R-22 is the refrigerant that contains CFC (chlorofluorocarbon). R-134a does not contain CFCs but is considered an HFC (hydrofluorocarbon) refrigerant. R-500 contains a mixture of CFC-12 and CFC-22. R-123 is a halocarbon refrigerant but does not contain CFCs specifically.
R 500
R-12 freon and 500 viscosity oil.........
When r-500 is recovered from an appliance, it is a refrigerant that is being removed and collected for proper disposal or recycling. r-500 is a blend of R12 and R152a, both of which are ozone-depleting substances, so the recovery process is necessary to prevent environmental harm.
r-12
R 12 refrigerant.
what will replace R 134 refrigerant
It's a CFC refrigerant.
The 1995 Mercedes-Benz S500 uses R-134a refrigerant as its air conditioning refrigerant. This was a common replacement for the older R-12 (Freon) due to environmental regulations. If you are servicing the AC system, ensure that it is compatible with R-134a to avoid any issues.
R-500 and R-22 refrigerants do not use the same oil. R-22 typically uses mineral oil or alkylbenzene oil, while R-500, which is a blend of R-12 and R-22, generally requires a different type of oil, such as a synthetic lubricant. It's important to use the correct oil for each refrigerant to ensure optimal system performance and avoid compatibility issues.
R-134a is the only refrigerant approved by the automotive industry. It requires conversion to be used in an R-12 system.
The R in R-134a stands for refrigerant.
