Maybe someone will do the math.

Some old farm houses still have that around here. But it is outside below a small hill or a slope. Some call it Kartoffel Keller. And some still use it for long time storage.
I am using a fridge outside: It is like a small balcony first floor with a roof and cool most of the year. So #1 and #2 are checked. For #3 I have a small Japanese compressor fridge in the kitchen, only for the very important daily things like milk. The mustard stays in the outside fridge. The kitchen fridge never uses more than 30W for cooling. But only IF it runs. So that checks #3.
Can anyone explain why almost everyone operates a fridge inside a heated house in winter while there is "a fridge outside". Would the fridge not need less power to cool down the insides when it's already cold outside?
Am I really the only one in this world with a fridge outside?
We have only very few days where we have extreme icecoldness around. It's a moderate climate. I never monitored how much less power it uses outside than inside... But It stricked me that the cooling cycles are much shorter in winter after I had put it outside.
