Refrigerator or fridge-freezer combination

Please only buy a large one if you can fill it due to a large family. An "Übersicht" makes a fridge or freezer very inefficient because when opened, a large amount of air is exchanged, thus an unnecessary burden on the wallet and the environment.

Refrigerator in the kitchen with 0-degree zone, freezer in the utility room, mini beverage fridge in the pantry, 2 people, would also be enough for 4 people

An "overview" makes a fridge or freezer very inefficient, as a large amount of air is exchanged when it is opened,

This is offset again by opening it less often and for shorter periods, since everything is organized and you do not stand searching in front of the open door for a long time. In addition, an overfull fridge is also inefficient and has to cope with much more moisture. Therefore, I doubt in practice what initially seems logical.

Thanks to everyone for the answers :) I think I am now more in favor of a standalone refrigerator in the kitchen
