It’s been seven years since the AHR Expo last visited Dallas.
Attendees and exhibitors will get a chance to see how the city and HVAC market has changed since then when the show arrives Jan. 29-31.
“This enthusiastic response from previous exhibitors and active interest from new companies supports the fact that AHR Expo is indeed the HVACR industry’s leading world event,” said Clay Stevens, exposition company president.
One change attendees or exhibitors at the 2007 show may notice is an increased focus on environmental or “green” building. It reflects the interests of today’s industry professionals, organizers said. An online survey revealed energy efficiency and green building, along with automation, were the subjects likely attendees are most curious about.
“Given the high cost of fuel and the ongoing desire for more healthy living environments, there is a critical need to learn more about the products, technologies and trends that can help achieve greater energy efficiency,” Stevens said.
The U.S. Green Building Council, which created the Leadership in Energy and Environmental Design building-rating program, will sponsor several sessions.
ASHRAE sessionsAs has long been the case, the American Society of Heating, Refrigerating and Air-conditioning Engineers will hold its winter meeting before and during the event. Many of its technical discussions will take place at the Adams Mark Hotel. Here’s a look at some of the many ASHRAE-sponsored sessions planned during the event.
At 7:45 a.m. Jan. 28, these sessions are scheduled.
- “Numerical Modeling of Noise and Vibration in HVAC Systems.” Trane Co.’s William B. Rockwood will lead this discussion on using computer modeling to determine sound and vibration levels. Alternative methods will also be discussed.
- “New Energy Efficiency Tools for Sustainable Building Design.” This session will explore the new technology of combined heat-and-power systems. Recycled power and chilled water will be among the topics discussed. Richard Sweetser of Exergy Partners Corp. in Herndon, Va., will lead the talk.
- “Ventilation and IAQ in Apartment Buildings” will be led by Steven J. Emmerich from the National Institute of Standards and Technology. There are more than 7 million multifamily dwellings in America, yet ASHRAE officials say air quality in them has not been well studied. Although the society has standards for them, guidelines are minimal. Recent studies on controlling drifting tobacco smoke and other ventilation problems will be showcased.
- At 10:45 a.m. Jan. 28, “How Low Can You Go? Low-Energy Buildings Through Integrated Design” is scheduled. The U.S. Department of Energy’s Drury B. Crawley will lead this discussion on the effectiveness of “green” buildings. Designs, performance, measurements and technology will be among the topics.
- At 3:15 p.m. the same day, “Seasonal Energy Efficiency Rating Issues” will discuss the new technology and government-imposed performance standards. A talk on product limitations and performance predictions will be led by Carl F. Huber, P.E., of WaterFurnace International Inc.
- At 7:45 a.m. Jan. 29 will be part one of “Learning from History: It’s All Been Done Before.” This session, led by Wallace L. Donley, will demonstrate that problems with humidity and airflow aren’t new. In fact, they go back to ancient times. Learn how the Romans dealt with heating and cooling issues.
- ASHRAE’s sometimes-controversial Standard 62 will be the topic of “The Future of Standard 62.1?” at 7:45 a.m. Jan. 29. The rule, which deals with indoor air quality, has been the subject of much scrutiny from anti-smoking activists and others in recent years. This off-the-record discussion will allow attendees to discuss their problems with the standard and offer suggestions. Richard D. Hermans, P.E., of the Minneapolis-based Center for Energy and Environment will moderate.
- Air quality will also be a major focus of “Environmental Health: Particulate Matter Sources, Health Effects and Control Strategies,” at 7:45 a.m. Jan. 30. Wane A. Baker, P.E., of Michaels Engineering in La Crosse, Wis., will lead the talk. Research has given occasionally conflicting answers on the health effects of some indoor particulate matter. This session will explain the latest research on this type of pollution and what purification systems can do, if anything, to improve the situation.
- At 10:45 a.m. Jan. 30, “Case Studies of HEPA Filter Design and Installation Challenges,” will cover the use of high-efficiency particulate air filters in industrial settings. Engineering problems typically encountered will be profiled. U.S. Energy Department employee Douglass S. Abramson will act as chairman.

Sidebar: Many new items to be displayed at showFor many attendees, the AHR Expo is all about products. Thousands are expected to be on display, many of them featuring the newest technology.
Here are a few of the products exhibiting companies have told Snips will be shown.
Pressure-measurement device makerSetra Systemswill show the Model No. 260 low-differential pressure transducer. With selectable pressure, it includes analog outputs, an LCD screen and AC/DC voltage operation. The unit can be reconfigured easily, with separate slide switches for range selection, analog output and directional ranges.
Patterson Pump Co.’sPro-Max horizontal, split-case HVAC pumps have a high-efficiency design to minimize energy consumption. And when it needs to be serviced, technicians can easily access it without disturbing piping connections. Precision-made, they minimize vibration and improve bearing life.
