Hi,

All the current refrigerants are classified in these three categories.

CFC refrigerants	HCFC refrigerants	HFC refrigerants
The basic composition is Carbon, Fluorine, Oxygen	The basic composition is Hydrogen, Carbon, Fluorine, Oxygen	The basic composition is Hydrogen, Fluorine, Oxygen
The CFC refrigerant is now totally banned from use or production within all countries covered by the Montreal Protocol	The HCFC gases are to be banned from Virgin use from Jan 2010. The general phase out shall be complete by 2015 unless the dates are brought forward.	The HFC gases are used extensively in everyday RAC systems. There is no current ban upon these gases but a responsible use and equipment inspection are mandatory under the "F gas" regulations.
The CFC refrigerants such as the once popular R12 has the highest ozone depleting rating (1) and is also a green house gas	The HCFC refrigerants such as the popular R22 has a potential to damage ozone (rating 0.05) and is also a green house gas	The HFC refrigerants have no ozone depletion potential but do act as a green house gas.
It is unlikely that many systems exist in operation with this refrigerant	There are still many systems utilizing these refrigerants	They are the currently used refrigerants.
