The hot vapor to be condensed travels through a series of finned copper tubes. Smaller models, however, usually depend on gravity to circulate the air. In most large models, a fan is used to either push or pull the air through the condenser. (Copyright Dimplex Thermal Solutions, Kalamazoo, MI)Īir cooled condensers use circulating air to cool hot gases. They are the most used type of condensers. As the vapor loses its heat to the condensing medium, its temperature falls to the saturation point, and it condenses to a liquid.Īir cooled condensers use air as the cooling medium. Condensers make use of a condensing medium, such as air or water, that absorbs heat from a vapor.
