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.
