Why refrigerators need power when cooling is actually loss of heat(energy)? Why energy is needed to lose energy?

Question

And shouldn’t it be a power generator

In: Physics

Answer 1

The cooling action of your refrigerator works just like an AC. In order for it to cool what inside, it has to pump heat out into the room, which takes energy. If you look at your refrigerator it should have a radiator somewhere, you’ll notice that this radiator is hot.
