With global warming looming, one of the biggest dangers to the environment are air conditioners. Things get hotter, they're used more often, more pollutants are released, things heat up more, and then the AC units again are used more. It is a vicious cycle. But there is hope.
The U.S. Department of Energy’s National Renewable Energy Laboratory has invented a new air conditioning process with the potential of using 50 percent to 90 percent less energy than today’s top-of-the-line units. It uses membranes, evaporative cooling and liquid desiccants in a way that has never been done before in the centuries-old science of removing heat from the air.
Not only does this system pose a great advantage in energy savings, but also there are no harmful chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) to worry about. A pound of CFC or HCFC in refrigerant-based A/Cs contributes as much to global warming as 2,000 pounds of carbon dioxide. A typical residential size A/C has as much as 13 pounds of these refrigerants.
