Environmentally friendly refrigerants

EPA proposed to add the type of environmentally friendly refrigerants

In order to support President Barack Obama's "Climate Action Plan", the U.S. Environmental Protection Agency (EPA) recently proposed to increase the types of alternative refrigerants to protect the ozone layer, to better protect the climate.

In the same industry, environmental organizations and other deliberations, EPA proposed to select some have low GWP hydrocarbon refrigerants to replace the list included (see Table) in six categories refrigeration and air conditioning applications. This application includes six categories: single commercial and home freezers and refrigerators, ultra-low temperature freezers, non-mechanical heat exchanger, vending machines and indoor air conditioning units. Plan also includes a lower GWP with hydrofluorocarbon refrigerants HFC-32, the refrigerant which has been in Europe and Asia, widely used in many refrigeration equipment.

This is the first action under the EPA "Climate Action Plan," the framework for the refrigerant, aims to promote to confirm and approve more climate-friendly chemicals through the "Significant New Alternatives Policy."

According to the United States 'Clean Air Act', EPA issued a "Significant New Alternatives Policy" is entitled to evaluate alternatives for ozone-friendly chemicals and related technologies. The EPA intends to be on the list of "Significant New Alternatives Policy" under the extension, approval has released more new low "global warming potential" (GWP) refrigerants alternative chemicals to replace those serious ozone-depleting chemicals and other global warming caused by Freon products.

According refrigeration Express reporter, in addition to the recommended climate-friendly alternative refrigerants, EPA also intends to amend the substitute chemical emissions bans four kinds, because there is evidence that emissions of these chemicals, or processed and will not spread pose a threat to the environment.
