Cooking Myths (Part 3)

It sometimes surprises people to know that a tightly-packed refrigerator or freezer is actually much more energy efficient than a loosely-packed one.

It shouldn't be so surprising. Air has almost no thermal capacity. We've discussed that in the context of an oven but the same principle applies to a freezer.

The things that keep the insides cold are actually the walls and the food and beverage items.

That's why a packed freezer will stay cold for a long time during a power outage.

So if you have a packed fridge like the CC, you can pat yourself for being more energy-efficient.
