The frosty weather in Chicago did not keep visitors away from the 2003 Air-Conditioning, Heating, Refriger-ating Exposition. The AHR Expo, sponsored by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers and the Air-Conditioning and Refrigeration Institute, had record attendance and exhibitors, according to the International Exposition Co., which produced and managed the HVACR showcase.

As of this writing, more than 38,000 registered visitors from 117 countries came to the three-day event to see thousands of the latest products and technologies displayed by more than 1,860 exhibiting companies.

Besides several new product releases, the Hydronics Institute (HI) Division of the Gas Appliance Manufacturers Association (GAMA) announced at the show that this is the year the I=B=R training seminars will return to the industry.

The schools, which began more than 50 years ago and have presented over 1,500 training seminars to 60,000 students, had been put on hold in 1995 when attendance dropped significantly. Around the same time, HI joined with GAMA and a commitment was made to change I=B=R's curriculum. With the addition of "Guide 2000," a heating installation and design textbook created with the help of the current 65 manufacturing members of the group, the training is ready to hit the road again.

HI plans to run 30-40 schools a year in cities around the country. A two-day course on installation and design of residential systems is first. A course on commercial and special installation applications is intended, but not this year.

At the show, it was announced that classes would be held late April, early May, but as of this writing no specific dates were available. HI hopes to offer more classes in late spring and fall of this year. Cost for attending the school is $395 and includes "Guide 2000."

"I-B-R's content will be controlled carefully by GAMA and HI," said Joe Coppola, education chairman for HI.

Details about dates and locations will be posted as they become available. For further information about I=B=R, HI, GAMA or "Guide 2000," visit the GAMA Web site at
