Modern refrigerators only generate heat through the capture by refrigerant inside and the pump circulating air. Without those, it's a different story. A Peltier cooling device works similarly, but I can see it being more efficient overall since you would know where the heat ends up. Think car radiator or CPU heatsink. Same basic concept.
