R22 is a HCFC refrigerant (comprised of hydrogen, chlorine, fluorine, and carbon)
and is the most common refrig erant used in the world today. T he air conditioning
industry is in the process of moving to HFC refrigerants
(comprised of hydrogen, fl uorine and carbon) as they have no chlorine c ontent
a nd zero O zone Depleti on Potenti a l (O DP).
