R-1234yf

1234yf is a zero ozone depleting refrigerant with very low global warming potential (GWP), developed to comply with the European F-Gas Directive, for the phase-out of refrigerants with high global warming potential in the Mobile Air Conditioning (MAC) sector. With a global warming potential of 4, the 1234yf easily complies with the EU MAC Directive. 1234yf has similar performance compared to HFC-134a and has the virtue of replacing HFC-134a in all applications where mild flammability is acceptable.

1234yf is slightly flammable (A2L), and requires minor changes in equipment design for use in direct expansion mobile air conditioning systems.

Applications:

– New automotive air conditioning equipment (MAC).

Additional information:

– The HFO-1234yf cannot be used for retrofitting existing equipment.

– HFO-1234yf is slightly flammable compared to HFC-134a and requires additional safety measures during implementation, use and service.

– The HFO-1234yf requires the use of specially designed recovery equipment, leak detectors and identifiers:

– Recovery and recovery/recovery/recycling equipment must comply with J2843, J2851 and/or VDA requirements.

– Leak detectors must comply with J2913 and/or VDA requirements.

– Refrigerant identifiers must comply with J2927 or J2912 and/or VDA requirements.

NOTES:

The F-Gas directive banned the use of refrigerants with an Atmospheric Warming Potential greater than 150 for new car models manufactured after 2011. Therefore, research focused on finding a gas with a very low greenhouse effect, but at the same time non-toxic and non-flammable (or low flammability) and this is how HFO (Hydro Fluoro Olefins) fluorinated hydrocarbons were born, which have a C = C double bond with an almost zero GWP.

HFOs are the 4th generation of fluorinated refrigerant gases and are currently the best answer to a market that wants products that are safe for users and the environment.
