A multiple stage approach to mitigate the risks of telecommunication equipment under free air cooling conditions
چکیده انگلیسی

The telecommunication industry is concerned about the energy costs of its operating infrastructure and the associated greenhouse gas emissions. At present, more than half of the total energy consumption of data centers is devoted to the power and cooling infrastructure that supports electronic equipment. One method of reducing energy consumption is an approach called “free air cooling,” where ambient air is used to cool the equipment directly, thereby reducing the energy consumed in cooling and conditioning the air. For example, Intel demonstrated free air cooling in a 10-megawatt (MW) data center, showing a reduction in energy use and savings of US$2.87 million annually. However, the impacts of this approach on the performance and reliability of telecommunication equipment need to be identified. The implementation of free air cooling changes the operating environment, including temperature and humidity, which may have a significant impact on the performance and reliability of telecom equipment. This paper discusses the challenges posed by free air cooling and presents a multi-stage process for evaluating and mitigating the potential risks arising from this new operating environment.


► Analyze the challenges posed by free air cooling (FAC).
► Present a multi-stage process to mitigate the risks of FAC.
► Propose a prognostics-based method to mitigate risks in data centers in operation.
► Present a case study to show the prognostics-based method implementation.
