Résumé

Refrigerant choices for refrigeration systems are undergoing significant change. The phaseout of R-22 is well into its final few years. Severely restricted now, production and importation of new R-22 in the U.S. will cease as of 2020. EPA Significant New Alternatives Policy (SNAP) Rule 20, issued in July 2015, also sets a time line for delisting R-404A, R-507, and others as acceptable alternatives for many commercial refrigeration applications.1 Some of the first delistings concerning system retrofits took effect July 20, 2016. EPA has also approved (or SNAP listed) several alternative HFC and HFO-blend refrigerants that may be used to retrofit existing systems and for new systems.
