The Experimental Comparison of R1234yf and R134a

Product Description |
|
HFOs are unsaturated organic molecules having carbon, hydrogen and fluorine. They are unstable molecules with low GWP and small atmospheric lifetime due to the pre-sence of double bond. HFOs differ from traditional HFCs by being derivatives of alkenes rather than alkanes. There are two types of refrigerants in this class: R1234yf refrigerant (2,3,3,3-tetrafluoropropene) and R1234ze refrigerant (trans 1,3,3,3-tetrafluoropropene) HFOs, R1234yf refrigerants and R1234ze refrigerants are now considered as the most promising fourth-generation refrigerants.
