North American Data Centers Save Over 1 Billion Gallons of Water Using Emerson Network Power Cooling System
Use of Liebert® DSE pumped refrigerant economization system reduces energy and water usage.
Emerson Network Power has announced that the deployment of the Liebert® DSE pumped refrigerant economization system in North America has saved over 1.4 billion gallons of water in the last 36 months, compared to using data center chilled water cooling systems, and is expected to save an additional 1 billion gallons of water in 2016.
“For nine months, Emerson and Digital Realty, a leading global provider of data center solutions, worked together to explore the energy savings and operational performance of a pumped refrigerant system and compared it to that of a chilled water system. The results proved to be promising, and the companies shared them with the California Energy Commission and applied for a formal exception to the air- and water-only rule in place at the time,” said Aaron Binkley, director of sustainability at Digital Realty. “We found that, in addition to energy savings, the system delivered another benefit that has since come to be highly valued in California because of the current drought conditions — it saves millions of gallons of water.”
