New A/C Process May Cut Energy Use 50% – 90%

Latest News > Industry News

June 22 — A new air-conditioning process has the potential to cut energy use by 50% – 90% compared to today's best units, says the inventor of the process, the National Renewable Energy Laboratory (NREL) of the U.S. Department of Energy (DOE).

The process—named the desiccant-enhanced evaporative air conditioner (DEVap)— uses membranes, evaporative cooling and liquid desiccants in a way that has never been done before, according to an NREL news release.

"The idea is to revolutionize cooling, while removing millions of metric tons of carbon from the air," said Eric Kozubal, NREL mechanical engineer, one of the inventors of the DEVap.

"We've been working with membranes, evaporative coolers and desiccants, Kozubal added. "We saw an opportunity to combine them in a single device for a product with unique capabilities.

NREL plans to license the technology to industry at some point.
