List of cfc refrigerants

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 a CFC?

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 CFC used in AC nowadays?

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 replaced R-22?

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.

When did R-22 get banned?

In 2010, the U.S. stopped the sale of new air conditioning units that use R22. That means, new air conditioner in US manufactured after 2010 does not use R22 coolant. R22 phaseout in 2020 means that it became completely illegal to manufacture or import R22 itself into the country.

Which CFC is used in AC?

CFC-12 (also called Freon or R-12) has been the coolant most frequently used in automobile A/C systems and accounted for 20 percent of all U.S. CFC consumption in 1992. CFCs have been useful in many applications because they are non flammable, non toxic and extremely stable in the environment.

Is there any AC without CFC?

EIC Solutions' solid-state ThermoTEC Air Conditioners are manufactured with zero toxic refrigerants and CFCs.

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.

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).

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.

Which is better R-22 or r410?

Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it's more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.

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 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.

What replaced CFCs in refrigeration?

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

Can I put R410A in a R22 system?

You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force.

Is R22 still available in 2022?

R22 Freon is still available in April 2022. But, it's very expensive and now costs up to $1,300 for a 25-pound jug wholesale. That's up from $595 per jug in April 2021 and then $910 in August 2021. And, consider that most central air systems require an average of five pounds to recharge.

Can you buy R22 anymore?

As of January 1, 2020, production and import of R22 refrigerant will be illegal in the United States. Of course, continued use of your air conditioner (AC) or heat pump system using R22 refrigerant is allowed.

Why is R 12 banned?

The Ban on R-12 Refrigerant R12 refrigerant was the dominant refrigerant for decades, until 1975, when scientists discovered that CFCs, like R12 and R11, were harmful to the ozone layer. The fact that it was useful in so many ways was outweighed by its harm to the planet.

Can you replace R22 with another refrigerant?

If your unit runs on R22, you can replace it with a refrigerant alternative yourself or contact a professional to help you switch out the refrigerant. If the above options aren't viable, you do have the option of installing a new, modern system in which an R22 alternative is already in place.
