Krueger active chilled beams benefit from the use of using hydronic coils and induced air to reduce energy consumption associated with removal of sensible thermal loads. The primary air is supplied to the chilled beam subsequent to it being discharged through a series of nozzles located along the length of the beam. The nozzles inject the primary air into the mixing chamber at velocities capable of inducing plenum or soffit air through the water coil and where it mixes with the primary supply air. This mixture of air is then discharged into the space through ceiling slot diffusers. This provides high cooling outputs with low amounts of primary air. The reduced volume of air results in the reduction of the air handler capacity and size, smaller duct sizes, and the overall energy consumption. The BARs are offered for both cooling and heating, lengths from 2’ to 8’. They can be easily integrated with Krueger’s 1700 diffuser. Units can have the 1700 diffuser installed directly to the discharge of the chilled beam, or BAR beams can be located in specific locations above a long run of 1700 diffusers, creating active and inactive sections.
