EPA GreenChill Offers Guide to Refrigeration Retrofits, Leak Prevention

The EPA GreenChill organization is a national champion for reduced refrigerant leaks in supermarkets across the U.S. This guide was issued in August 2011, and includes rationale for HFC refrigerant retrofits, best practices for transitioning to HFC-substitute chemicals and system end-of-service-life options, and refrigerant recovery and recycling.

The Environmental Protection Agency GreenChill Advanced Refrigeration Partnership is a group of refrigeration industry manufacturers and supermarkets striving to achieve reductions in refrigerant leaks in supermarkets across the U.S.

In August of 2011, GreenChill issued a Best Practices Guideline for Commercial Refrigeration Retrofits. The guide includes rationale for HFC refrigerant retrofits, best practices for transitioning to HFC-substitute chemicals and system end-of-service-life options, and refrigerant recovery and recycling. It also includes updated information on the phaseout of HCFC-22 (R22); information on ICOR International's R422B and R422C; Honeywell performance data; case histories; and a checklist for R407F. It includes Arkema performance data on R407A, and DuPont information on R438A.

Other major headings include:
conversion guidelines for HFC substitute chemicals;
differences in retrofit procedures for substitute chemicals;
end-of-life options for refrigerants and equipment;
best practices for refrigerant recovery, recycling, reclamation, and destruction.

The guide — which was developed with the help of many knowledgeable refrigeration industry professionals— can be found by clicking on this link to GreenChill Retrofit Guidelines.
