I'd recommend calling an appliance professional to evacuate the coolant. Attempting this yourself can cause health problems, but also can release the coolant into the environment. Neither is good.
A very, very old refrigerator could use Ammonia. Not many around anymore.
Older ones being phased out use R-12 (Dichlorodifluoromethane)
{CCL2F2} or Freon 12. all the same stuff.
Most of today's refrigerators are using R134a which was considered a better option for the environment.
However, according to the Montreal Protocol there is a phase out of R134a consumption going on. R134a is really bad for the ozone layer and by 2030 all HCFCs will be disallowed.
The best alternative for commercial refrigerators for now is hydrocarbon gases (iso-butane or R600a, and propane R290).
Tertrafluoroethane
freon
Methane
cfc
Neon gas is used in refrigerators.
cfc
Refrigerators can release freon.
Plasmafied lettuce
CFCs, or chlorofluorocarbons, which is the gas used in old refrigerators.
freon?
Most people own top freezer refrigerators. Only upper and middle-upper class people usually have side by side refrigerators.
Most refrigerators use a coolant called freon.
Freon gas is used in refrigerators, air conditioners, ovens and all other types of these things.
Most refrigerators are powered by electricity. There are certain, specialised refrigerators that can be run on propane, natural domestic gas, or on solar power using batteries.
Gas used in air conditioners are: R12 freon is dichlorodifluoromethane R134a is Tetrafluoroethane
No. Refrigerators use a substance called Freon that can readily change from liquid to gas to liquid, moving heat from inside the fridge to the outside. Liquid nitrogen is FAR too cold, and requires too much energy to make the change from gas to liquid.Yes, liquid nitrogen is used in refrigerators. Nitrogen is a diatomic gas. The two nitrogen atoms are bond with a triple bond.
