The latest Copeland Scroll variable-speed compressor from Emerson Climate Technologies took top prize in the annual AHR Expo Innovation Awards.

The second-generation compressor can achieve a seasonal energy-efficiency rating of more than 25 and a heating seasonal performance factor of 13.

It also won in the awards’ cooling category.

“In 2011, our first generation variable speed technology created an entirely new experience for heat pump owners by enabling 20 SEER, hot-air supply and industry-leading 13 HSPF,” said Brandy Powell, vice president of the variable speed division at Emerson’s air-conditioning business. “With our next generation variable speed technology, we’ve pushed the envelope even further by enabling system manufacturers to achieve industry leading performance in both heating and cooling in addition to enhanced comfort and reliability. Our goal was to ensure homes and small businesses stay comfortable and save money — regardless of the conditions outside.”

In the building automation category, Belimo’s energy valve was the winner. It is a hydronic heating/cooling load measuring and control valve that communicates with building automation systems to coil performance.

Lafert North America high performance metric motors won the green building prize. They offer speeds from 1,500 to 4,500 rpm and metric frame sizes from 71 to 132. The motors are suited for heat pump, compressor and fan situations where reduced size, weight and operating costs are desired.

In the heating category, WaterFurnace International’s 7 Series 700A11 variable capacity geothermal heat pump won for its use of two-way communications, energy monitoring and integration with home automation systems.

Neptronic’s SKD direct steam-injection humidifier won in the indoor air quality category. It injects and disperses low-pressure boiler steam into the air supply to humidity levels.

Danfoss’ ADAP-Kool AK-SM 800 supermarket refrigeration control system took the refrigeration category’s top prize, and marks the 16th such award the company has earned in the last 11 years. The system can be controlled over the Internet, making it flexible for service technicians and permitting building owners to monitor conditions from almost anywhere.

Danfoss North America President John Galyen thanked the award organizers for the prize.

“It is an honor to be recognized in the Innovation Awards competition again this year,” Galyen said. “Danfoss has developed a strong history with the competition, underscoring Danfoss’ ability to engineer innovative and reliable technologies and solutions that represent our commitment to energy efficiency and environmental responsibility. By responding to customer and market needs through product innovation, Danfoss is able to deliver improved business performance and operational savings.”

Big Ass Fans’ Haiku ceiling fan won the ventilation prize. Environmentally friendly and very quiet, its motor is made for long life.

Among tools and instruments, the iManifold from Imperial was given top honors. It is a smartphone-compatible digital refrigeration manifold that wirelessly displays a system’s pressures and temperatures while figuring performance targets.

In software, Revit Connection version 2.0 from HVAC Solution was picked for the prize. It is add-in software for Autodesk Revit and building information modeling schematic and schedule making. It brings in air, hydronics, steam and control data and maps HVAC components.

In plumbing, Rheem’s Prestige series hybrid electric residential water heater has a color backlit touch screen that shows service alerts for homeowners and diagnostic information for contractors. It includes five operation modes.

The contest is sponsored by the International Exposition Co., the Air-Conditioning, Heating and Refrigeration Institute and the American Society of Heating, Refrigeration and Air-Conditioning Engineers. Applicants are judged on user value, market application and impact. Thirty-six products receives honorable mentions.

Entry fees from the contest are given to a charity in the AHR Expo’s host city.

“The Innovation Awards play a very important role in the HVACR industry,” said Clay Stevens, president of the International Exposition Co., which produces and manages the expo. “In addition to recognizing and encouraging new product innovation, the proceeds benefit charitable organizations throughout the U.S.”
