Restricting discomfort zones in the vicinity of window. Einschrankung der in Fensternahe entstehenden Diskomfortzonen.

One cause of these discomfort zones is cold air infiltration through window joints. This can be deflected using a warm air curtain. Describes tests showing that the degree of deflection depends to a large extent on the pulse ratio of the intermixing air flows. Describes chart compiled when experimental results were evaluated permitting determination of volume of air to bedischarged by nozzle convectors sufficient to diminish discomfort zone.
