CPI's Thermal Design Manager, Travis North, Contributes to Green Grid White Paper on Cooling Systems

August 19, 2011

Justifying return on investment (ROI) is often times one of the biggest challenges faced by data center managers working to implement new and upgraded solutions - especially when it comes to more innovative methods of thermal management and data center cooling. 

In a recently released white paper prepared by the Green Grid, entitled "Case Study: The ROI of Cooling System Energy Efficiency Upgrades," Chatsworth Products, Inc. (CPI) Thermal Design Manager, Travis North, joins a collection of industry-wide experts to independently investigate the ROI for various non-contained system upgrades while evaluating the Power Usage Effectiveness (PUE) per upgrade.

In this comprehensive, year-long study, every piece of a Green Grid member company's (MC) data center cooling infrastructure was evaluated, including cabinet selection, room air handlers, external chiller plant performance and the measured results of all actual energy savings.

In-depth analysis includes how the MC's external ambient temperature had a significant impact on the efficiency of the cooling system, how cooling energy consumption varied throughout a given day, how control significantly impacted CRAH performance, and the difficulty in properly matching a room's CRAH to its pre-designated zones.

Ultimately, the MC was able to reduce all working CRAH fans from maximum speed to minimum by verifying cooling load performance, thus saving the customer over 300kW or 10% of their daily total energy consumption.

As an excellent resource for those wishing to justify ROI on similar projects, we encourage you to take a moment and read this valuable white paper in full. Jeff Cihocki, eContent Specialist
