Project Objective

Electric Power Research Institute Inc., working with Oak Ridge National Laboratory (ORNL), Optimized Thermal Systems, Southern Company, and Tennessee Valley Authority March (TVA) will design, construct and test the concept of using nanostructures to enable noncondensing air dehumidification through electrostatic molecular sorting. The project approach will overcome the main challenge in electrostatic dehumidification by improving condensation through sorting the molecules on a nanoscale device.

Project Impact

This project could eliminate about 1.45 quads of energy. Additionally, if dehumidification is separated from sensible cooling, then vapor compression systems could be operated at a higher evaporation temperature, lower compression ratio, and higher coefficient of performance (COP).
