Dais Analytic Develops First-Generation NanoAir Air Conditioning System Based on Patented Aqualyte Nanotechnology

(Nanowerk News) Dais Analytic Corporation announced today it is successfully operating a heating, ventilation, air conditioning and refrigeration (HVAC/R) beta unit employing its Aqualyte™ nanotechnology materials using no refrigerant gases. The system, dubbed "NanoAir", is projected to reduce energy usage and harmful emissions by over 50% from today's most efficient heating/cooling, and refrigeration equipment. It creates a comfortable environment by managing a room's temperature and humidity levels. NanoAir is fully capable of heating, cooling, dehumidifying, or humidifying air using water and Dais's nano-materials rather than ozone-depleting fluorocarbon (CFCs and HCFCs) refrigerants commonly used in today's cooling/refrigeration equipment.
The NanoAir beta unit will be showcased at the Department of Energy's Advanced Research Project Agency -- Energy's "Energy Innovation Summit" being held February 28 through March 2, 2011, in Washington, D.C. Dais was awarded a $680,000 ARPA-E grant from the US Department of Energy in September, 2010, to accelerate NanoAir's commercialization.
Scott Ehrenberg, Chief Technology Officer, said, "NanoAir is the next breakthrough use of Dais' nanotechnology materials. NanoAir has been shown by third party testing to have the ability to reduce energy costs and harmful emissions by over 50% versus equipment in use today."
David Longacre, Dais' Vice President of Sales & Marketing, said, "Preliminary discussions held with our sales organization at the International Air Conditioning, Heating, Refrigerating (AHR) Exposition in Las Vegas earlier this month included the integration of key NanoAir components into the Company's award-winning ConsERV energy recovery ventilator product line and were incredibly well received." ConsERV is used in schools, offices, hotels, and other commercial buildings as well as homes to pre-treat ventilation air's temperature and humidity content to lower energy consumption and reduce capital costs of HVAC equipment. Longacre continued, "The sales team is excited because they will be able to offer their customers a truly differentiated solution having higher energy efficiencies and a much better carbon footprint in a simple all-in-one package. This is the beauty of nanotechnology."
The U.S. Energy Information Administration (EIA) reports that energy use for heating and air-conditioning accounts for more than 25% of the primary energy consumed in roughly 78 billion square feet of commercial building floorspace in the U.S., resulting in more than 248 million metric tons of CO2 emissions, or approximately 23% of all commercial building CO2 emissions.
The NanoAir HVAC/R system will play a key role in the energy efficiency equation towards achieving zero-energy buildings in the U.S. and worldwide. NanoAir is projected to reduce HVAC energy consumption and carbon footprint in excess of 50%, while providing superior comfort and indoor air quality (IAQ).
Using Dais' Aqualyte membrane -- a nano-structured material, NanoAir is engineered to be a useful replacement for stationary heating/cooling products while allowing for newer innovative installation approaches including nearly all forms of refrigerant-based equipment found in the transportation and food industries.
About Dais Analytic Corporation
Dais Analytic Corporation is commercializing its nanotechnology materials and processes into evolutionary or disruptive air, energy or water applications. The applications include ConsERV™, commercially available, which pretreats incoming building air for most Heating, Ventilating, and Air Conditioning (HVAC) equipment with the energy found in the exhaust air thus lowering HVAC capital equipment, maintenance costs, and emissions. The Company is in various stages of development of NanoAir, a disruptive water-based, no refrigerant gas refrigeration cycle usable for nearly every air conditioning and refrigeration use (co-funded by the US DoE 'ARPA-E' program); NanoClear™, a simpler method of treating most forms of contaminated water (sea, waste, industrial) to provide 1,000 times cleaner potable water; and NanoCap™, a disruptive energy-storage device. Each application underscores the diversity of Dais' core product, Aqualyte™ -- a family of nano-structure polymers and processes -- by focusing on minimizing consumption of irreplaceable natural resources and stopping the degradation of our environment.
