FreeAir is a water- and air-based induction unit with bidirectional air diffusion, recommended for a wide range of commercial applications—such as office buildings, restaurants, retail stores, museums, and hotels—where a combination of ventilation, cooling, and/or heating is required. Featuring an exceptionally slim, elegant design, FreeAir is specifically developed for exposed installations and is mounted directly under the ceiling. For enhanced flexibility and efficiency, FreeAir can be equipped with a digital controller, designed for DCV (Demand-Controlled Ventilation) applications.
The function of active chilled beams is based on the wellknown induction principle. The primary (dried) air from the air handling unit is injected into the plenum box within the active chilled beam and distributed through specially shaped nozzles. As the air is discharged through these nozzles, the high-velocity air jets above the coil create a low-pressure zone, which draws ambient room air through the coil. As it passes the coil fins, this drawn-in air is conditioned (cooled or heated) according to the water temperature in the coil. The conditioned air then mixes with the air jets before being discharged back into the occupied space. The careful placement and shape of the nozzles have a major impact on both the performance of the chilled beam and its sound emissions. It is important that the primary air from the air handling unit is sufficiently dry to maintain a low indoor dew point and prevent condensation. Because water is a more effective medium for heat transfer compared to air, chilled beams are an outstanding energy-efficient solution, reducing the overall energy needed for cooling, heating, and ventilation.
