It produces less harmful gases like Chlorofluorocarbon, Hydrochlorocarbon. The feature of this gas is that it cools surroundings efficiently and does not harm the ozone layer.

Gas Used in Refrigerator

Tetrafluoroethane or Norflurane is the most commonly used refrigerator gas nowadays. Earlier, manufacturers were using ammonia and other harmful gases. These gases badly affect the atmosphere and increase the heat in the environment, harming the Ozone layer. Apart from Tetrafluoroethane, several other gases are being used that are less harmful.

As a known name, Refrigeration Gas or Refrigerants are being used in Refrigerators or Fridges to cool them from the inside. Earlier, Ammonia and Sulfur dioxide gas were used in early refrigerators, but they proved harmful to the environment and ozone layer due to leak issues. Later on, after several modifications, we are currently using Tetrafluoroethane, etc., in modern fridges and refrigerators.
