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."

New-Old Refrigerant: Carbon Dioxide for Industrial Refrigeration

ASHRAE Journal, Aug. 2016, by Donald L. Fenton.

"CO2 is one of the five natural refrigerants and over the past 20 years has gained popularity, particularly with low-temperature refrigeration for industrial systems."

Chiller Plant Optimization Yields $386,000 Utility Rebate

Chiller & Cooling Best Practices, Aug. 2016, by Mike Flaherty.

"As a result of the project, this manufacturing site is saving approximately 4,450,000 kWh on 19,000,000 ton-hours of annual cooling production. This tremendous efficiency gain equates to $425,000 in energy annual savings and earned the site a $386,000 PECO utility rebate. The site’s chillers are now sequenced based on efficiency.  All pumps are variable speed and they are sequenced to meet the flow demand at the lowest total pumping energy. Consequently, the system pressure has been reduced from over 100 PSI to approximately 78 PSI."

Package Boilers Find New Friends

Plant Engineering, Jul/Aug 2016.
http://www.plantengineering.com/single-article/package-boilers-find-new-friends/6dff20bf020db5486b2b87a3b6963077.html

"For original equipment or replacements, package boilers offer efficiency, redundancy, flexibility: Advanced controls manage steam ramp-up and ramp-down for better combustion efficiency and heat transfer; improvements create efficiencies as high as 85%."

CHP a ‘Powerful Combination’ For Plants

Plant Engineering, Jul/Aug 2016, by Roy Palk.

"The pressure is on for industrial plants to become radically more energy efficient. The ongoing renaissance in combined heat and power (CHP), also known as cogeneration, is a major reason why."

Industrial Hydronic System Manual-Balancing Methods

Chiller & Cooling Best Practices, Aug. 2016, by Brandon Aitken.

"Hydronic balancing in industrial heating and cooling systems is an often overlooked final step in startup and commissioning of new and modified hydronic systems.  Insisting on a complete system balance upon startup of a new or modified system is an inexpensive insurance policy for any design engineer or installation contractor to protect their reputation against a system that is not performing to design conditions.  There are several methods of hydronic system balancing utilized in commercial and hospitality buildings, however, they are rarely found in the manufacturing and industrial environments."

Sparks Dynamics Optimizes NIST Compressed Air System

Compressed Air Best Practices, Aug. 2016, by Mac Mottley.
http://www.airbestpractices.com/technology/compressor-controls/sparks-dynamics-optimizes-nist-compressed-air-system

"Sparks Dynamics, a leading cloud based remote monitoring and data analytics technology company, entered into a Cooperative Research and Development Agreement (CRADA) with NIST researchers to develop industrial compressed air pattern analysis to enhance system efficiency and reliability."

The Importance of Bi-directional Compressed Air Flow Measurement

Compressed Air Best Practices, Aug. 2016, by Pascal van Putten.
http://www.airbestpractices.com/technology/instrumentation/importance-bi-directional-compressed-air-flow-measurement

"Technology is available which enables a compressed air flow meter to measure not only the magnitude of the flow, but also the direction. Why is this important? In this article we will describe two case studies where bi-directional compressed air flow measurement plays a key role to come to the right conclusions."

Innovations in Motor Technology Spark Energy Efficiency

Business Energy, Jul/Aug 2016, by Patrick J. Piper.
http://foresternetwork.com/business-energy-magazine/be-energy/be-energy-efficiency/innovations-in-motor-technology-spark-energy-efficiency/

"With minimum efficiency regulations increasing two to three times every decade, the engineering preference to make motors more efficient is coming to the fore. Motor manufacturers have been trying to improve the efficiency of their motors for years, however there hasn’t been a new technology to rival ECM motors in efficiency and performance."

Regulation of Commercial Fan Efficiency: An In-depth Exploration of the Department of Energy’s Fan and Blower Rule

Business Energy, Jul/Aug 2016, by Trinity Persful.
http://foresternetwork.com/business-energy-magazine/be-energy/be-energy-efficiency/regulation-of-commercial-fan-efficiency/

"Fans consume 14% of the electricity purchased by industrial and commercial buildings. Yet, fan efficiency has escaped the attention of those who design efficiency into the air systems they specify. That is about to change. The US Department of Energy (DOE) will publish their proposed rule this year covering fans from 1 to 200 horsepower. This new regulation will determine compliance at the design point of the fan."
