Daikin is Danfoss EnVisioneer of the Year3rd December 2014
USA: Daikin Applied has won a Danfoss EnVisioneer of the Year award for the use of Turbocor compressors in its Magnitude chiller.
Launched in 2010, the EnVisioneer of the Year award recognises North American end users, municipalities, building owners, or original equipment manufacturers that have introduced a new product, opened a new facility, or invested in a building or system upgrade using Danfoss products or solutions to realise significant energy and/or environmental savings. The competition is judged and the winner is chosen by an independent third party.
Daikin Applied, the former Daikin McQuay business, uses the energy-effcient Danfoss Turbocor variable speed, oil-free, magnetic bearing centrifugal compressors in its water-cooled Magnitude chillers.
Three 250-ton Daikin Magnitude chillers were installed at the 207,000ft2 Orlando Science Center to replace the eight failing water-cooled screw chillers installed in 1996. The new system alone provided estimated energy savings of 30%, but, when combined with the control of a building automation system, the chillers are said to have been able to reduce electric costs by 50% compared to the old system.
Two 280-ton Daikin Magnitude chillers also are helping to reduce operating costs of the Hotel Nikko San Francisco, a 25-story, 533-room, hotel near Union Square. In addition to replacing the building’s aging and unreliable chillers, Hotel Nikko also wanted to find a way to reduce its carbon footprint. It chose Daikin Magnitude chillers for their ultra-quiet operation, use of R134a refrigerant, and reduced maintenance needs. The new Magnitude chillers provided annual energy cost savings of 15.2% and helped Hotel Nikko become a seven-time recipient of the U.S. EPA Energy Star Award as well as obtain a rebate from the local utility for five percent of the total installation cost.
In addition, with an Integrated Part Load Value (IPLV) as low as 0.29, Magnitude chillers meet and can exceed the chiller efficiency standards set forth in ASHRAE 90.1-2015.
“For the past four years, the EnVisioneer of the Year award programme has been recognising industry-leading or game-changing investments and improvements in energy efficiency and environmental responsibility,” said John Galyen, president, Danfoss North America. “We’re pleased to recognise Daikin Applied with our fifth annual award for its development of a chiller technology that has proven to dramatically improve building energy use and indoor climate.”
