Variable speed fans may not seem sexy to some folks. But saving money on data center energy bills is a beautiful thing, and cooling fan design is an area where small changes can generate big savings. Mark Fontecchio at SearchDataCenter reviews new approaches to fan design for computer room air conditioners (CRACs) and air handlers, which include:
Fans with no belts and pulleys, known as plug or plenum fans, or sometimes as "direct drive"fans.
Variable speed drive (VSD) fans that allow data center managers to reduce fan speed.
Variable frequency drive (VFD) that control motor speed.
Data center operators are also deploying fans in multiple locations to fine-tune air flow throughout the data center equipment. That includes the space under the raised floor, and in chillers and cooling towers. Read more at SearchDataCenter.
