Feature Presentation:

Establishing Primary Air Flow in Active Chilled Beam Systems

An Active Chilled Beam is a combination air-water system that uses the energy conveyed by two fluid streams (air and water) to achieve the required cooling or heating in a space.  The air supplied by the central air handler to the Active Chilled Beams is called primary air. The primary air is supplied to the Active Chilled Beams at a constant volume and at a relatively low static pressure (typically under 0.5” w.c.).

Within the Active Chilled Beam unit the primary air is discharged from the primary air plenum into a mixing chamber through a series of nozzles. A zone of relative low pressure is created within the mixing chamber, thereby inducing room air through the secondary water coil into the mixing chamber. The induced room air is called secondary air. The secondary air mixes with the primary air, and the mixed supply air is delivered to the room.

In the cooling mode the primary air is normally delivered cool and dry, satisfying a portion of the room’s sensible load and all of its latent load. The secondary water coil within the Active Chilled Beam is supplied with chilled water to satisfy the remaining sensible load of the room. The chilled water temperature is always provided above the room design dew point temperature to preclude sweating/condensation on the water coil.
