    AHR EXPO 2012 Shines a Light on Industry

    March 1, 2012
    Chicago is a blues town, but they were kept at bay during the 2012 International Air- Conditioning, Heating, Refrigerating Exposition. Thousands of HVACR professionals made the journey, seeking new products and ideas to grow their businesses

    In spite of continuing economic challenges, thousands of HVACR professionals flocked to Chicago’s McCormick Center for 2012’s AHR Expo. Nearly 2,000 companies showcased their latest products and technologies on more than 429,000 sq.ft. of exhibit space. This made the AHR Expo the largest event in its 82-year history. Yes, that meant more walking, but there were also more new products to see, so it was worth the sore feet.

    The AHR Expo is never a disappointing event. Every year, it features innovative products, and we always meet interesting people. Expo officials’ final report said the show drew nearly 40,000 contractors, engineers, facility managers, and other HVACR professionals.

    Contracting Business.com editors spent three days covering the event, and we now present our “travelogue” of activity, to give you an idea of the products and people that made 2012 AHR Expo a winner. Among some of the really interesting products we saw and news we uncovered were the following:

    The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) reported that 2,800 people attended the ASHRAE Winter Conference, held Jan. 21-25, as part of AHR Expo. The top-attended sessions were selection of proper chiller technology; thermal displacement ventilation applications; heat pump optimization; air source versus ground source heat pump systems; integrated design energy retrofits; and water-cooled VRF systems.

    Other conference highlights included the technical plenary, which drew 600 attendees, with its focus on Chicago’s energy-efficient economic model for sustainability.

    ASHRAE announced a brand repositioning with a refreshed logo, a new tagline, and a change to using only its acronym.

    “ASHRAE’s original commitment to HVACR engineering excellence remains resolute, even as the Society continues to expand its influence into all facets of building design, construction, reconstruction, and operation,” ASHRAE President Ron Jarnagin said.

    “Just as integrated design is the cornerstone of sustainable buildings, ASHRAE members create an integrated body of knowledge to make buildings as high performing as possible.”

    And now, on to the exhibits:

    Rheem continued its ground-breaking product rollout when it unveiled the first-of-its-kind Rheem H2AC rooftop unit with eSync integration technology. Designed for full-service restaurants, this integrated system delivers air conditioning and water heating from a single source. The system works by using the heat removed from the HVAC system — which would normally be rejected into the atmosphere — as a way to heat water.

    “Considering that today’s full-service restaurants are struggling with rising energy costs, there’s a strong, immediate opportunity for a system like the Rheem H2AC rooftop unit to make a real impact on an owner or franchisor’s bottom line,” said Chris Peel, Rheem’s senior vice president and chief operating officer. Also on display was the Rheem Prestige series modulating 95% AFUE gas furnace. A conventional furnace is either “off” or “on” at 100% capacity, depending on the demand for heat. The Rheem Prestige series modulating gas furnace works differently because it uses modulation technology, so it’s seldom “off” or “on” at 100%. Contracting Business.com magazine named this unit a 2011 Mechanical Systems Week Product Showcase Award Winner in the category of Forced-air Heating Equipment, and attendees at this year’s AHR Expo could see why!

    Speaking of compressors, one product that caught our attention as we cruised the show floor was the spool compressor by a company called Torad. Spool compressor? The company calls this the next generation in refrigeration compressor technology. We spoke with company president, Joe Orosz, who explained that, since 2007, the research and development team has worked diligently to produce several working prototypes in finalizing the design of the spool compressor. “It’s important to us at Torad to listen to the needs of the HVAC industry, and provide a product that will offer incredible advantages to the complete design. It’s perfect timing to introduce this viable engineered alternative, especially one that can dramatically cut compressor cost of over 25%, and decrease the physical size and weight, all without sacrificing any of the performance areas,” Orosz said.

    Torad’s design includes four main components: rotor, main housing, gate, and bearing housings. The components make up a single rotating spool assembly for the compressor. Greg Kemp, CEO and inventor of this technology, said the spool compressor combines the positive sealing of a piston compressor with the reliability of a screw or scroll compressor. He added that the Torad device achieves high efficiency levels over a wide range of sizes.
