What are HFO’s?

HFO refrigerants, or Hydrofluro-Olefins, are a new class of refrigerants that have a much lessened global warming potential than it’s HCFC alternatives. One example being the 134a alternative, 1234YF, which is 335 times lower on the global warming potential scale and only four times higher than standard carbon dioxide.

HFOs are the refrigerant of the future… for now. I say for now because we’ve been through this before. A new refrigerant is introduced and then something is found to be harmful in that chemical and the refrigerant is replaced with a new and better line. Maybe HFOs are the perfect refrigerant, but I have a feeling we’ll be going through this again and sooner rather than later. Let’s keep everyone on their toes…
