	freon (Site not responding. Last check: 2007-10-07)
		Prior to their implication as a major contributor to ozone depletion (and a minor contributor to the greenhouse effect), freons were also used as aerosol propellants and to foam up polymer materials.
		Freon was developed as a safer alternative to toxic gases such as, ammonia (NH methyl chloride (CH Cl), and sulfur dioxide (SO), that were used as refrigerants prior to the discovery of freon.
		Freon in copper tubing open to the enviroment can turn into phosgene gas after coming in contact with extreme heat, such as, while brazing or in a [fire]] situation.

	Haloalkane - Wikipedia, the free encyclopedia
		Freon is a trade name for a group of chlorofluorocarbons used primarily as a refrigerant.
		There is concern that halons are being broken down in the atmosphere to bromine, which reacts with ozone, leading to depletion of the ozone layer (this is similar to the case of chlorofluorocarbons such as freon).
		Freon in copper tubing open to the environment can turn into phosgene gas after coming in contact with extreme heat, such as while brazing or in a fire situation.

	Freon - NIEHS Alphabetical Listing of Health Topics
		Answer: "Freon" is not a chemical per se, "Freon" is actually a trade name that describes a whole class of chemicals used in refrigeration.
		Most of the chemicals included under the trade name of "Freon" are known as "chlorofluorocarbons." This means that their chemical structure is made up of the main chemical building blocks of carbon and hydrogen, but they also include chlorine and fluorine as well.
		This means that breathing low concentrations of freon from a leaking refrigerator or air conditioner over a long period of time is unlikely to have a cumulative effect, and thus few, if any, long term health effects.

	Freon In Cigarettes And The Fluoride Breakdown Connection
		Since we got into some of the freon decomposition effects with temperature or radiation, which means it is not inert, you might like to take note of its use in cigarettes.
		One last thing that few folks realize is that the largest user of freon in the US were the Oak Ridge gas diffsusion plants, which used train car loads of it to cool the thousands of stages of the diffusion process...which used more electric power than in consumed by NY city.
		Freon is used as a coolant in air conditioning and refrigeration systems and as an aerosol propellant.

	Freon Facts
		Some of the more common misconceptions are, that eventually, more Freon needs to be added to the refrigerator, odors in the refrigerator are caused by a leak of this gas, and if it does leak inside the cabinet the food stored there is now contaminated.
		In 1931 the inventor of Freon, Thomas Midgley made a public demonstration that it was harmless by filling his lungs with the gas then blowing out a candle.
		The family of Freon type gasses work their way higher and higher into the atmosphere due to kinetic reaction with the other molecules in the air.

		The liquid Freon is sent to a strainer/dehydrator/tank (drier) where it is filtered and passed over beads of a drying agent to remove any water.
		To recharge the system, attach a Freon supply to the center line of the manifold/gage set, the low pressure manifold line must be connected to the low pressure refrigeration line and the high pressure manifold line must be connected to the high pressure refrigeration line.
		Freon will evaporate rapidly from the Freon supply as it is drawn in to the low pressure side of the refrigeration system.

		Effects of freon 113 on human health and the environment depend on how much freon 113 is present and the length and frequency of exposure.
		Freon 113 is not likely to cause adverse human health effects following repeat exposure to smaller amounts of the chemical over long periods of time.
		Freon 113 is not likely to cause immediate environmental harm at levels normally found in the environment.

	Auto Air Conditioning Troubleshooting
		This Freon is a gas and liquid combination that is compressed and circulated throughout the air conditioning system.
		The compressed Freon is pushed through the system under pressure and is passed through different sized metal and rubber hoses and a special valve called an expansion valve that cause the gas to expand and contract.
		This heat is removed by the Freon with the help of the AC condenser located at the front of the car (usually in front of the radiator).

	1930: Freon®
		Freon® made possible widespread use of refrigerators and air conditioners and served as propellant in aerosol sprays of all types.
		Freon® (chlorofluorocarbon or CFC) was developed by two General Motors scientists and manufactured by DuPont at Deepwater, New Jersey, beginning in 1930.
		Non-CFC substitutes for Freon® - Suva® refrigerants and Dymel® propellants –; were commercialized in 1990.

		Freon[frE´on] Pronunciation Key [trade name], any one of a special class of chemical compounds that are used as refrigerants, aerosol propellants, and solvents.
		Every Freon contains at least some fluorine in its molecule, and most contain chlorine or bromine as well.
		Freons are generally colorless, odorless, nontoxic, noncorrosive, nonflammable, and chemically unreactive.

	SS Archives --August 14, 1997
		The perceived danger of Freon led Congress to outlaw the U.S. production of Freon after December 1995; automakers have switched over to a more environmentally friendly refrigerant, called "R-134a," on their 1995 and newer models.
		Unlike Freon, R-134a is environmentally friendly in that it doesn't harm the ozone layer.
		Having your old Freon system rebuilt for about what you'd pay for the retrofit kit and betting that there'll be ample refrigerant in the future doesn't seem especially prudent.

		In the meanwhile, federal taxes on the remaining stocks of Freon, combined with the effects of scarcity, have driven per-pound costs of the stuff from around $2 to more than $40.
		What's more, Freon is no longer legally available to private individuals; one must be a certified air-conditioning mechanic with all the necessary EPA say-sos before one may lawfully buy R-12.
		But in a few short years, even certified technicians may not be able to get their hands on any Freon; supplies are rapidly dwindling and import prohibitions prevent repair shops from bringing Freon into the U.S. from countries where it is still legal to produce it.

	WATER COOLANT LOOP SYSTEM
		When a Freon coolant pump is operating, Freon is routed in parallel through the three fuel cell heat exchangers and the midbody cold plate network to cool electronic avionics units.
		The Freon flows from the hydraulic fluid heat exchanger to the radiators, which are bypassed through a bypass valve during ascent and entry because the payload bay doors are closed.
		The indicator indicates byp when the bypass valve in that Freon coolant loop is in the bypass position, barberpole when the motor-operated bypass valve is in transit and rad when the bypass valve is in the radiator flow position.

	Air Conditioning
		We have been faithfully collecting the gaseous Freon in the can outside the window, and since we have been cooling it by blowing outside air across the can we now have a tank of liquid Freon outside the house, and it is back to a reasonable temperature cuz we have been cooling it outside.
		The compressed Freon goes to a device which is similar in construction to the evaporator with tubing and fins.
		It is worth mentioning here that Freon 12, the kind of Freon we are talking about here, is no longer legal to be produced here in the USA (except in Arizona see the articlehere) so the cost of it has skyrocketed.
