Functional description
Passive chilled beams are used to dissipate high heat loads.
Warm room air rises due to thermal buoyancy, is cooled by the heat exchanger, then slowly flows downwards again to the occupied zone.

Convection
Passive chilled beams remove the heat from the room air and transfer it via a heat exchanger to the water (transport medium). More than 90 % of the heat are transferred through convection. As the air passes over the surfaces of the heat exchanger, its temperature decreases while its density increases as a consequence, hence accelerating the downward airflow. The air flows straight down from the top to the bottom of the unit. This further increases the downward airflow (stack effect) and hence the cooling output.
Heat exchanger
The maximum water-side operating pressure for all heat exchangers is 6 bar.
The maximum water flow temperature (heating circuit) for all heat exchangers is 75 °C; if flexible hoses are used, the water flow temperature should not exceed 55 °C. Units for other pressures and temperatures are available on request.
The water flow temperature (cooling circuit) should be at least 16 °C such that it does not permanently fall below the dew point. For units with a condensate drip tray the water flow temperature may be reduced to 15 °C.
Heat exchanger as 2-pipe system
Air-water systems with a 2-pipe heat exchanger may be used for either heating or cooling. In changeover mode it is possible to use all units within a water circuit exclusively for cooling in summer and exclusively for heating in winter.
