   “The cooling system accounts for over one-third of the data center’s total energy consumption, so many studies talk about reducing the energy consumption of cooling systems,” says senior author Shengwei Wang of the Hong Kong Polytechnic University. “But rather than finding better ways to cool the data centers, why not redesign the servers to operate at higher temperatures?”   Data centers typically operate at temperatures between 20–25°C (68–77°F) today. The conventional cooling systems that maintain these centers work by pulling computer-generated hot air past water-chilled coils to cool down the air before it cycles back to the space. The heated water then enters either chillers or a process called free-cooling before circulating back to the coils. Unlike energy-intensive chillers that operate similarly to air conditioners, free-cooling uses ambient air to cool the water with much less energy use.   To save energy, data centers are often built in colder areas to leverage free-cooling. But thanks to advances in electronic technology, engineers and scientists know that it’s no longer necessary to blast the chiller-based air conditioning at data centers. Many IT servers already allow a higher temperature operation above 30°C (86°F). This means that in most climates, including those that are hotter, data centers can also benefit from free-cooling by raising the temperature of data centers.“The question is, to what temperature?” says Wang.  To find out, Wang and his team built a model based on the conventional cooling system and simulated the system’s operation under different climate conditions. The results showed that data centers in almost all regions across climate zones could rely nearly 100% on free-cooling throughout the year when operated at 41°C, which they coined “global free-cooling temperature.” These data centers could save 13%–56% of energy compared to those that run at 22°C (71.6°F). Depending on an area’s temperature and humidity, the researchers say that data centers might not even need to raise the temperature that far to take full advantage of free-cooling. For example, the temperatures for Beijing, Kunming, and Hong Kong to entirely rely on free-cooling are 39°C (102.2°F), 38°C (100.4°F), and 40°C (104°F), respectively.   “But before we raise the temperature settings, we need to ensure three things,” says Wang. “First, we need to ensure the reliability of server operation. Second, the computational efficiency needs to remain the same. Third, we need to ensure the servers’ energy consumption is not increased by activating their built-in cooling protection, such as the fans.” That said, Wang is optimistic that it is possible for the next generation of servers to work at up to 40°C without performance degradation.   “For the first time we can provide cooling system engineers and server design engineers a concrete goal to work towards,” says Wang.“I think 41°C is achievable in the near future. We’re only 10°C (18°F) or less away.”   Paper link: EurekAlert report link: Links of other reports:
