How do low-GWP HFOs, HFCs and blends stack up against so-called “natural” refrigerants? An Expert’s Take on So-Called “Naturals” takes a deep dive into the world of refrigerants with unique perspectives from refrigeration expert Dr. Richard Powell. Here’s a preview: 

An Expert’s Take on So-Called “Naturals”

globalFACT: What can [this interview] teach us about the future of refrigerants?

Dr. Powell: Simply put: no refrigerant can be dismissed outright. Even the most ardent promoters of so-called “natural” refrigerants are willing to countenance refrigerants with GWPs up to 250 where TEWI values suggest this is warranted. I interpret this as a recognition that “natural” refrigerants will not be able to meet the cooling industry’s needs. In other words, the HFO refrigerants have a future because the “natural” refrigerants have problems.

globalFACT: What guidance would you offer end users in choosing between so-called “naturals” against other refrigerant options?

Dr. Powell: “Natural” refrigerants might be considered as the “silver bullet” providing an obvious answer to the higher-GWP HFCs. Hopefully my answers today have helped debunk that myth.

Humanity needs cooling systems and thus refrigerants for its health and well-being, but without compromising the safety of the users or the global environment. HFOs can do this. Hazardous “natural” refrigerants can’t.
