The description given matches with Freon, which has been commonly used as a refrigerant and cooling agent in various appliances. However, it has been found to be harmful to the ozone layer in the atmosphere. Ammonia is another refrigerant but it is not inert, and it can be combustible or toxic. Antifreeze is not a refrigerant and is typically used for engine coolant. SO₂ and 0.444 m do not relate to any substance or concept in the given context.
