Dais Fluorocarbon-Free Technology Helps Resolve Copenhagen-15 Dilemma
Tuesday October 6, 2009, 10:33 am EDT

ODESSA, Fla.--(BUSINESS WIRE)--Dais Analytic (DLYT), a US nanotechnology company is prototyping a fluorocarbon-free heating and cooling system called “NanoAir” that uses water instead of traditional CFC/HCFC-producing refrigerants that deplete the ozone layer.

This may be a timely breakthrough for the upcoming Climate Change Conference in Copenhagen. The impact of these chemicals on global warming will be a major topic when representatives from 170 countries unite again in what has been, for the last 22 years, one of the most focused global efforts in history.

Despite this determination, emission reduction has remained elusive.

“Progress toward high industrialized world emissions cuts remains disappointing during these pre-Copenhagen talks. We’re not seeing real advances there,” said Yvo de Boer, head of the Climate Change Secretariat at the current Bangkok negotiations, the last stop before Copenhagen.

Sixty-five percent of the world’s production of CFC/HCFCs comes from the heating, ventilation, air conditioning and refrigeration sector (HVAC/R) the largest source of ozone-depleting fluorocarbons.

NanoAir’s breakthrough is to eliminate the use of fluorocarbons, and Dais expects that it will reduce energy consumption by 50% or more with projected Seasonal Energy Efficiency Ratings (SEER) greater than 30, and Energy Efficiency Ratings (EER) in the mid-twenties.

AHRI President Stephen Yurek last month addressed the use of fluorocarbons at an HVAC/R industry meeting at the United Nations Environment Program conference in Milan. He said “we must ensure the use of HFCs is phased down” which he acknowledged is not an easy task. He concluded his remarks with a call for a partnership between government and industry researchers to explore alternative refrigerants for the future.

NanoAir uses key Dais nanotechnology in commercial use in the Company’s ConsERV energy recovery ventilator being marketed in North America.

“NanoAir and ConsERV together address Mr. Yurek’s comments. These products can lead the HVAC/R industry’s shift to using nanotechnology materials with all its attending benefits,” said Scott Ehrenberg, Dais’s Chief Technology Officer. Continuing Ehrenberg said “This innovative system may completely replace less energy efficient, century-old, refrigerant loop based heating, ventilating, and air-conditioning equipment.”

In August 2009, Dais signed an agreement with Genertec America, a subsidiary of the Chinese State-owned China General Technology (Group) Holding Ltd, to provide NanoAir and other Dais green technology to China.

“In seeking answers to complex energy and environmental matters such as the reduction of fluorocarbon-producing equipment, the world community needs a fresh approach, using a mixture of current and new industry participants. Dais brings this fresh approach by using its family of nano-materials with properties unlike any previously existing material,” said Yuen Kong, Chief Strategy Officer, Genertec-America.

“If the whole world comes to Copenhagen and leaves without making the needed political agreement, then I think it’s a failure that is not just about climate….that is and should not be a possibility. It’s not an option,” said Connie Hedegaard, president of COP-15.

Perhaps NanoAir technology will provide a new option for COP-15 – just in time.

Dais Analytic Corporation is a nanotechnology materials and products company. Products incorporating the Dais family of materials minimize consumption of irreplaceable natural resources and stop the degradation of our environment.
