The mixing of R-134a with R-1234yf will change refrigerant pressure and may result in evaporator freeze-up on pressure control systems, reducing system airflow.15 Nov 2016
Is r134 the same as R1234yf?
R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The biggest difference between the two is that R1234yf is mildly flammable and does require special handling. Diagnosis of the air-conditioning system can be done in the same way as with R134a.20 Apr 2017
Is 1234yf oil compatible with 134a?
While R-1234yf oils are backwards compatible with R-134a systems, R-134a PAG oils are not compatible with R-1234yf systems.
Is R-134a compatible with R1234yf?
yes R1234yf Freon gas can be replaced by R134a; the newer systems were designed with this in mind so no, there will be no damage to the compressor but some time in the future doing so may become illegal. >>
Can you convert 134a to 1234yf?
It is illegal to convert an R12 or 134a system to 1234yf. The industry has no tests or published information to establish cooling performance, reliability, compatibility, or an assessment of chemical damage to a system's lubricant seals and hoses.20 Aug 2019
Can R1234yf be used to retrofit an R134a system?
Unlike when R12 was changed to R134a, you cannot retrofit to use R1234yf. The potential flammability of R1234yr has caused some European OEMs to choose R744 instead. R744 is carbon dioxide, so it is non-flammable.20 Apr 2017
Is R1234yf better than R134a?
Refrigerant R1234yf has a low global warming potential of 4, compared to 1430 for R134a, and has thermodynamic properties similar to R134a, making it a desirable choice for future automotive refrigerants. R1234yf has a significant potential to be a drop-in replacement for R134a in the near future.
