What refrigerants are CFC?
What refrigerants are CFC?
CFC = ChloroFluoroCarbons Chlorofluorocarbons are refrigerants that contain chlorine. They have been banned since the beginning of the 90’s because of their negative environmental impacts. Examples of CFCs are R11, R12 and R115.
What are CFC 11 and CFC 12?
CFCs or chlorofluorocarbons are compounds that are essentially inert in the troposphere. The main compounds used as tracers in natural systems are CFC 11 (CCl3F), CFC 12 (CCl2F2) and CFC 113 CCl2F-CClF2). The trade name of CFCs (DuPond) is Freon (F 11, F 12, F 113).
What are 3 CFC refrigerants?
Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. A blend that contains a CFC and any other product is still considered a CFC refrigerant. HCFC Refrigerant: HCFC refers to the chemical composition of the refrigerant.
Why chlorofluorocarbon refrigerants are banned?
Because CFCs contribute to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) including R-410A and R-134a.
What is the CFC exam?
CFC certification exam questions include safety and environmental topics such as how to recycle equipment and refrigerant properly. You might also find questions about the risk of CFC exposure, requirements for leak repairs and major versus minor repairs. Other exam topics might include: Environmental and ozone impacts.
What was CFC-11 used for?
CFC-11 was commonly used as a propellant gas in aerosol cans, a refrigerant in air conditioners, and as an insulating agent in the construction industry.
Is CFC-12 still used?
While use of CFC-12 in new vehicles has been banned since 1994, some vehicles built before then may still use it if they have not already been retrofitted to a non-ozone depleting refrigerant and they are still on the road.
What are the different types of CFC refrigerant?
Different Types of CFC Refrigerant. CFC-11. Trichlorofluoromethane, known as CFC-11 or the DuPont trade name Freon-11, is a CFC that was once widely used in the refrigeration industry CFC-12. CFC-113. CFC-114. CFC-115.
What kind of refrigerant does CFC 114 have?
Dichlorotetrafluoroethane, or CFC-114 (molecular formula C2Cl2F4), is a pollutant with refrigerant properties. The EPA lists CFC-114 as a Class I Ozone-depleting Substance. It was once used as a coolant in refrigeration units and known as Refrigerant 114 or R-114 in industry terms. CFC-114 has a lifetime of approximately 300 years.
What can I do with a CFC file?
CFC files are commonly used for storing components that execute database queries and manipulate data. However, they may also contain many other types of functions. Open over 300 file formats with File Viewer Plus.
Which is the most common CFC and HCFC?
The two most common CFCs and HCFCs are R-12 and R-22 Refrigerant. R-12 was the first type of mainstream refrigerant on the market. It took place of other more difficult to use refrigerants such as Carbon Dioxide. In the 1950s R-22 became popular and eventually became the main refrigerant to use in home and commercial air conditioning units.
