Energy Efficiency and Air Handling Units
The air handling unit (AHU) is a complicated device involving many interrelated design selections that affect its energy efficiency. The overall efficiency of an AHU is determined by the energy it takes to move a given quantity of air against the system. Three major energy choices for the AHU design must be considered: [Hunt et al., 1990]
·Reducing AHU pressure drop,
·Incorporating the most efficient fan "system," and
·Displacing conventional cooling and heating energy. [Hunt et al., 1990]
