Q. Freon group of refrigerants are
Freon is the cooling agent used in most air conditioning systems. Every air conditioning system needs a refrigerant also called a coolant.
Freon group of refrigerants are stable, nonflammable, low toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants. These include the chlorofluorocarbons (CFCs) that cause ozone depletion and HCFCs (such as chlorodifluoromethane)
Freon is a word for certain chemical compounds, often used as refrigerants. Thomas Midgley, Jr. invented using Freon as a refrigerant. "Freon" is a registered trademark of DuPont. Freon was first used to describe chlorofluorocarbon (CFC) refrigerants, but it is now used to describe many other kinds of chemicals used as refrigerants. Refrigerants may contain carbon, chlorine, fluorine and sometimes bromine. For example, Freon 10 is carbon tetrachloride. Many kinds of freon are not toxic to animals. They also are cheap and work well. However, most refrigerants can reduce the amount of ozone from the upper atmosphere. Reducing ozone lets more ultraviolet light to come through. Too much ultraviolet light can cause skin cancer and cataracts and can kill off plankton in the oceans.
The chlorine part of CFC refrigerants can reduce ozone. Hydrochlorofluorocarbons (HCFCs) can also damage the ozone. Newer Hydrofluorocarbon (HFC) refrigerants do not have chlorine in them and do not reduce ozone in the atmosphere. Most refrigerants also increase global warming because they are powerful greenhouse gasses. These refrigerants increase global warming thousands of times more than carbon dioxide (CO2).
- Inflammable
- Toxic
- Non-inflammable and toxic
- Nontoxic and non-inflammable
Answer: Nontoxic and non-inflammable
