Question

Give Refrigerants (FREON) that are already phased out. Give the reason why it is no longer used

Answer 1

Answer:

The U.S. Environmental Protection Agency began phasing out R22 refrigerant in recent years because it was compounding the depletion of the Earth's ozone layer. Launching in 2010, the production and import of R22 was prohibited and by 2020, R22 will basically no longer be allowed.
