Active beam systems have become popular in North America as an energy efficient HVAC solution, utilizing tempered (56 to 59°F) chilled water delivered at or above the room dew point to accomplish most of the zone sensible cooling using dry cooling coils. This allows ducted airflow rates to be significantly reduced resulting in smaller air handling and distribution components. Application of these systems require control of both the air and water distribution systems at the zone level. The control and maintenance of acceptable space dew point levels is also required to avoid condensation on the cooling coils.
