The definition of a distribution air is the process of moving air from one place to another. This process can be used to cool or heat a building, move air from one room to another, or to move air from outside to inside. It is a key component of any air conditioning system and is essential for maintaining a comfortable indoor environment. Distribution air is achieved through the use of ducts, fans, and other components that are designed to move air from one place to another. The air is typically moved through the ducts using a fan, which can be powered by electricity or natural gas. The fan then forces the air through the ducts and into the desired location.
