NREL Develops New Air Conditioning Process That Saves 90% of Energy

The National Renewable Energy Lab has developed a new kind of air conditioning process that can help save about 90 percent energy.Since a major percentage of the energy consumed by an average householdis used up in cooling, 90 percent savings will definitely be huge. These researchers have invented a new process that uses membranes,evaporative cooling and liquid desiccants in a way that has never beendone before.

The technologysolves the issues related to evaporative cooling A/Cs that add humidityto their cool air output and hence can only be used in dry areas. Thenew technology dubbed DEVap uses liquid desiccants to remove humidityfrom the air that has been cooled down.

The DEVap uses salt solutions rather than any harmful refrigerantssuch as CFC or HCFC, a pound of which contributes as much to globalwarming as 2000 pounds of carbon dioxide. NREL is trying to improve thetechnique for a few years before licensing it to the industry.
