R-1234yf is also a component of zeotropic refrigerant blend R-454B. HFO-1234yf has a GWP less than carbon dioxide, [4] [2] itself 1,430 times less potent than R-134a. [5] For this reason, 2,3,3,3‑tetrafluoropropene is the pre-eminent replacement for R-134a in vehicular air conditioners. As of 2022, 90% of new U.S. vehicles are estimated to ...
