"Evaluating fans and fan systems and their impact on operating costs."

New NSF Industry/University Cooperative Research Center Led by WPI Aims to Dramatically Reduce Energy and Water Use by Improving Industrial Drying

Worcester Polytechnic Institute News, Oct. 4, 2016.
https://www.wpi.edu/news/new-nsf-industryuniversity-cooperative-research-center-led-wpi-aims-dramatically-reduce-energy

"Funded by the National Science Foundation, the new center will attack one of the most energy-intensive processes [industrial drying] in manufacturing; its research could help save 200 trillion BTUs of energy in United States each year."

The Advantages of Onsite Nitrogen Generation for Brewers

Compressed Air Best Practices, Oct. 2016, by Mike Robinson.

"Although the basic principles behind brewing are little changed since their advent, the technological aspects are much improved. Today, large stainless steel tanks are used for fermentation and wort aeration, and complex, automated systems help with everything from temperature regulation to bottling. A price tag comes with these high-tech systems, and it’s not insignificant. By using onsite nitrogen generation, brewers can save significant amounts of money throughout the life of their operation."

New CSA C837-16 [Canadian] Compressed Air Efficiency Standard

Compressed Air Best Practices, Oct. 2016.

"After almost three and a half years of development work the Canadian Standards Association C837-16 document “Monitoring and Energy Performance of Compressed Air Systems” has finally been published and is available for download."

Energy Management Considerations With Today’s Drive Systems

Compressed Air Best Practices, Oct. 2016, by Michael Perlman.

"It is a fact that most of the energy loss in a system occurs in three areas, namely, the generation, distribution and conversion of energy into useful work, the last being accomplished through heat exchangers, pumps, motors and drives.  This paper will concentrate on the last product group."

Innovations for Improved Gas Turbine Productivity

Power Engineering, Sept. 2016, by Gerrill Griffith.
http://www.power-eng.com/articles/print/volume-120/issue-9/features/innovations-for-improved-gas-turbine-productivity.html

"... Now, with demands for energy rising along with calls for reduced greenhouse gas emissions, the need for cleaner more efficient next generation turbine technology is critical. With a robust research portfolio, productive partnerships, and a mandate to increase power-producing efficiencies and improve the environment for future generations, the National Energy Technology Laboratory (NETL) is shepherding innovations for improved gas turbine productivity."

Designing With Liquid-Immersion Cooling Systems

Consulting-Specifying Engineer, Sept. 21, 2016, by Saahil Tumber.

"Liquid cooling refers to a scenario where liquid (or coolant) must be supplied to the ITE. An IT cabinet is considered to be liquid-cooled if liquid, such as water, dielectric fluid, mineral oil, or refrigerant, is circulated to and from the cabinet or cabinet-mounted equipment for cooling. Several configurations are possible, depending on the boundary being considered (i.e., external or internal to the cabinet). For the same heat-transfer rate, the flow rate requirement for a liquid and the energy consumed by the pump are typically much lower than the flow rate requirement for air and the energy consumed by the fan system. This is primarily because the specific volume of a liquid is significantly lower than that of air."

This is One of the Most Efficient Energy Sources Out There. So What’s Holding it Back? [Cogeneration]

Alberta Oil, Sept. 9, 2016, by Nick Wilson.
http://www.albertaoilmagazine.com/2016/09/cogeneration-one-efficient-energy-sources-whats-holding-back/

"Combined heat and power generation, or “cogeneration,” is clean power’s unsung hero. And the oil sands are its ground zero, supplying about 50 percent of Alberta’s 4,821 megawatts of electrical capacity, and pushing the province to the top of Canada’s “cogen” table. It’s not just ultra-efficient; it can be lucrative too. Oil sands operators have earned as much as $2.43 per barrel from power sales to the electricity grid."

How Do You Size a VFD?

Flow Control, Sept. 2016, by Jeff Bergman and Sean Fitzpatrick.
http://www.flowcontrolnetwork.com/how-you-size-vfd

"Confusion often surrounds the proper sizing of variable frequency drives (VFDs), and sometimes, knowing when and how to choose one may be difficult. Actually understanding what a VFD does might make this decision easier and the requirements less difficult to understand."

Tapping In to the Cost-Saving Power of VFDs

Business Energy, Sept/Oct. 2016, by Dan Rafter.
http://foresternetwork.com/business-energy-magazine/be-energy/be-energy-management/apping-in-to-the-cost-saving-power-of-vfds/

"What kind of difference can a variable frequency drive—better known as a VFD—make for a municipality? A significant one. Just look at the town of Mooresville in North Carolina, where a VFD developed by Eaton has not only boosted the energy efficiency of the municipal water treatment plant, but has also extended the life expectancy of a pair of new 800-horsepower pumps at the facility."
