A VAV air handler includes a cooling coil with a return air bypass damper for improved dehumidification. The bypass interjects into the supply air a portion of relatively warm, dry return air downstream of the cooling coil. This allows the cooling coil to absorb more latent heat from the incoming outside air and the remaining portion of the return air over a broad range of operating conditions, but especially at low load conditions.

A device for monitoring and modulating the admission of fresh air into a building. The device comprises a housing; a sensor associated with the housing and operable to measure airflow through the housing; and a damper including at least two damper blades. Each damper blade includes a shaft rotatably attached to the housing at least at a first shaft end. The shaft is located on the surface of the damper blade so as to divide the surface into first and second substantially equal areas.

An air handling unit has a fan wheel in offset placement and a plenum configuration preventing line of sight noise transmission into the air system supplied by the air handling unit. The fan wheel is so placed and the plenum configuration optimized so as to obtain the benefit of an eddy current stabilizer flow from the fan wheel, which provides a further improvement in the acoustic performance of the air handling unit.
