Portable Air Conditioners are designed around convenience and portability and are different and should not be compared to wall mount/ window units and central air conditioning. All of the cooling components are inside of the housing of the unit which sits in the room. They work with the air in the room and must vent using the exhaust hose, in which the heat from the room travels through to the outside.
