In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational conditions, are principally produced as temperature and velocity distributions.

Special attention is paid to the evaluation of indicative parameters of comfort for human occupants, like maximum value of velocity airflow in the occupied portion of the room and horizontal and vertical temperature gradient. Dynamical and thermal efficiency are also analysed by monitoring key functional parameters for active chilled beams both in winter and summer season applications.
