Supply and return air systems can be used in comfort rooms, such as offices for cooling up to Δt= – 10K. Mounting height 2.6 – 4m.
The pulsating air jet which enters the room horizontally reduces despite the low induction the end velocity of jet and the temperature difference very quickly. This allows the air to be blown into the room without causing draughts.
95 – 450 m³/h, use in VAV systems from 100% to 40%.
