    Abstract

    The investigation is made in a room ventilated by an air distribution system based on a textile terminal. The air distribution in the room is mainly controlled by buoyancy forces from the heat sources, although the flow from the textile terminal can be characterized as a passive displacement flow with a downward direction in areas without thermal load.

    The system is extended by a personalized ventilation system to study the improved protection of people in a room. The investigation involves full-scale experiments with two breathing thermal manikins. One manikin is the source and the other the target.

    In general it is found that when the air is supplied from the textile terminal alone, the flow in the room is fully mixed with a limited protection of the occupants. It is shown that the personalized ventilation improves the protection of occupants by increasing the personal exposure index.
