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.
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.
never mix these freons together---- very dangerous
Centrifugal Compressor and Rotary Compressor is preferred with refrigerant R-113.
