Editor's Notes
- HFO = hydro-fluoro-carbon – meaning the molecule is composed of hydrogen, fluorine and carbon. Note that like HFCs, they contain no chlorine, and therefore also have zero ozone depletion potential. Note also that like HFCs they contain fluorine, and like HFCs, this fluorine is what delivers the unique and desireable balance of properties. So what makes the HFOs different than the HFCs? Like HFCs they are stable in an operating system. However unlike HFCs, when exposed to the atmosphere – for example under a leak situation – they are much less stable and break down more easily, resulting in a much lower GWP. Also – testing is confirming that these HFOs can deliver efficient performance similar to the HFCs they are designed to replace. I’ll be sharing more about this in a few minutes.
