HFO Sightings: Refrigerant Retrofits Becoming More Common in Supermarkets

Best practices help ensure supermarket transitions to low-GWP blends go smoothly

October 1, 2018

HFO blends are not drop-in refrigerants, and modifications usually have to be made to the equipment before they are used. However, following the guidelines from experts in the industry can help ensure a smooth transition.

Let’s Worry More About Refrigerant Leaks, Less About Metrics

When I first started writing about the HVACR industry more than 25 years ago, the term used to describe the harmful effects of refrigerant emissions in the atmosphere was ODP. After scientists discovered the hole in the ozone layer, they determined that it was caused by the chlorine in chemical compounds like CFCs, which were widely used in aerosols and refrigerants. They needed a measurement to describe the amount of ozone depletion caused by various substances, thus the term ODP was born.

The Chemours Co. has announced that the U.S. Environmental Protection Agency (EPA) through its Significant New Alternatives Policy (SNAP) program, has listed the low global-warming potential (GWP) refrigerant Opteon™ XP44 (R-452A) as acceptable for use in new and retrofit equipment for refrigerated transport and remote condensing units used in retail food refrigeration.

What’s Happening With R-134a?

Here are some alternatives to replace the venerable but high-GWP refrigerant

R-134a has a global-warming potential (GWP) of 1,430. This means it traps 1,430 times as much heat per kilogram as carbon dioxide does over a 100-year period. Because R-134a has such a high GWP, the U.S. Environmental Protection Agency (EPA) listed R-134a as an “unacceptable” refrigerant for certain refrigeration and air conditioning applications under its Significant New Alternatives Policy (SNAP) program.
