In the winter, when it's quite cold out, I often wonder why I'm paying to make cold air when there is free cold air available outside. What about a fridge that takes in air from outdoors?
We have a normal furnace/air conditioner combo (I live in a climate where summer air conditioning is essential), it has no concept of outside air temperature. I really would like a system where it doesn't have the concept of being set to cool/off/heat, but rather a concept of ideal temperature/heat-to/cool-to. Before running the high energy systems it looks at the outside air temp to see if it would be more efficient to turn on a fan to bring in outside air. It also will use that fan to adjust the temperature towards ideal but will not use the high energy systems to do so.
The HVAC should also be able to communicate with the refrigerator. If heat is desired in the house the refrigerator uses coils inside the house to dispose of it's waste heat. If heat is not desired it uses outside coils.
A huge part of an AC system (and, a fridge is basically a small AC unit) is dehumidifying as well. Functionally, you'd now need to add a de-humidification circuit to the system if you used outside air, since you don't have any humidity control.
That being said my mother keeps all the Christmas food on the balcony because it solves both the cooling and storage space problems.
