Abstrakt

The main objective of ventilation is to provide good air quality for the occupants. For this purpose the necessary ventilating air change rate must be determined. Within displacement ventilation the estimation is closely related to the air flow rate in the thermal plumes when an air quality based design method is used. The vertical volume flux in a plume is influenced by many factors. Placement of the flow in relation to surrounding walls is one of them. This reduces the entrainment and is the subject of this article.
