The idea is simple. We are told that opening the refrigerator door when its hot in the room is bad. It will only break the refrigerator and make the room even hotter.
But what if you could have an air conditioner plus a refrigerator in one product. Could this make things cheaper and more efficient. I mean with an air conditioner you release the heat outside. This is often overlooked for refrigerators as far as I know.
Here you release the heat outside for both the air conditioner and the refrigerator and at same time possibly share the inner workings of the cooling mechanism.
Another idea would be to make the refrigerator or fridge with tapered top. This to maximize efficiency. Like those Tipi tents.
