Dadanco Horizontal Discharge Bulkhead-Mounted Chilled Beam ACB™ 10

With active chilled beam systems the building’s primary/ventilation air is continuously supplied to the active chilled beam terminal units by the central air handling system. This primary/ventilation air is cooled or heated to partially handle the temperature-driven sensible loads, while in the summer being cooled/dehumidified enough to handle all of the internal moisture-driven latent loads. Primary/ventilation air is ducted to the beams primary air chamber and introduced into the beams lower chamber (housing the beams heat exchanger) through a series of nozzles. This induces room air up into the beam via a perforated face and in turn through the heat exchanger coil. As elevated temperature chilled water or low temperature hot water is pumped through the heat exchanger coil (from the central plant) the induced room air is cooled and/or heated to the extent needed to control the room temperature. The now cooled or heated induced room air is then mixed with the primary/ventilation air and the mixed air is discharged back into the room via lateral linear slots
