This article was originally published on coolingpost.com on May 10, 2020. USA: A Harvard University team has developed an indirect evaporative cooling system which can cool air without adding humidity at a fraction of the energy cost of traditional cooling units. Evaporative cooling is a well established technology which works well in a number of … Read more
This article was originally published on pnnl.gov, May 6, 2019. PNNL researchers Jianming Lian, Karanjit Kalsi, joint appointee Wei Zhang, and former PNNL intern Sen Li recently received a patent for a market mechanism consisting of novel bidding and clearing strategies. These strategies—for the first time—systematically incorporate the internal dynamics of thermostatically controlled loads, or … Read more
This article was originally written by Genoa Blankenship, pnnl.com, July 8, 2019 Greek mathematician and physicist Archimedes set off an historical evolution of the mechanical pump after he invented the screw pump around 200 BC. Despite the universal presence of the mechanical pump, a tool for moving gas or liquid, a replacement has long been … Read more
Cool homes, hot planet: How air conditioning explains the world Washington Post, April 27, 2015. Image credit: PublicDomanArchive Air conditioners in the United States are commonplace — they’re in some 90 percent of our homes, where they consume 5 percent of total U.S. electricity. But we’re not where the growth will happen. Rather, it’s in warm … Read more
Polariton refrigerator could chill tiny semiconductor devices Physics World, May 15, 2015. Image credit: geralt A new method for using light to cool solids has been created by physicists in France and Germany. The technique uses quasiparticles called “polaritons” to remove vibrational heat from a tiny piece of semiconductor, and unlike previous optical cooling schemes … Read more
New Tool Maps Buildings’ Energy Efficiency Voice of America News, February 26, 2015 Architects, engineers and building managers will soon be able to quickly collect data about building interiors that once took weeks to measure and process. A backpack-mounted device, developed by a group of scientists at the University of California, Berkeley, will require … Read more
Emerson Network Power is building a research and development center on the University of Dayton campus in Ohio where it will have a dedicated facility for developing new data center cooling technology.
As engineers work to lessen the massive energy demands of data centers — which, the EPA estimates, already gobble up a whopping 3% of all electricity consumed in the U.S. — these facilities are getting warmer. This allows data center operators to save big on cooling costs and energy demands.
