Why are fridges in cold climate countries not mounted into the wall of a house so the ambient air could cool the inside?

Too cold, and also you might be mildly confused by how a fridge actually works as well. A fridge does not ‘make things cold’, it merely exchanges heat with it’s environment. All that heat that was in the fridge is put somewhere else. If you’re in a cold environment where it would be cold enough to refrigerate food naturally you’d be heating your home anyhow. That heat that was in the fridge is just exchanged outward into the house anyhow, putting it outside would just mean a larger temperature difference. As long as there is a temperature difference between the fridge’s cooling bits(which are not inside the fridge, they’re at the bottom on the backside generally) and ambient air exists the fridge will work. Also once things are cooled down already they’re not inefficient at all.
