Refrigerant in the air conditioner is a medium that has long used, serves to transfer heat from one place to another. The types of refrigerants including ammonia, sulfur dioxide, hydrocarbons such as methane, methyl chloride, methylene chloride, HFCs such as R11 (commonly used in refrigerators and air conditioners) and R22. Due to the realization that HFCs contribute to damage the ozone layer, the use of R11 and R22 then transferred to R-401A, R-134A, R-407C.
Ammonia is the refrigerant most commonly known. Ammonia can produce cooling with a fairly simple mechanism. Evaporation Ammonia is flammable, explosive and toxic. Ammonia is lighter than air.
Sulfur Dioxide (SO2) is not used and hard to find its use except in the cooling equipment is old. SO2 is not flammable or explosive, but is corrosive.
Hydrocarbons such as methane CH4, C4H10, isobutane, and propane C3H8 is often used as a fuel and is usually sold in cans. Methyl chloride is also commonly used as CH3Cl CH2Cl2.
Freon and Genetron®: chemists have also tried using carbon tetrachloride CCl4 as a refrigerant by adding two atoms of chlorine to produce CCl2F2 family that became known as "R", the R11 and R22. This is often referred to as Freon air conditioner.
HFC refrigerant or "CFC" non-flammable, non-toxic to humans and is widely used till then unknown bad effects in the atmosphere.
Water is used as a refrigerant still continues to this day as the heat transfer medium in air conditioner systems that use cooling towers which effective work environment where the humidity is low enough to produce a good level of evaporation. This system is widely used in the United States.
