Important results from the project
The project achieved its initial goals by demonstrating that a louver-based air control can reduce the rack PUE from 1.10 to 1.04. Measurements showed a net saving of energy on the fans in a rack without compromising thermal stability. The project also provided a simple, cost-effective prototype and methodology for future implementations.
Expected long term effects
Expected long-term impacts include widespread implementation of louver-based air control in edge nodes, which can lead to significant energy savings and lower operating costs. The solution contributes to reduced carbon emissions, extended server equipment lifespan, and a scalable methodology for sustainable cooling in future 6G environments.
Approach and implementation
The project was carried out as an empirical experiment in the RISE test lab with controlled server load and real-time measurement. A master´s student developed the prototype, which was manually regulated in the rack in conjunction with support of other softwares and scripts. Stress tests were performed on various server load, where ∆ρ, ∆T and power measurements were logged for 90 min per test. The schedule was followed according to plan, with only minor technical adjustments.
