Abstract
An air handling system for use in a building is used in combination with an elevated floor assembly for mounting on a principal floor of the building, this assembly including a working area floor which lies above the principal floor so as to provide an air plenum between the two floors. An outlet attenuator is mounted on the principal floor and extends upwardly through the working area floor, this attenuator including an exterior outlet housing having an air inlet at the top and a lowermost air outlet in at least one vertical side thereof. The air outlet is connected to the air plenum and is connected to the air inlet by a lower airflow passageway defined by interior walls. This attenuator includes sound absorbing material contained in the housing. An axial fan unit is mounted above the outlet attenuator and provides a downward flow of air to the outlet attenuator. There is also an inlet attenuator section mounted above the fan unit and extending upwardly to a ceiling of the building. The inlet attenuator has an exterior housing with an upper air inlet and a bottom air outlet.
