It’s Critical During Commercial Refrigeration Retrofits
EDITOR’S NOTE: The following article was prepared by GreenChill, the Advanced Refrigeration Partnership with the U.S. Environmental Protection Agency (EPA).
To meet our obligations under the Montreal Protocol, the United States is phasing out production of HCFC-22, an ozone depleting substance. Many food retailers are adapting to future R-22 supply constraints by transitioning away from this refrigerant. Retrofitting R-22-based commercial refrigeration systems to use substitute refrigerants is one transition option. Because most of these substitute refrigerants are potent greenhouse gases, it is important that food retailers use the retrofitting process as an opportunity to tighten system leaks.
