What are the Main Components of an AHU?

The main components of an air handling unit usually include the following major parts:

Fans (Fan): Used to drive air flow. Depending on the airflow requirements, the fan can be an axial or centrifugal fan. The performance of the fan determines the airflow and pressure of the system.

Filters: Used to clean the air and remove particulate contaminants from the air. Filter types include primary filters, intermediate filters and high efficiency filters.

Heating Coils: Used to heat the air, usually through hot water, steam or electric heaters.

Cooling Coils: Used to cool the air, usually through a chiller or refrigerant circuit.

Humidifier: Used to increase humidity in the air, usually by steam or spray humidification.

Control System: Used to regulate and monitor the various functional components of the air handling unit to ensure efficient operation of the system.

These components work together to meet the air handling needs of the building.
