As a practical matter in these discussions, "residential" is 120v compressor driven. Hardly anybody has a 12vdc house, though I'm sure someone will come up with some examples (e.g. an offigrid home). A 12v compressor fridge would likely be termed "marine", though that's not strictly true either. And an absorption fridge is typically called an "RV fridge", and that's obviously not 100% accurate either.I was under the impression that a "residential" refrigerator was simply one that is compressor-driven, as opposed to the absorption-type. Whether 12v or 120v, if it has a compressor it's "residential". Am I wrong? Does it have to be 120v to qualify as residential?
Casual use terms are rarely perfect.
