is 1234yf compatible with r134a

  • Relax - R1234yf Is Not The End Of The World

    R134a may take up to 10 years to breakdown into a non-greenhouse gas. Twenty-five years ago, this was seen as considerable improvement over the 100-year-plus lifespan of R12. But R1234yf is a further advancement over R134a, as it takes only three to four years to break down in the upper atmosphere.

    8/29/2018· If you were to put R1234yf in a system designed for R134a, it looks like you'd end up with about a 10% loss of cooling capacity, but putting R134a into a R1234yf system would be a wash. It appears R1234yf oil is compatible with R134a (but not vice-versa), so shouldn't be a problem there.

    R-1234yf requires a compatible oil for effective use. (Some PAG, PVE, and POE oils are also backwards compatible with R-134a but not vice versa.) R-134a and R-1234yf should not be mixed. In some cases, mixing can be illegal. R-1234yf is very corrosive. Only clean, properly specified lubricants are able to protect the system.

  • R1234yf Refrigerant | ARC Industry Site

    Is R1234yf compatible with existing R134a equipment? No. The R1234yf system refrigerant circuit is accessed using service couplers that are a different size to those of a R134a system. The service coupler hose connection also has a left-hand thread that requires a matching hose for connection. Hence the need for an R1234yf gauge set.

  • R1234yf and Lubricants: An update about recent developments

    Recent studies (Spatz 2009, Bobbo et al. 2011) indicate a rather different behaviour of R1234yf in comparison with R134a in PAG lubricants originally developed for R134a. In general R1234yf shows lower solubility than R134a in the same lubricant, under the same thermodynamic conditions and displays larger immiscible regions sometimes with the ...
