Refrigerator cooling fans. These fans (black slats covering fridge) are at the rear of the fridge. They cover coils of pipes that contain a coolant gas that has removed heat from inside the fridge. This is done by circulating the gas through a set of internal and external pipes. In the internal pipes the gas evaporates and this causes a large drop in temperature. In the external pipes, excess heat is removed by the fans. The gas is compressed in a compressor (bottom centre) before being piped back into the internal pipes for evaporation and more cooling. Electricity is used to run the pump, compressor and fans.
