ARLINGTON HEIGHTS, Ill., Oct. 1, 2020—The 2020 edition of Air Movement and Control Association (AMCA) International’s award-winning magazine, AMCA inmotion, is here.

The digital version is now available on the AMCA website, with the print version polybagged and set to mail with the October issue of ASHRAE Journal tomorrow.

Edited by AMCA Manager of Industry Content Scott Arnold and art-directed by Chicago-based freelance designer, illustrator, and photographer Bonnie James, the 2020 edition of AMCA inmotion includes the following articles:

  • UV-C for HVAC Air and Surface Disinfection” by Daniel Jones, UV Resources, and Michael Ivanovich, AMCA—For nearly a century, short-wave ultraviolet (UV) C (UV-C) energy has been used to destroy airborne and surface-bound microbes. Yet, despite decades of research and thousands of applications in hospital emergency and operating rooms, urgent-care centers, universities, and first-responder locations, UV-C has not been widely leveraged. The coronavirus disease 2019 (COVID-19) pandemic, however, is highlighting UV-C’s potential as an effective air and surface disinfectant. This article provides engineer-level guidance for the use of UV-C light to continuously reduce and even prevent the growth of dangerous microbes in HVAC systems and the circulation of infectious pathogens in air streams. (Includes full-page sidebar “Improving Upper-Room UV With Ceiling Fans” by David Rose, Big Ass Fans.)
  • Mitigating System Effect to Optimize Fan Performance and Efficiency” by Mike Humann, The New York Blower Co.—Fans used to move air in industrial and commercial applications are tested and rated in a laboratory under ideal conditions—that is, conditions designed to enable the equipment to achieve its maximum performance. As anyone who has set foot on a building site can attest, however, the conditions under which fans are put into service seldom are—and often are far from—ideal. The difference between how a fan performs installed in the field and how it performed when tested in a laboratory can be attributed to a phenomenon known as system effect. This article describes system effect, its causes, and its impact on fan performance. Additionally, it discusses strategies for minimizing, eliminating, or avoiding system effect to achieve optimal, reliable performance once a fan is installed.
  • Field Modifications of Fire, Smoke, and Combination Fire/Smoke Dampers” by James Carlin, Pottorff—In a perfect world, every construction project would run smoothly, with no oversights, delays, or other issues arising from unforeseen circumstances. This would include the installation of life-safety dampers, which, in the somewhat-less-than-perfect world we all inhabit, sometimes require modification in the field to be installed properly. This article discusses field modifications to fire-, smoke-, and combination fire/smoke-rated dampers typically covered in Underwriters Laboratories-approved installation instructions and options available when modifications fall outside of those instructions.
  • Straightening Out Fan Curves” by William “Bill” Howarth, Ventilation & Fan Consulting Service International LLC—Despite their complex appearance, fan curves—the graphical representation of a fan’s performance, specifically the relationship between the amount of airflow and the amount of static pressure produced—are fairly easy to interpret once one gains an understanding of the conventions and terminology used, enabling selection and specification of the best fan for an application.
  • Specifying High-Temperature Industrial Fans” by Aaron Saldanha, Howden—Whether it is optimizing the mix and temperature of a chemical composition in a petrochemical plant, regulating process conditions in a metal furnace, or simply circulating hot air through an industrial bakery oven, fans play a critical role in many manufacturing operations. It should come as no surprise, then, that failure of these fans can have dire consequences. This is especially true with high-temperature applications, given that, when a fan fails, the system typically needs to be shut down. The key to ensuring proper selection and construction of a fan for a high-temperature environment is good communication between the consulting engineer or end user and the manufacturer by way of the specification. This article discusses important considerations that go into the selection and construction of a fan for a high-temperature environment.

The 2020 edition of AMCA inmotion also includes updates from AMCA’s Asia (“China’s New Fan-Efficiency Standard: What to Expect” by Mdm SL Goh, Asia AMCA) and Middle East (“COVID-19 Calls Attention to Indoor-Air Quality” by Hassan Younes, ASHRAE Falcon Chapter) regions.
