R12 replacement. Propellant.
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.
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.
