Cold air sinks, so it collects at the bottom and, in a fridge freezer, the bottom shelves will be coldest. But in a fridge with an ice-making compartment at the top, it will be the top. Frost-free fridges circulate the air and have much more even temperature distribution.

Where is the warmest part of the refrigerator?

Is a fridge more efficient in a cold room?

A fridge works by taking heat from inside (by decompressing a fluid) and releasing it outside (by compressing the fluid in a radiator in the back). … If the room is colder, the radiator can dump more heat so the fridge is more efficient.

Does an empty freezer use more electricity?

If your extra freezer sits empty most of the winter, it’s using more energy than it does during the summer when it’s full of ice cream. A full freezer uses less energy than an empty one because the already-frozen food in it keeps the unit’s temperature low.

What refrigerator uses the least electricity?
