HFO stands for hydrofluoro olefin. Opteon™ YF (HFO-1234yf) is a low global warming potential (GWP) refrigerant for use in automotive air-conditioning systems. Opteon™ YF (HFO-1234yf) has a chemical structure of CF3CF= CH2 2,3,3,3-tetrafluoropropene.

Opteon™ YF (HFO-1234yf) use in automotive air conditioning-

Potential exists for direct substitution of Opteon™ YF (HFO-1234yf) into existing HFC-134a automotive air-conditioning systems with minimal modification. Opteon™ YF (HFO-1234yf) also has the potential as a retrofit refrigerant in existing HFC-134a systems.

Life Cycle results show that Opteon™ YF (HFO-1234yf) has improved performance as compared with HFC-134a. It has very low direct contribution to climate change and lower indirect contribution to climate change versus the current refrigerant HFC-134a. With further efficiency improvements, indirect contribution to climate change can be reduced further.
