Refigerators commonly have a compressor to cool the freezer, and then a heat exchanger to equalize between the freezer and the fridge.
So the freezer can store energy by working extra hard bringing things down from -5C to -20C whenever it's expedient, and the equalizer keeps the fridge in its usual temperature range. Nothing spoils, and you don't even have to notice.
- thatwebdude 9y agoIt still isn't controlled by a timer or switch, though. That's the point I was opposing.

- thatwebdude 9y agoFood safety dictates a minimum chilling temperature, we can't override that without sacrificing health. We can make fridges/freezers more efficient and insulated though. My deep freezer (according to Energy Star) takes $24 a year to freeze my food. That already seems extremely efficient.
- askvictor 9y agoYes, but it's not going to be retrofitted onto existing fridges. You'd need to replace most of the fridges in the system.
