Many scientists believe that refrigerants that contain hydrochlorofluorocarbons such as HCFC-R22 with chlorine are a contributing factor to this problem. R410A - a chlorine-free, non-inflammable, environmentally friendly and energy efficient refrigerant offers a new alternative, in addition to the properties just mentioned, R410A is an easy to handle as the environmentally unfriendly R22 because of its because of its pseudoazeotropic characteristics.
