Description

Phase-Down of HFC Refrigerants

and the impact on

refrigeration and air conditioning

On October 15th, 2016, in Kigali, Rwanda, nearly 200 nations, including Canada, adopted an Amendment to rhe 1989 Montreal Protocol on Substances to Deplete the Ozone Layer. In signing the Amendment, the nations agreed to phase-down the use of hydrofluorocarbons (HFCs) (e.g. R-134A: 1,1,1,2-tetrafluoroethane), which are used predominantly in refrigeration, air conditioning, and foam blowing applications. HFCs are greenhouse gases that can be hundreds to thousands of times more powerful than carbon dioxide, the predominant greenhouse gas. HFCs were developed to replace CFCs (e.g. R-12: CClF2) and HCFCs (e.g. R-22: CHClF2), which are now being phased down under the 1989 Montreal Protocol.

Although not widely recognized, the invention of CFC refrigerants in the first half of the 20th century was a disruptive technology that changed the history of the world.

Can we invent a simple replacement for CFCs, HCFCs and HFCs in existing refrigeration and air conditioning systems? As an alternative, can we re-engineer our cooling requirements, or new refrigeration equipment that meets these requirements?
