The chilled beam system is a popular energy saving system and it has been applied in Europe, the United States, and other countries for many years. There are two main types of chilled beams, such as the active chilled beam and passive chilled beam. The active chilled beam operates on the primary airflow, which induces airflow from the space through the cooling coil. This provides much more cooling capacity than a passive chilled beam working on a natural circulation flow. The efficient operation of the primary air unit is important to save the energy consumption from the fan and cooling capacity of the primary air unit. In this study, energy efficiency and efficient performance of the active beams with variable air volume (VAV) system was studied by simulation of the optimizing variable control parameters; the chilled beam efficiency difference was discussed considering the ratio between a primary air capacity and a chilled water capacity.
