Description

Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant.


R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by 1,1,1,2-tetrafluoroethane (R-134a),When older units leak, retrofits to R-134a are recommended. Retrofit to R-134a requires complete flushing and filter/dryer replacement to remove the mineral oil. Mineral oil used for R12 is not compatible with R-134a. Some oils designed for conversion to R-134a are advertised as compatible with residual R-12. New rubber hoses which are R-134a compatible may be needed for the same reason.


1,1,1,2-Tetrafluoroethane, R-134a, Forane 134a, Genetron 134a, Florasol 134a, Suva 134a or HFC-134a, also known as norflurane (INN), is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential.

1,1,1,2-Tetrafluoroethane is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12 and retrofit kits are available to convert units that were originally R-12-equipped.


Competitive Advantage

Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications.


1) Safe properties: Refrigerant R12 is nontoxic, nonflammable, and non-explosive. This makes it highly popular for the domestic as well as the commercial applications.


2) Stability: R12 is highly stable chlorofluorocarbon and it does not disintegrate even under the extreme operating conditions


3) Suitable for wide range of operating conditions: R12 has the boiling point of -21.6 degree F (-29.8 degree C) due to which it condenses at the moderate pressures at the atmospheric temperature. This means the discharge pressure of the compressor should be only moderate so as to produce the condensation of the refrigerant in the condenser at the atmospheric temperature. This helps in using the compressor of low compression ratio that has higher efficiency.


4) Miscibility with oil: Refrigerant R12 is miscible with the compressor oil under all the operating conditions. There are two advantages of this property of R12. Firstly, there is no problem of the oil return back to compressor. Some particles of the oil from compressor tend to get carried away with the discharged refrigerant, because of the property of miscibility of R12, these particles return back to the compressor easily. The second advantage of miscibility is that the refrigerant flowing through the condenser and the

evaporator is free of the oil particles.
