That's a very cool fridge. But how much difference does that make in practice? Air doesn't have much mass, right? How much energy does it actually cost to cool

Air doesn't have much mass, right? How much energy does it actually cost to cool the air in a fridge? (vs the solid parts of the fridge, and the food)
Looks like the OP's fridge uses 10-20x less power than a typical fridge, is that entirely due to the air not spilling out?
- lelandbatey 8mo agoMostly yes. Upright fridge and freezer designs trade off efficiency for convenience (rooting around in a chest fridge/freezer can be annoying). https://youtu.be/CGAhWgkKlHI https://youtu.be/CGAhWgkKlHI
- cogwheel 8mo agoDepends a lot on humidity. Condensing a fridge full of humid air releases a fair bit of heat. Also a fuller fridge will have much more thermal mass and care less. But yes, exchanging the entire air volume of a fridge every time you open it is very energy-wasteful.
