Packaged Air Handling Unit

A packaged air handling unit (PAHU) is a self-contained HVAC system designed to provide both heating and cooling to a building or specific zones. It typically includes components such as supply and return fans, heating and cooling coils, filters, dampers and integrated controls. The heating coil can use hot water, electric resistance or gas, while the cooling coil may use chilled water or a direct expansion (DX) refrigeration system. Filters clean the air before distribution, and dampers manage airflow and ventilation rates. The controls coordinate system operation based on the building's heating, cooling and ventilation requirements.

It is composed of:

• Air Handling Units

• Air Terminal

The 'Select HVAC Template' form provides options, to allow the user to configure the system with:

• A single AHU connected to multiple Air Terminals or multiple AHUs connected to multiple Air Terminals

• Choice of Spaces for Air Terminal
