One good function is cooling while no-one's in the room, so that the fridge goes quiet when anyone is in hearing distance. Decibel limits for set times of day works about the same.
It's not just a pump, it's a linear compressor driven at any frequency or stroke length accoring to the situation, and there's a variable speed fan with lots of valves for directing cold air to where warmth is detected. It's hard to hear when the compressor starts because it slowly sneaks up to full speed and full stroke over a minute.
I still haven't dared to give my LG fridge-freezer network access, but it may have already found its way out via a neighbour's LG TV.
