R-1234yf

R-1234yf is a low-GWP refrigerant valued for its eco-friendly properties and efficient cooling performance. This mildly flammable refrigerant is designed to meet global standards for reduced greenhouse gas emissions. Some example applications of
R-1234yf include:

R1234YF cylinder

Automotive Air Conditioning

R-1234yf has replaced R-134a in most modern vehicles to comply with environmental directives, providing effective cooling in passenger cars and light-duty trucks.

Regulatory Compliance

Mandated for use in the European Union and widely adopted in the United States, R-1234yf meets regulations requiring refrigerants with a global warming potential (GWP) of less than 150.

Environmental impact

While R-1234yf significantly reduces environmental harm with a GWP of less than 1 compared to R-134a's GWP of 1,430, it degrades into trifluoroacetic acid (TFA) in the atmosphere. This compound can persist in ecosystems, requiring careful consideration of its long-term environmental effects. Transitioning to even more sustainable refrigerants may be necessary in the future.
