These are the refrigerants which contain chlorine, fluorine, and carbon.
CFCs were banned in the late 80s because of adverse environmental effects.
Nowadays, it is estimated that half of the total CFCs have been improved.
R11, R12, R13, R113, R114, R500, R502, R503 are the top refrigerants covered under the group of CFCs.
Some of them are also known for the greenhouse gas effect.
Production of new stocks ceased in 1994.
HCFCs were referred to as the substitute of CFCs.
It contains hydrogen, chlorine, fluorine, and carbon.
They affect only around 10%, which is extremely less than the CFCs.
They are known as greenhouse gases.
R22, R123, R124, R401A, R401B, R402A, R403B, R408A, R409A, R414B, R416A are the refrigerants which are covered under the group of HCFCs.
It includes hydrogen, fluorine, and carbon.
So, if compared to other refrigerants, it has the lower potential of global warming.
Air conditioners that run on R410A are more efficient, offer better air quality, increase comfort and improve reliability.
R23, R134a, R404A, R407C, R410A, R417A, R422A, R422B, R422D, R507, R508B are included in the HFC group. This group of refrigerants is always in demand by refrigerant manufacturers because of its environment suitability.
Natural refrigerants are completely natural.
They are not created by any men like the other ones.
They do not harm the nature, environment, or the Ozone layer.
Moreover, they are quite inexpensive as compared to other refrigerants.
Air, HC, ammonia, CO2, H2O, etc. are the examples of natural refrigerants.
They have zero ozone depletion potential and negligible effects on global warming.
Most common refrigerants-
R134a (HFC)
R-12 (CFC)
R-410A (HFC)
R-22 (CFC)
R-404A (HFC)
