Résumé

In a world that is focused on improving the environment and becoming a greener and more efficient planet the importance for change and development is ever increasing. To ensure that we are all doing our part to reduce global warming (GWP) and increase our performance and efficacy, we have developed refrigerant blends with R-744 as the principal component. While these blends are formulated to maximise performance whilst maintaining a low GWP, they are blends and may suffer from composition shifting if not properly handled in application. Fractionation studies with various formulations were carried out to ensure these blends maintain a non-flammable rating in application even as the composition in the working system may shift. Using experimental and modelled data to validate the opinion that when LFR3 is used in a system under different conditions it is unlikely to ever achieve a flammable scenario.
