NanoAir HVAC technology transfers water molecules through a patented nanostructured polymer membrane to give the user independent control of humidity and temperature without using any conventional fluorocarbon refrigerants. This membrane allows very rapid and selective permeation of water molecules through a solid plastic exposed to small vapor pressure differences, enabling isothermal dehumidification of air streams and evaporative cooling below local dewpoint temperatures.
The project team will construct a fully functional packaged rooftop unit (RTU) that will be thoroughly tested and evaluated at Oak Ridge National Laboratory (ORNL). The unit will demonstrate Technology Readiness Level 6 (TRL-6) by operating at scale in a controlled environment and provide a clear path to deploying TRL-7 pilot installations.
The goal is to demonstrate improved comfort and control with a system that eliminates climate-sensitive refrigerants and demonstrates a 30 – 50% reduction in electrical consumption from today’s RTUs. The technology can be applied in many different configurations across the HVAC cooling market, which accounted for 5.68 Quads of primary energy in 2011 (14% of building energy consumption), with further uses in both heating and refrigeration.
