An air conditioning condenser is the outdoor device that powers central air through the ducts inside a building. It has vents on the sides and top, with a large fan that runs in the middle.
The air conditioning condenser works in tandem with the compressor to provide cool air. The compressor pressurizes the refrigerant and feeds it into coils that are wound inside of the condenser. As the pressurized refrigerant flows through the coils, the heat is lost, but the pressure is not. This cooled, pressurized air is then forced through a small valve that dispenses the liquid as a fine spray. The mist is circulated through an evaporator coil, which cools it even more and changes it into a gas. The resulting cold air is blown by the large fan into the air ducts to cool the interior of the building.
