Groundbreaking Air Conditioning Technology Uses Desiccants

National Renewable Energy Laboratory (NREL) researchers have invented a breakthrough technology that improves air conditioning in a novel way – with heat. NREL combined desiccant materials, which remove moisture from the air using heat, and advanced evaporative technologies to develop a cooling unit that uses 90% less electricity and up to 80% less total energy than traditional air conditioning. The new solution, called the desiccant enhanced evaporative air conditioner (DEVAP), also controls humidity more effectively to improve the comfort of people in buildings.
