Freon is or what is known (Alkruvrukopon CFC) organic compounds chemically, a non-flammable
gas, it compounds (HCFCs) and also containing hydrogen. A gas used in air conditioners and cooling of the car and buildings. The gas used in the home refrigerator interpreters gas being non-toxic and does not cause chemical reactions and does not cause any erosion of the structures of refrigerators, the same user in your home air conditioner, and central, and also air the car. And used on a wider scale in the solvent, and also in their own applications to the atmosphere, as well as ice creams, medical and commissary, and various medical sterilization equipment, electronic equipment sensitive, rarely we find any industry or free use Alfrionat application. It has been invented at the beginning of the twentieth century, as a substitute for toxic gases that were used before that date in cooling. The use of this gas has proven to be detrimental to the ozone layer, which leads to significant damage to them, and their depletion also, therefore, according to the agreement (Montreal), works to stop the use, processing and manufacturing of compounds. It has also shown that many cases of death have gotten a result inhaled in large quantities.

The compounds (kV k) used: Freon R11a, which is a: (tri chlorine, fluorine and mono, and methane), used in the plastic insulation, and also in the home refrigerator. Freon R12a, which is a: (a binary chlorine, fluorine, and a single-methane), used in large-capacity air-conditioners, and transportation. Freon R134a, which is a: (tri chlorine, fluorine, and ethane), used as a substitute for R122, due to the improved effectiveness.
