If hydrofluorocarbons (HFCs) are to have long-term viability, the low-global warming potential (GWP) versions will have to separate themselves from high-GWP types. And the survivors will have to play their part in energy efficiencies, especially in commercial buildings.
CO2 as a refrigerant has been a part of the refrigeration landscape for close to a decade. The most anticipated next step was running CO2 as a standalone refrigerant in a system, which is being done in Europe in more and larger applications. Finally, the approach crossed the Atlantic.
This article is the second of a two-part series in response to the question: “Should I choose CO2 (R-744) for my refrigeration system?” It was prepared by engineers with M&M Refrigeration of Federalsburg, Maryland.
This story was prepared by Danfoss and brings readers up to date on developments in Europe concerning HFC refrigerants. While what happens in Europe does not automatically reflect what will happen stateside, it would be wise for contractors in the United States and Canada to monitor developments overseas.
Company Says Rule Would Have Significant Impact on Equipment Used for Retail Food Refrigeration
August 19, 2014
Emerson Climate Technologies announced that it is preparing an industry communication to the U.S. Environmental Protection Agency’s (EPA’s) recent notice of proposed rulemaking (NOPR) that would delist some refrigerants commonly used in supermarkets and commercial refrigeration equipment.
