Description:

Two new nonflammable, nontoxic, nonfractionating, environmentally safe, medium- pressure refrigerant blends with performance superior to CFCs, HCFCs, HFCs, and other alternatives have been discovered. These refrigerants, called Ikon A and B, have attractive physical properties, zero ozone depleting potential, and very low global warming potential and total equivalent warming impacts (TEWI). Both appear superior in performance and environmental properties to any other alternatives available. They have been shown to have high thermal stability, low toxicity, and good compatibility with commercial materials. They could eliminate the need for the global warming refrigerant R-134a and the ozone-depleting refrigerant R-12 and allow improved energy efficiency, which will reduce fuel consumption and the amounts of CO2 produced. Although they appear suitable to replace R-134a and R-12 in domestic refrigerators, Ikon A and B have not yet been tested for this use. Tests by the EPA, Dole Foods, and Environmental Technology and Education Center (ETEC) have shown that Ikon refrigerants have 10-30% better energy efficiency than current refrigerants. In Phase I the technology will be reviewed, a refrigerator will be instrumented, baseline performance data with R-134a and R-12 will be collected, performance data with Ikon refrigerants will be obtained, and TEWIs will be calculated.
