These physical properties make them ideal for use as refrigerant gases in air conditioners, freezers and refrigerators. Their low boiling points also make them ideal for blowing agents for foam plastics, allowing the foam to expand as the liquid CFC boils.

Newer refrigerators have compressors that are designed to run 80% to 90% of the time. This makes them more energy efficient because the greatest amount of energy is used when the compressor cycles on as opposed to when the compressor is actually running.

CFC starts out as a liquid. The pump pushes the CFC through a series of coils in the freezer area. There the chemical turns to a vapour. When it does, it soaks up some of the heat that may be in the freez- er compartment.

In addition to fluorine and carbon, Freons often contain hydrogen, chlorine, or bromine. Thus, Freons are types of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and related compounds. The name Freon is a trademark registered by E.I. du Pont de Nemours & Company.

Forane® 22 refrigerant (R-22) is used in a broad range of applications, including residential and commercial air conditioning, refrigeration, chillers, room air conditioning, heat pumps, transport refrigeration, and other comfort cooling and refrigeration applications.

Once your fridge has been safely moved into the kitchen of your new home, it needs some time to settle before you can start using it. You should let it stand unplugged, in an upright position, for at least 4 hours to allow its compressor oil to settle. You can plug your appliance in once 4 hours have passed.

Perfluorocarbons are powerful greenhouse gases that were introduced as alternatives to ozone depleting substances. PFCs replace chlorofluorocarbons (CFCs) in manufacturing semiconductors. They are also used as solvents in the electronics industry, and as refrigerants of some specialized refrigeration systems.

is a trade name for a class of chemicals (known as Chlorofluorocarbons or CFC's) used as a refrigerant in air conditioning systems. Freon is a gas at room temperature and a liquid when cooled or compressed. Freon gas is colorless, non-flammable and relatively odorless. Some Freons have an ether-like odor.

Chlorofluorocarbon (CFC) refrigerants were commonly used in equipment manufactured before 1995. ... The atmospherically benign HFC refrigerants will remain in production, but CFC and HCFC refrigerants will be phased out. Production of CFCs ceased in 1995.

If your central air unit or AC is older than ten years old, it uses R-22 as the coolant. It is not something like a fuel though which can get used up over time. In theory, your air conditioner should never need more freon refrigerant. You will only need more refrigerant if there is a leak in your cooling system.

Chlorofluorocarbons (CFCs), once used as refrigerants and aerosol propellants until they were phased out by international agreement, are also greenhouse gases. There are three factors affect the degree to which any greenhouse gas will influence global warming, as follows: Its abundance in the atmosphere.

Chlorofluorocarbons (CFCs) are a group of odorless manufactured chemicals. Because they damage the earth's ozone layer, CFCs have been banned since 1996.

“Frost free” refrigeration refers to refrigerator units such as fridges and freezers that have built in technology to prevent the build-up of ice, by automatically defrosting itself after a set amount of time.

Yes, they are. Most refrigerants found in air conditioners, refrigerators, and freezers contain fluorocarbons, and many fluorocarbon compounds contain chlorine. ... The atmospherically benign HFC refrigerants will remain in production, but CFC and HCFC refrigerants will be phased out. Production of CFCs ceased in 1995.

When people used air conditioning units and refrigerators, CFCs were released into the atmosphere. In 1974, two California scientists suggested that CFCs released excess chlorine into the environment that was rising into the stratosphere and bonding with the trioxygen molecules.

Chlorofluorocarbons, also known as CFCs, consist of chemical compounds made up of chlorine, fluorine and carbon. CFCs are particularly harmful when released into the atmosphere because of their destructive reaction with O-zone particles, which provide the Earth with a protective layer against UV radiation.
