R1234yf : Introduction
2,3,3,3-Tetrafluoropropene, or HFO-1234yf, is a hydrofluoroolefin with the formula CH2=CFCF3. It has been proposed as a replacement for R-134a as a refrigerant in automobile air conditioners.HFO-1234yf is the first in a new class of refrigerants acquiring a global warming potential (GWP) rating one 335th that of R-134a (and only 4 times higher than carbon dioxide, which can also be used as a refrigerant but which has properties significantly different from those of R134A, especially requiring operation at around 5 times higher pressure) and an atmospheric lifetime of about 400 times shorter. It was developed to meet the European directive 2006/40/EC that went into effect in 2011 requiring that all new car platforms for sale in Europe use a refrigerant in its AC system with a GWP below 150.
