초록

The characteristics of moisture ventilation in a dry room are studied numerically The behaviors of moisture ventilation are analyzed by varying the aspect ratio of the horizontal plane and for various positions of the outlets in the room. Three different ventilation efficiencies have been used to examine the effect of the longitudinal arrangement of outlets and transverse arrangement of outlets for each aspect ratio on ventilation inside the room. It is shown that the ventilation efficiency in the dry room can be improved by arranging the outlets transversely in the cases that the aspect ratio is less than three and longitudinally in the cases that it is greater than four.
