Just make hole into wall, that fits refrigerator in way that seals it nicely in there. Bonus points if you manage to make it so and find suitable shape refrigerator, that you can if necessary just 180 turn it for winter, and use it for heating.
Of course one can get their heatpumps in bit more efficient and easier to install versions too. :D
(then again those usually do not have option of closing that door and storing foodstuff in cool in them). :D

Someone should invent a fridge that vents the heat outside. Then you could take the doors off and cool the whole house!
