How Do Air Conditioning Coils Work?
- The coils inside an air conditioning unit are known as evaporator coils. These specialized coils are important to the functioning of an air conditioner. Window mounted air conditioners, central air conditioners and industrial air conditioners all use evaporator coils to provider cooler air for homes and businesses. Evaporator coils are also used in refrigeration with similar principles.
- An air conditioner's compresses takes Freon gas and compresses it into hot, high-pressure gas. The hot gas travels through the evaporator coils, where it releases its heat. As this occurs, the gas condenses into liquid form. This liquid then travels through the air conditioner's expansion valve, evaporating and becoming cool, low pressure Freon gas. This cooler gas then makes its way through an additional set of coils so that it can take in heat and cool the air inside a house or building.
- Air conditioning coils remove and evaporate humidity from the air that they cool. The phenomenon is similar to the condensation that develops on the outside of a glass of water. Evaporation and condensation are the processes used by air conditioner coils. An air conditioner coil changes the state of the air taken in by an air conditioner in order to change its relative temperature.
