> Things are more complicated if you scale the dimensions of the fridge unevenly.
They are. Unless you reach the scale of the walk-in fridge, you don’t want a fridge to be deeper than an arm’s length, and even small fridges have that depth because they’re designed to fit a kitchen top, which also is scaled for an arm’s length.
Vertical scaling is a bit more flexible, but will stop at about 2 meters (until you reach sizes that you can drive a forklift in)
On the plus side, if you scale things evenly, wall thickness also goes up, so heat losses per m² of area will go down.
