Sea Water Cooling Slashes Data Center Energy Costs
Interxion, the European data center operator, has cut energy bills Stockholm data center through a million dollars through a number of steps, but especially with the use of sea water is too cold. Stockholm data center opened in January 2009 and at the time it was one of the first data center that uses sea water cooling systems.
The Stockholm data center, Interxion claim, is now operating at a very low PUE and consistent, not changing due to improving PUE energy for cooling during the summer and use 100 percent renewable energy. They also use a continuous monitoring of the environment help them improve the efficiency and the use of a modular architecture to optimize the use of electricity has gradually effectiveness.
The company highlights the use of sustainable energy such free cooling, water cooling and waste heat re-use of the land on which their center, but then they claim it was never at the expense of reliability and availability. Many of their centers, such as Copenhagen, London and Amsterdam using 100 percent renewable energy.
But is the use of seawater to chill Inerxion claim to have the greatest impact on reducing energy costs, giving them 80 percent . reduction In Stockholm, water entering the first facility to six degrees Celsius and 12 degrees out, according to IDG. The water is then pumped to the second site, which is set at 18 degrees, and then a third set at 24 degrees. And finally the water is then sent to a heat pump is used to heat local homes and offices. “Interxion Before starting this project,” IDG report continues, “The energy bill of about U.S. $ 2.6 million per year to relax 1 megawatt of IT load. Today, the energy bill cool $ 1,000,000 1 megawatt of IT load, which means that the system has saved approximately $ 1.6 million per year per megawatt. “Sea water is an attractive option for data center cooling. Among other things, the Mauritius Eco-Park project has been promoting this option aims to capitalize on his way to the position of the island ocean waves. And I also have been using sea water to chill the data center Finland.However there are other costs that need to be considered to find a data center near the sea. Cost can be a source of high ground, and the necessary infrastructure will also be more expensive. Plus a contingency plan should be available if the pumps pumping sea water as an island continent fail.Australia with a high percentage of the population on the beach looks like a perfect candidate to use this technology to bring efficiency.
