HFC refrigerants, or hydrofluorocarbons, are considered ozone-friendly primarily because they do not contain chlorine, which is the element responsible for ozone layer depletion. This characteristic makes them a preferred choice over older refrigerants like CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons), both of which are notorious for their high ozone depletion potential.

Choosing HFCs, manufacturers sought to provide a solution that would help protect the stratospheric ozone layer while maintaining effective refrigeration and air conditioning performance. As HFCs do not break down ozone, they are compliant with various regulations that aim to phase out substances harmful to the ozone layer.

Although there are environmental concerns surrounding the global warming potential of HFCs, their relationship with ozone depletion is distinctly favorable, highlighting their role as alternatives to more harmful substances. This understanding aligns with current regulations under the Montreal Protocol, which emphasizes the need for ozone-friendly materials in the field of refrigeration and air conditioning.
