What is CFC and HCFC?
CFC : Chloro-Fluoro-Carbon
High ODP( ozone depletion potential ) chemical compound, including chlorine. (ODP:0.6-1.0)
For example : R12 (for refrigerator and car air-conditioner)
Low ODP chemical compound, including chlorine and hydrogen. (ODP:0.02-01)
HCFC : Hydro-Chloro-Fluoro-Carbon
For example : R22 (for air-conditioner)
R134a (for Car air conditioner)
