The Environmental Protection Agency has approved a Kane'ohe man's homemade formula for a refrigerant in home appliances and air-conditioners that is safer for consumers and the environment.
Richard Maruya designed his HCR-188c hydrocarbon blend as a replacement for refrigerants that deplete the Earth's ozone layer and/or contribute "greenhouse" gases to the atmosphere. His precise mixture of ethane, propane, isobutene, normal butane and other naturally occurring compounds has zero ozone-depleting potential and very low global warming potential.
And, because appliances using HCR-188c require only one-quarter of the usual amount of refrigerant, the danger from fires and leaks is extremely low. Independent testing also has shown that appliances with HCR-188c use less energy and provide a greater degree of cooling.
In April, Maruya was honored with the 2008 Environmental Achievement Award from EPA's Region IX office for his "innovative research" and "unwavering commitment to achieve this environmentally friendly product."
