CHICAGO - If you've been to more than a few AHR Expos, you know that Chicago, unfortunately, is one of the best venues for this event. McCormick Place convention center is huge and accessible, and the city has enough hotel rooms and restaurant chairs to handle all show attendees plus the locals.

Yet without a Midwesterner's fortitude, Chicago can be an unforgiving place to spend late January. If it warmed up another 20 degrees, it could be considered "cold," but at prevailing winds and temperatures, it's just plain nasty.

Organizers of the 2003 International Air-Conditioning, Heating, Refrigerating Exposition expect this year's show to become one of the largest in its history when it convenes Jan. 27-29 in the north and south halls of Chicago's McCormick Place.

Some 1,400 exhibitors are expected to fill 400,000 sq. ft. of space. More than 30,000 attendees and 25,000 exhibitor personnel are scheduled to attend.

"Our largest AHR Expo was in Chicago in 1999, and we could challenge those records when we return to McCormick Place next year," said Clay Stevens, president of International Exposition Co., producers and managers of the AHR Expo.

The 1999 show attracted more than 58,000 hvacr professionals and occupied about 399,000 sq. ft. of exhibit space. The second-largest AHR Expo was held in Atlanta in 2001 and featured 385,000 sq. ft. of exhibit space.

Seventeen industry associations have endorsed the event, including Air Conditioning Contractors of America, Air-conditioning and Refrigeration Wholesalers International, Gas Appliance Manufacturers Association, Mechanical Contractors Association of America, and Refrigeration Service Engineers Society.

The AHR Expo attracts contractors, consulting engineers, dealers, distributors, wholesalers, oem's, architects and builders, industrial plant operators, facility managers, agents, and representatives.

Show seminars

Association-sponsored seminars will be conducted during the show to educate attendees on popular topics of interest. Some of those seminars include the following:

  • Basics of Clean Air: Air filtration principles along with best practice techniques and applications, sponsored by the National Air Filtration Association.

  • Louvers - What you should know before you buy or specify,
  • What Constitutes a Quality TAB Report? Information to owners, engineers, and installing contractors regarding the roles and responsibilities that they have in getting a quality testing, adjusting and balancing report. A discussion will include tips to help ensure that projects receive a quality TAB report.

  • Return of I=B=R Residential Hydronic Heating: Fundamentals of design and installation of residential boilers and heating systems, sponsored by GAMA.

  • Humidity Control I - Basic Principles, Loads and Equipment; 2 p.m. to 5 p.m. Jan. 26.

    In commercial buildings, excess humidity and moisture problems have caused difficulties with mold, mildew and uncomfortable conditions for occupants. This course, based on ASHRAE's new "Design Guide for Humidity Control," will help the designer achieve true control of humidity rather than just its moderation. The course will cover how to remove moisture loads with equipment dedicated to that purpose alone, rather than relying on the occasional dehumidification effect of a building's cooling system.

    Attendees will learn what equipment is used for this purpose, how it works and how to apply it quickly, economically and reliably. The instructors are William M. Worek, Ph.D., University of Illinois - Chicago, and Mark Nunnelly of Nunnelly & Associates Inc.

The course will then illustrate that, once a shift in the design paradigm in favor of a separate DOAS has occurred, questions concerning the thermodynamic state of the delivered ventilation air arise.

    Some of the boundary conditions that impact the best state of the delivered ventilation air will be addressed. The instructor is Pennsylvania State University Professor Stanley A. Mumma, Ph.D., P.E.
