Answer 1

Air conditioners, fridges, freezers and all similar devices work on the same principle called pressure-temperature law (AKA gay-lussac’s law).

The pressure-temperature law states that when the pressure of a gas increases, it’s temperature increases too (and vice versa).

The basic idea is that you have a loop with gas inside of it. The other side of the loop is inside a barrier (like inside a fridge) and the other side of the loop is outside the barrier. In the part of the loop which is outside the barrier the gas is compressed making it release heat energy. Therefore you have moved energy from inside to fridge to outside the fridge.
