What aspect does a central fan system specifically manage in buildings?

A central fan system is specifically designed to manage air distribution through ducts in buildings. This means that the system plays a crucial role in moving air throughout the space, ensuring that it is efficiently circulated and distributed to maintain comfort and air quality. The ducts connected to the central fan enable this distribution, allowing for controlled airflow to various parts of the building.

This system works differently from heating rooms individually, which typically involves localized heating units or systems that cater to specific areas or rooms. Compact cooling through localized units refers to systems that cool individual spaces rather than managing overall air distribution. Likewise, while evaporation of moisture content is an important process, it falls under different systems like dehumidifiers or air conditioning units that focus specifically on humidity control, rather than the primary function of a central fan system, which is directing airflow.
