It may be in the manual, or on a sticker on the system (along with electrical information (voltages, currents)). > An increasingly important environmental concern is the disposal of old refrigerators—initially because freon coolant damages the ozone layer—but as older generation refrigerators wear out, the destruction of CFC-bearing insulation also causes concern. Modern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, unlike Freon. R-134a is becoming much rarer in Europe. Newer refrigerants are being used instead. The main refrigerant now used is R-600a, or isobutane which has a smaller effect on the atmosphere if released. * https://en.wikipedia.org/wiki/Refrigerator#Disposal https://en.wikipedia.org/wiki/Refrigerator#Disposal * https://homeaffluence.com/what-coolants-are-primarily-used-in-refrigerators/ https://homeaffluence.com/what-coolants-are-primarily-used-i...
