The term Air Handling System refers to the equipment used to condition air to an acceptable level for distribution within a building. An Air Handling System utilizes various types of components such as fans (blowers), cooling & heating coils, heater compartments, sound attenuators, filter sections, mixing boxes, or combination mixing box filter section with dampers all arranged in a specific order. Within each basic component there are different types and styles, each with their own operating characteristics and efficiencies, methods and materials of construction, and costs - all of which greatly affect the initial design and resulting operating economics of the system.

The air handling unit, often abbreviated as “AHU”, is a very important component of a central air conditioning system. It is responsible for drawing return air from the indoor spaces, mixing it with outdoor air, and conditioning it to the acceptable level for distribution within the building.

The modular packaged equipment offered by various manufacturers is pretty standard. HVAC designers can simply spec the performance requirements and pick and choose from a wide array of standard building blocks to assemble a unit that meets their specific project needs. But a large majority of air handlers are custom built or tailor-made, requiring the HVAC designer to apply fundament psychrometric processes to precisely estimate the capacity and airflow requirements, select the fan, coil and other auxiliaries and integrate these properly with the building control system.

This 7-hr course outlines the primary functions of various sub-items of air handling units and discusses the key design considerations for estimating the capacity and airflow rate.

This course is aimed at Mechanical and HVAC engineers, Building designers, Operational & Maintenance Personnel, Project engineers and any other professionals who are interested in learning more about Air Handling Systems.
