Airside Economizers Use Free Air to Cool Data Centers and Reduce Energy Costs

摘要

Today's data centers not only require protection from the elements, but also need to save energy, as estimates indicate they consume about 1.5 percent of all power used in the US According to the Natural Resources Defense Council (NRDC), data centers are one of the largest and fastest growing consumers of electricity in the country. In 2013, 3 million computer rooms in the US used enough electricity to match the annual output of 34 large coal-fired power plants, and those statistics are expected to increase. Annual consumption is projected to increase by roughly 47 billion kilowatt-hours by 2020. As a result, the NRDC recommends the data center industry adopt best-practice efficiency behaviors as demand increases to unprecedented levels.
