Diffuse ceiling ventilation is an air distribution system where the air is supplied from the entire ceiling surface, giving a low supply velocity. The flow pattern in the room is controlled by the heat sources. The system generates high mixing and the air velocities in the room are not influenced by the flow rate to the room, but dependent on the heat load and heat load distribution. Experiments showed that the selected ceiling surface material had only a small influence on the performance of the system and that the room height and heat load distribution can have a strong influence on the performance.
