Which refrigerant is most commonly used as a replacement for R-12 in new household refrigerators?

When R-12 was phased out, the goal was to replace ozone-depleting refrigerants with ones that are environmentally friendlier while still working well in household fridges. The most common replacement in new household refrigerators is R-134a, an HFC that has zero ozone depletion potential and similar operating characteristics to R-12. This makes it a practical drop-in for many appliances, with established service practices and widespread availability. R-22 is primarily used in air conditioning systems and is not the standard substitute for refrigerators. R-410A is also an air-conditioning refrigerant, not a typical replacement for refrigerators. R-600a exists in some modern European models and is flammable, so it isn’t the universal choice for new household refrigerators in most markets.
