BALTIMORE — Danfoss has announced that Daikin Applied is the winner of its fifth annual EnVisioneer of the Year award competition. Daikin Applied is using Danfoss Turbocor variable speed, oil-free, magnetic bearing centrifugal compressors in its water-cooled Magnitude® chillers to help building owners reduce electricity consumption and greenhouse gas emissions, and save operating costs over the lifetime of the chiller by minimizing maintenance.
Danfoss noted that today more than 3,000 Daikin Magnitude chillers have been installed around the world and are significantly improving energy use — consuming as much as 40 percent less in comparison with the conventional chiller technology that was replaced or displaced.
For example, three 250-ton Daikin Magnitude chillers have helped to substantially cut energy use and improve comfort at the Orlando Science Center in Orlando, Florida — a 207,000-square-foot facility opened in 1996. When the eight original water-cooled screw chillers began to fail, causing the center to provide free bottled water to visitors to help keep them comfortable during their visit, the Orlando Science Center chose to replace the original chillers with Daikin Magnitude magnetic bearing chillers, which can operate on part-load capacity to improve efficiency and extend chiller life. The new system alone provided estimated energy savings of 30 percent, but, when combined with the control of a building automation system, the chillers were able to reduce electric costs by 50 percent 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, Four Diamond Award®-rated 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 R-134a refrigerant, and reduced maintenance needs. As a result, the new Magnitude chillers provided annual energy cost savings of 15.2 percent, and helped Hotel Nikko become a seven-time recipient of the U.S. Environmental Protection Agency’s (EPA’s) Energy Star® award as well as obtain a rebate from the local utility for 5 percent of the total installation cost.
Plus, 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 program has been recognizing 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 recognize 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.”
