R450A (Solstice N13) is a blend of HFC and HFO refrigerants designed to retrofit R134a in medium temperature applications. R450A offers similar performance to R134a. Importantly R450A has a lower GWP of 601 compared to R134a?s GWP of 1430. It is non-toxic and non-flammable meeting the highest A1/A1 classification.
HFC's are a type of synthetic greenhouse gas (SGG) having global warming potential. To reduce emissions of these gases globally a HFC phase-down under the Montreal Protocol was agreed in Kigali, Rwanda, in October 2016. Commencing in 2018, the Australian phase down will conclude in 2036 reaching an 85% reduction target.
Longer term the use of HFO A2L refrigerants such as R1234yf and 1234ze are likely to replace R134a in new equipment.
