Which refrigerant is known to destroy ozone

Chlorofluorocarbons

Explanation:

Refrigerant used in refrigerators are chlorofluoro carbons. The release of these halogen family chemicals are harmful to the ozone layer.

Ozone layer is the layer that protects the Earth's atmosphere from the harmful Ultraviolet rays that are coming from the Sun's radiation.

These Hydrofluorocarbons heat the stratosphere, and this heating brings about chemical reactions and the molecules released in that process are capable of depleting the Ozone layer.
