Description
Active chilled beams supply conditioned primary (fresh) air to the room using heat exchangers to provide additional cooling and/or heating.
Primary air is supplied to the mixing chambers through nozzles (five options are possible). This allows secondary (room air) air to be drawn in through the recirculation grille and passed through a horizontal heat exchanger where it is heated or cooled.
Primary air is mixed with secondary air and supplied horizontally into the room through air outlet slots.
