Cfc refrigerant list

R-22, commonly known by the brand name Freon, is a chlorofluorocarbon (CFC), while R-410A is not. As National Geographic explains in their article “The Facts of Ozone Depletion,” CFCs are the chemicals most responsible for damaging the earth's ozone layer over the past several decades.

Is R134a a CFC?

R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant. With the discovery of the damaging effect of CFCs and HCFCs refrigerants to the ozone layer, the HFC family of refrigerant has been widely used as their replacement.

Is R22 a CFC?

Freon is DuPont's commercial name for R22, a member of the chlorofluorocarbon (CFC) organic compounds that contains carbon, chlorine, hydrogen and fluorine. CFCs are produced as a volatile derivative of methane and ethane.

Is R134a a CFC or HCFC?

HCFCs replaced CFCs in many applications but are now phased out in the United States and cannot be produced anymore. Hydrofluorocarbon (HFC) refrigerants are compounds consisting of hydrogen, fluorine, and carbon. The most common HFCs are R134a, R404a, and R410a.

Is R-410A banned?

U.S. built refrigerators using R-410A refrigerant are banned starting January 1, 2021. HC-600a is currently the leading refrigerant for new U.S. built refrigerators. HC-600a is a blend of 50% isobutane (highly flammable) and 50% HFC-134a (non-flammable).

Are CFC still used in AC?

Production of CFCs completely ceased in 1995 and all new products do not use CFCs. Very old air conditioning units may still contain CFCs and can be replaced with newer, earth-friendly models by your local air conditioning specialist.

What are 3 examples of CFCs?

CFCs Examples

Trichlorofluoromethane- a methane hydrocarbon with one-carbon compound and replacement of the hydrogens with three chlorine and one fluorine atom.
Dichlorodifluoromethane- a colorless, slightly water-soluble, nonflammable gas. ...
Dichlorotetrafluoroethane- a colorless, nearly odorless nonflammable gas.

Which refrigerant is CFC free?

(*1)Refrigerants made from natural substances such as ammonia, and CO2 are CFC-free so they have less impact on the environment.

What are 4 products that used CFCs?

They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms.

Why is R22 banned?

Because R-22 depletes the ozone layer, production and import was further limited in 2010. In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. The production (not use) of R-22 is being phased out.

What replaced R22?

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

What refrigerant replaces CFCs?

Two of the chemical classes under consideration for replacing CFCs are hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs).

Why R-134a is not used in AC?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn't cool as well as R12. In addition, there was the lubricant issue. Because A/C compressors have moving parts, they require oil.

What is R-32 refrigerant?

R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.

What are the four types of refrigerant?

Here are the different types of refrigeration systems:

Evaporative Cooling. Evaporative cooling units are also referred to as swamp coolers.
Mechanical-Compression Refrigeration Systems. Mechanical compression is used in commercial and industrial refrigeration, as well as air conditioning. ...
Absorption. ...
Thermoelectric.

What is replacing R410?

RS-53 (R470A) is a new non-flammable Drop-in replacement for R410A with a low Global Warming Potential (GWP) less than half that of R410A. RS-53 (R470A) has a similar thermodynamic performance to R410A with matching energy efficiency and cooling capacity.

Which is better R-32 or R-410A?

R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate.

Can R-32 replace R410?

No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.

Why are CFC no longer used?

CFCs were phased out of production in developed countries by 1996, and in developing countries by 2010, under the Montreal Protocol because of the leading role they played in creating the so-called “ozone hole” in the atmosphere.

Is CFC banned in USA?

The CFC ban is effective January 17, 1994. After those dates, no person may distribute or sell such products in interstate commerce, including import and export of banned products. There is no ban on use of products already in the hands of users.
