What is the use of CFC(Chloro Fluoro Carbon) in a Refrigerator?

● Early refrigerators used a variety of potentially unpleasant and dangerous chemicals for refrigerants, for example, ammonia and sulphur dioxide.

 

● Scientists discovered an entirely new range of chemicals known as chlorofluorocarbons, or CFCs, which were neither toxic nor flammable, seemed practically non-reactive, and had suitable thermal properties.

 

● They were introduced as refrigerants in the 1930s, relatively soon after their discovery. Later, in the 1960s, CFCs found another use as blowing agents for foam insulation, to replace the less effective glass fibre insulation then used in refrigerator cabinets.

 

● Alas, we now know that these chemicals have the potential to damage the ozone layer in the stratosphere. The ozone layer in the upper atmosphere, high above our weather systems, absorbs ultraviolet (UV) radiation from the sun and prevents it from reaching the surface of the planet, where it can be harmful to life.
