COMMENTARY
Industry on Display
The AHR Expo just gets bigger, and better. The Show in Chicago in January set records for net exhibit space, attendees and international exhibitors. But what numbers can’t show is the new products and rise of new technologies. Examples include Web-enabled smart equipment, solar-assisted equipment, geothermal technologies and new VRF products. Of course, energy efficiency is a god on the Show floor. As one attendee said, “Our customers are educated now, and energy efficiency is what they want.” This edition includes 15 pages of Show coverage, with stories on the international attendance, recaps of the news conferences, the product of the year, top trends and more. But the bulk of the coverage is products, sorted into categories. We’ve Fred Turner also created short links so you can get further information, or you can just click on these links in the digital version of ASHRAE Journal. I DON’T THINK ASHRAE Journal has ever published a photo of Laurel and Hardy, and I was a bit hesitant. But the photo from the movie The Music Box does help illustrate the concept of temperature lift. It also helps kick off an important monthly column on refrigeration by Andy Pearson, Ph.D., C.Eng. These short columns on concepts associated with refrigeration and heat pump systems are aimed at people who are not experts in refrigeration technology. “Hopefully, seasoned hands will find the series useful too, even if only to help explain a point to their less experienced colleagues,” says Pearson. THE ASHRAE Energy Awards were first presented in 1981. While the name has changed to ASHRAE Technology Awards, the purpose is the same. The award, said Charles F. Sepsy, ASHRAE’s president in 1981, “is part of a continuing effort to encourage and honor contributions by ASHRAE members in the area of energy conservation and to promote the dissemination of successful technologies.” Each winning project has been judged at chapter, region and international levels based on innovation, energy efficiency, indoor air quality, maintenance and operation, and environmental impact. Each includes at least one year of measured energy data. This year’s 25 winning projects are featured in this edition. Case studies on almost all of the projects will be published in 2012 in ASHRAE Journal or High Performing Buildings magazine. These start in this edition with the cover article on a CO2 ice rink. This is one of very few CO2 systems in North America and the world’s first ice rink with a system that uses CO2 as both the primary and secondary fluid. WE ALSO HAVE a strong lineup of columns and articles that are too many to mention. Of particular note are the articles by Steve Taylor, P.E., Fellow ASHRAE, and John Murphy. Also, Joe is back with another good read, eh. I speak for all the staff when I say we’re proud of this issue. We hope you like it.
