R134a and R1234yf are two different types of refrigerants commonly used in automotive air conditioning systems. Here are the main differences between the two: Chemical Composition: R134a, also known as Tetrafluoroethane, is a hydrofluorocarbon (HFC) refrigerant with a chemical formula of CH2FCF3. On the other hand, R1234yf, also known as 2,3,3,3-Tetrafluoropropene, is a hydrofluoroolefin (HFO) refrigerant with a chemical formula of CH2=CFCF3. Global Warming Potential (GWP): GWP is a measure of the greenhouse gas potential of a substance compared to carbon dioxide (CO2). R134a has a relatively high GWP of 1,430, which means it has a significant impact on global warming when released into the atmosphere. In contrast, R1234yf has a much lower GWP of 1, which makes it more environmentally friendly. Environmental Regulations: Due to concerns about climate change and the high GWP of R134a, many countries and regions have introduced regulations to phase out its use in new vehicles.
