HFO-1234yf is a type of refrigerant used primarily in automotive air conditioning systems. It is a hydrofluoroolefin, which means it contains hydrogen, fluorine, and carbon. This refrigerant was developed as a more environmentally friendly alternative to HFC-134a, which has a higher global warming potential. One of the key benefits of HFO-1234yf is its low global warming potential, making it a better choice for reducing greenhouse gas emissions. It is also non-ozone-depleting, which means it does not harm the ozone layer. As a result, many countries are transitioning to HFO-1234yf to comply with environmental regulations.
