Description

OptimAir is a water- and air-based induction unit with bidirectional air diffusion, recommended for a wide range of commercial applications—such as office buildings, shopping malls, retail stores, restaurants, and hotels—where a combination of ventilation, cooling, and/or heating is required. OptimAir is designed primarily for false-ceiling installations, but can be supplied with an optional Coanda frame for visible mounting. The unit is available with two plenum alternatives—normal (S) or higher (L) airflow—along with a high-performance heat exchanger to efficiently meet the cooling or heating demands of the conditioned space. For added flexibility, OptimAir can be supplied with adjustable nozzles that allow reconfiguration of the primary airflow even after installation. The nozzles are thoughtfully positioned above the heat exchanger to maximize the coil’s effectiveness and optimally mix the primary supply air with the induced room air. This ensures a well-conditioned indoor environment, enhancing both thermal and acoustic comfort for occupants. For additional efficiency, OptimAir can be equipped with a digital controller developed for DCV (Demand-Controlled Ventilation) requirements.

Function

The function of active chilled beams is based on the well-known 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.
