What are Hydrocarbon and Halocarbon Refrigerants?
- A Hydrocarbon ( HC ) is an organic compound consisting of only carbon and hydrogen atoms
- A Halocarbon is any compound which is derived from a hydrocarbon which has at least one of the hydrogen atom with a halogen
- Halogens are a group on the periodic table of elements which consist of five chemically related naturally occurring elements these include:
- Fluorine ( F)
- Chlorine ( Cl )
- Bromine ( Br )
- Iodine ( I )
- Astatine ( At)
- If the Halogen used to replace a hydrogen atom is Fluorine ( F ) then it is called a Hydrofluorocarbon ( HFC ) refrigerant.
- Essentially it means that some of the hydrogen atoms are replaced with fluorine atoms
- Popular Hydrofluorocarbon ( HFC ) currently in use are R-11 – R,14, R-113, R-114, R, 115, R-134a, R-410A, R-449B, R-1234zd
- The Fluorine ( F ) atom will reduce the flammability of the refrigerant, however this is not a green solution as Fluorine ( F ) is harmful to the environment
- Since Hydrocarbons do not have a Fluorine ( F ) atom they are more flammable
