CFC, HCFC or HFC...?

Refrigerants are generally classified into one of the above three substances. Below is a brief explanation of each, to help you understand the differences...

CFC refrigerants

These are substances containing CARBON, FLORINE and CHLORINE chemicals. The CFC refrigerant is now totally banned from use or production within all countries covered by the Montreal Protocol. The CFC refrigerants such as the once popular R12 has the highest ozone depleting rating (1) and is also a green house gas. It is unlikely that many systems exist in operation with this refrigerant...

HCFC refrigerants

These are substances containing HYDROGEN, CARBON, FLORINE and CHLORINE chemicals. 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 HCFC refrigerants such as the popular R22 has a potential to damage ozone (rating 0.05) and is also a green house gas.There are still many systems utilising these refrigerants...

HFC refrigerants

These are substances containing HYDROGEN, FLORINE and CARBON chemicals. The HFC gases are used extensively in every day RAC systems. There is no current ban upon these gases but responsible use and equipment inspections is mandatory under the "F gas" regulations. The HFC refrigerants have no ozone depletion potential, but do act as a green house gas.

Ozone depletion

Ozone depletion or ODS is the decay of the protecting ozone layer that filters out harmfull UV light. An ozone depleting substance can remain in the stratosphere for long periods, causing holes in the layer and allowing harmful UV rays to reach the earths surface.

Green house effect (Global warming)

The green house effect as the name suggests, relates to the warming of the earths surface temperatures. This upsets the balance in the earths Eco systems. A green house gas has the potential to form a layer of gas in the upper stratosphere. These gases reflect the solar heat bounced off the earths surface back to surface level, rather than out through the stratosphere.The effect causes a rise in temperature as within a greenhouse...
