DOE & EPA, What are the Ties to Refrigerants?

How Commercial Refrigerants Are Impacted by DOE & EPA

July, 24th, 2019


The Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) have been evaluating energy use and environmental trends for many years. Although legislative organization began nearly a dozen years ago, trends have largely remained consistent. R-22, or HCFC-22, along with other refrigerants, is being phased out because of its impact on the environment, contributing to the depletion of the ozone layer.


Shortly after the current president took office in 2017, the DOE established new energy conservation standards for walk-in coolers and freezers. Around the same time, the EPA listed several refrigerants as acceptable in certain applications, refrigerants with medium Global Warming Potential (GWP) values. The GWP was developed so that various gases could be compared to determine their impact on global warming. Understandably, the DOE and EPA want to reduce the negative impact of refrigerants on the environment to the greatest extent possible.


SNAP Determination 33 outlines the accepted refrigerants which include R-134A, R-407H, R-442A, R-448A, R-449A, R-449B, R-452A, R-452C, R-453A, R-458A and R-513A. All of these refrigerants have a medium GWP value (630-2,220) and are classified as A1 (non-flammable, non-toxic) according to American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) standards, and are suitable for a wide range of end uses.
