A refrigerant composition consisting only of the components as claimed in .16. A refrigerant composition as claimed in having a Global Warming Potential greater than 1000. This invention relates to refrigerant compositions.Chlorofluorocarbons (CFCs) such as CFC12 and CFC502 and hydrochlorofluorocarbons (HFCs) such as HCFC22 migrate to the stratosphere where they are broken down by ultra violet light producing chlorine atoms that destroy the ozone layer. These Ozone Depleting Substances (ODS) are in the process of being replaced by non-ozone depleting alternatives such as hydrofluorocarbons (HFCs) which are non-flammable, efficient and of low toxicity. In certain applications, particularly but not specifically related to low temperature refrigeration systems often used in supermarkets, R502 was the main refrigerant of choice due largely to its lower discharge temperature compared to R22. As a consequence of the global environmental agreement embodied in the Montreal Protocol, R502 has been banned. R502 has been largely replaced by the HFCs R404A and R507. However R404A and R507, while being excellent refrigerants in terms of energy efficiency, non-flammability, low toxicity and thermodynamic properties, nevertheless have GWPs which are at the high end of the commonly used HFCs.It is an object of this invention to provide refrigerant compositions which have Global Warming Potentials (GWP) exceeding 1,000 but less than 1600 on an Integrated Time Horizon (ITH) of 100 years. In this specification the numerical value for Global Warming Potential (GWP) refer to an Integrated Time Horizon (ITH) of 100 years as contained in the Inter-Governmental Panel on Climate Change Fourth Assessment Report (AR4) and have no adverse effect on stratospheric ozone. This invention relates to blends which are particularly, but not ...
