What is Refrigeration Gas?

As a known name, Refrigeration Gas or Refrigerants are being used in Refrigerators or Fridges to cool the eternal surroundings. Earlier, Ammonia and Sulfur dioxide gas were used in the early refrigerators, but they proved harmful to the environment and ozone layer due to leak issues.
