Chlorodifluoromethane CHClF2(R-22 or HCFC-22), a type of Freon.[6][7] Dichlorodifluoromethane CCl2F2(R-12 or CFC-12), the most commonly used Freon brand refrigerant prior to its ban in many countries in 1996 and total ban in 2010. 1,1,1,2-Tetrafluoroethane CF3CH2F (R-134a or HFC-134a), one of the main replacements for the formerly widespread R-12. Freon is a rade name formed by the Chemours Co.
Automotive Freon is R-12 (or the new R-132 and R-134). Central air freon is R-22. They are not compatible because of their different boiling points. R-22 is being phased out through the year 2010, but there is no standard replacement.
R-22
The most common for vehicles are R-12 and R134a freon.......... The most common for homes are R-22 and R-410A freon..........
"Freon" is DuPont's trademark for its CFC refrigerant products. R-22 is one of those refrigerants, so R-22 and Freon-22 are the same refrigerant.
