what are cfc and hcfc refrigerants?

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated paraffin hydrocarbons that contain only carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon.

The interim replacements for CFCs are hydrochlorofluorocarbons (HCFCs), which deplete stratospheric ozone, but to a much lesser extent than CFCs. Ultimately, hydrofluorocarbons (HFCs) will replace HCFCs. Unlike CFCs and HCFCs, HFCs have an ozone depletion potential (ODP) of 0.

Chloro-Fluorocarbon, or CFCs, are sparingly used in refrigerators today. It is commercially known as freon, and can still be found on older refrigerators. The chemical begins its cycle as a pressurized liquid that expands into a gas as it moves through coils within the refrigerator's walls.

CFCs (stand for Chlorofluorocarbon ) are chemically very stable because they contain no Hydrogen. ... They don't contain a single Hydrogen and are the biggest contributors of ozone layer depletion. They are damaging the stratospheric ozone layer.

All CFCs are synthetic chemicals. CFCs were developed as replacements for toxic refrigerants. CFCs are made up of carbon, fliorine, and cesium.

Chlorofluorocarbons (CFCs) are a group of odorless manufactured chemicals. Because they damage the earth's ozone layer, CFCs have been banned since 1996.

What are HFCs and how are they different from CFCs? Hydrofluorocarbons (HFCs) are greenhouse gases containing carbon, hydrogen, and fluorine. ... Decades ago, appliances used chlorofluorocarbons (CFCs) as refrigerants, which wreaked havoc on the ozone layer and were phased out after the 1987 Montreal Protocol.

The most common source of CFCs are refrigerants, but fire suppression systems for aircraft and aerosols also emit CFCs into the atmosphere.

Chlorofluorocarbons (CFCs), including Freon, were used extensively as aerosol propellants. ... CFCs react with chlorine and break down, thereby destroying the ozone layer and allowing more radiation from the sun than is normal to reach the earth. Aerosol products have many uses, from hair care to cleaning and disinfecting.

This move comes after the ministry amended a set of regulations and renamed it as 'Ozone Depleting Substances (Regulation and Control) Amendment Rules, 2019. HCFC comprises inert compounds of carbon, hydrogen, and fluorine, and it is used instead of chlorofluorocarbon (CFC) as it is less destructive to the ozone layer.

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

LPG has come to play another innovative role as a refrigerant - It serves as the best contender to replace CFC's for domestic refrigerators as well as car air conditioners. R290 is the common name for high purity propane (C3H8) suitable for use in the refrigeration and air conditioning industry.

There is no production of CFC in an A/C. CFC is a refrigerant that is the heart of any air conditioner. It is a gas/liquid that is responsible to absorbing the heat from the chamber. This CFC gas needs to be refilled in periodically into the A/C due to minor leakages that may occur or the gas reaching its shelf life.

Certain appliances, such as refrigerators, air conditioners, and freezers, contain chemicals called fluorinated hydrocarbons. People often refer to these chemicals as Freon, which is a leading brand name. Freon is a dangerous substance.

Chlorofluorocarbons (CFCs) Their other important property is their volatility, having boiling points close to zero degrees Centigrade. These physical properties make them ideal for use as refrigerant gases in air conditioners, freezers and refrigerators.
