The fans in the air conditioner blow the air through pipes that lead to outlets that are in the car. Airplanes on the other hand need a special air-conditioning unit. A lot of these units are made of aluminum because it helps save weight. The refrigeration and air conditioning units in large planes can be found in the wings. In small planes, they can be found in the body of the plane.
Air turbines are what drive the unit of refrigeration.
Air pipes put the conditioned air to different parts of the airplane. Ships have refrigeration units that are installed in either the engine room or in a mechanical equipment room. The air conditioning units can be found throughout the ship. The air conditioning equipment used for ships has to be really strong to be able to hold up to the rolling and sloping motion that comes from the water. Central air conditioners use either gas or electricity.
