1234yf

1234yf is a refrigerant with zero ozone layer depletion and very low global warming potential (GWP), developed to comply with the European F-Gas Directive for the progressive elimination of refrigerants with a high potential for global warming in the Mobile Air Conditioning (MAC) sector. With a global warming potential of 4, 1234yf easily complies with the EU MAC Directive. 1234yf features similar operational functions to HFC-134a and has the ability to replace HFC-134a in any applications that tolerate slight flammability.

1234yf is slightly flammable (A2L), and requires small changes to the equipment design for it to be used in direct expansion mobile air conditioning systems.

Applications:

· New automobile air conditioning equipment (MAC). 

Additional information:

· HFO-1234yf cannot be used in the retrofit of existing equipment.

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

· HFO-1234yf requires the use of specifically designed equipment for recovery, detection of leaks and identifiers:

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

- Leakage detectors must comply with J2913 and/or VDA requirements.

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

APPLICATIONS

  • High temperatures
  • new Installations

FEATURES

 Does not damage the ozone layer, ODP = 0

· Working pressures similar to those of R-134a.

· Thermically stable in extreme conditions found in equipment (MAC).

· Cooling capacity equivalent to that of R-134a.

· Energy efficiency higher or equivalent to that of R-134a.

· Global warming potential (GWP) = 4

· Boiling point at 1.013 bar (ºC): -29.55

· Saturated vapour density at -29.55ºC (kg/m3): 5.98  

· UN nº: 3161

· Safety classification: A2L. Low toxicity and slightly flammable.

NOTES

The F-Gas directive prohibits the use of refrigerants with a Global Warming Potential higher than 150 for new automobile models manufactured from 2011 onwards. As a consequence, research focussed on finding a gas with a very low greenhouse gas effect, but at the same time non-toxic and nonflammable (or only slightly flammable) and out of this came the HFO fluorohydrocarbons (Hydrofluoroolefins) that have a C = C double bond with a virtually negligible PCA.

HFOs are 4th generation fluorinated refrigerant gases and are currently the best solution for a market that demands products that are safe for the users and the environment.
