HFO-1234yf, 2,3,3,3-Tetrafluoropropene

 R1234yf refrigerant gauges for service.HFO-1234yf recharge services.

Refrigerant HFO-1234yf,is a highly efficient, safe and effective replacement for HFC-134a.R1234yf was the subject of comprehensive testing conducted by an ASE International Cooperative Research Project from 2007 to 2009.That project, which was sponsored by 15 global automakers,major suppliers and 18 international, independent research institutes, concluded that 1234yf is safe for use in automobile applications.

The European Union’s Mobile Air Conditioning (MAC) directive requires that refrigerants in all new type vehicles sold in Europe after January 1,2013 have a global-warming potential (GWP) below 150 and that all cars sold after 2017 meet the lower GWP requirement.

The US.EPA has issued regulations that call for r134a to be phased out of domestic new car production by 2021.R134a refrigerant will still be allowed for certain export vehicles, but only until 2025, after that, all new vehicles will have to use r1234yf refrigerant. R-134a production will continue for servicing older vehicles.

Differences between R-134a and 1234yf Freon.

HFO-1234yf has a GWP of 4 and reduces global warming impact by 99.7 % compared with HFC-134a.The biggest difference is r1234yf refrigerant flammability rating, which means it is mildly flammable and the cost that shops will be paying from suppliers. SAE concluded it was 20,000 times more likely for a person to die in a plane crash than exposed to a vehicle fire caused by a leak and ignition of HFO-1234yf.

Compared with r134a, considerable upgrades to component quality and robustness, as well, as compliance with a number of new SAE standards, have been engineered into r1234yf systems. The systems are designed to prevent potential refrigerant leakage into the cabin. The PAG oil is specific for 1234yf Freon and shops will need some new tools to work in compliance with new SAE standards, like new leak detectors and recovery recycling machines.

SAE standards for quality and safety.

SAE International also known as the Society of Automotive Engineers is an independent, global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries.
