What is the chemical formula for freon?
CCl2F2
Which refrigerant contains a CFC?
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.
What is the molecular formula of Freon 11?
CCl3F
What is Freon 11 used for?
Summary. R-11 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. It is a low-pressure refrigerant that was commonly used in centrifugal chillers and before the 1970’s it was used as a propellant for aerosols.
What is the correct formula for 1/2 dichloro tetrafluoroethane?
C2Cl2F4
What is the structural formula of Freon 114?
What is the designation number of chemical name tetrafluoroethane?
ASHRAE Refrigerant Designations

What are the properties of refrigerant?
Physical Properties of Refrigerants
- Low Freezing Point. Refrigerants should have low freezing point than the normal operating conditions.
- Low Condensing Pressure.
- High Evaporator Pressure.
- High Critical Pressure.
- High Vapor Density.
- High Dielectric strength.
- High Latent Heat of Vaporization.
- High Heat Transfer Coefficient.
Which refrigerant is the best?
The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.
What are the four stages of refrigeration?
The refrigeration cycle contains four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components and is contained in the refrigerant loop.
What is the most common refrigerant?
Chlorofluorocarbons (CFCs)
What refrigerant will replace R410A?
R-32
What is the replacement for R22 freon?
R-410A
What is the best replacement for 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 year did they stop using R22?
2020
How do I know if my AC is R22?
How Do I Know If My Unit Uses R22? If your home has an air conditioning system that was built before 2010, your AC could have R22. You can find the type of refrigerant your system runs on by looking at the appliance’s nameplate.
Is R410a going to be phased out?
All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment. But it’s not so much the air conditioning system itself, or even its cooling performance.
Is R410A more expensive than R22?
“The cost of R-22 is somewhere between $75 to $100 a pound, where the cost of R410A, which is the replacement that we use, is $30 a pound,” said Dan Brizee, the president of Brizee heating. “Not being able to get it is one thing, but having to pay for it is another thing.
Is R410A harmful to breathe?
EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate. INHALATION: R-410A is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur.
