  • HVAC: Air Handler Units

    Credits: 3 PDH

    PDH Course Description:

    AC systems provide conditioned air to an interior zone or space. This conditioned air is provided by air handling units typically located in a building's mechanical room. This course describes the basic components that are typically found in air handling units, such as the fan unit, flow dampers, vanes, fan blades, pitch drives, filtration systems, heating and cooling coils, mixing boxes, and humidification systems.

    Topics:

    • Basic Fan Types (Centrifugal and Axial)
    • Axial Fans (Propeller, Tubeaxial, and Vaneaxial)
    • Centrifugal Fans (Forward curved, Airfoil, Backwardly Curved/Inclined, Radial Tip/Blade)
    • Other Fan Types (Tubular-centrifugal, Inline centrifugal duct) Fan Classes
    • Fan Laws and Sizing
    • Fan Curves, System Curves
    • Fan Discharge Control
    • Discharge Air Dampers
    • Variable Inlet Vanes, Pitch Blades, Speed Drives
    • Heating and Cooling Coils
    • DX/VAV Systems
    • Filters and Filter Banks, Mixing Boxes
    • Humidification
