Refrigerators do not produce CFC. Old equipment contains these materials as they were the refrigerant of choice before the Montreal Protocol. The old equipment lost the CFCs to the atmosphere due to leaks and gasket failure.

What effect do CFCs have on the Earth's stratosphere?
CFCs (Chlorofluorocarbons)What type of substance is it?CFCs are a class of man-made chemicals, generally non-toxic, non-flammable, chemically unreactive, colourless liquids or gases that evaporate easily. They are a group of ozone depleting substances. They damage the Earth's ozone layer, which protects the earth's surface from harmful ultra-violet radiation. CFCs are also powerful greenhouse gases which contribute to global warming.How is it released?Release to the atmosphere is primarily from CFC-containing aerosols, refrigeration equipment and some foams. There are no natural sources of CFCs.
Is there a tree which can absorb CFCs?
no
How does chlorofluorocarbon rise to the stratosphere?
CFC is lighter than air just like hot air. Once freed, it rises readily to the upper atmosphere at the level of the ozone layer where it can react with the extra atom of oxygen in the ozone.
Are all CFCs greenhouse gasses?
Yes, even though they are primarily harmful because of their effect on ozone depletion. CFCs have both effects. The two effects are different. The ozone depletion is worse.
Is there an alternative to cfcs?
yes, flourocarbons and isobutane
How do you CFCs illustrate that technical knowledge can be a double edged sword?
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
What CFCs are the main cause of what?
CFC's used in refrigeration are main cause of ozone depletion. This refers to the destruction of ozone.
What can companies that now produce CFCs do to replace money lost when CFCs are banned?
Make something else BUT this time check that the products they are making are not harmful. They aught also to pay towards the environmental harm that CFCs have caused.
How do ice houses produce ice?
With big refrigeration units.

What is the net refrigeration effect in the refrigeration cycle?
The quantity of heat that each pound of refrigerant absorbs from the refrigerated space to produce useful cooling.
Does a refrigerator have a effect on the world?
The best answer is 'yes' as the development of refrigeration has led to many discoveries and better health of nations. An example of refrigeration having a negative effect on the world was the making of chlorofluorocarbons in the early 20th century. These CFCs were used as a cooling substance, which was the main way refrigerators kept things cold. The making of these CFCs and the releasing of CFCs back into the atmosphere has led to the main destruction of the ozone layer, the layer around Earth that protects Earth from harmful rays from the sun. While one refrigerator may not effect the entire world (unless you are Indiana Jones in the 4th movie), refrigeration has made an effect on the planet.
Can rain demolish CFCs?
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
What does the Refrigeration and Heating Equipment industry produce?
This category includes establishments primarily engaged in the manufacture of commercial or industrial refrigeration equipment or domestic, commercial, or industrial air-conditioning units.
Are CFCs highly toxic?
Chlorofluorocarbons (CFCs) are non-toxic.
What substitutes for CFCs came into being after scientists discovered that CFCs were harming the atmosphere?
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
How are cfcs released?
CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.
