In this paper, 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 position of the outlets in the room. Three scales for ventilation efficiency have been compared for the cases of the longitudinal arrangement of outlets and those of the transverse arrangement of outlets for each aspect ratio. It has been shown from the numerical analysis 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 longitudinal in the cases that it is greater than four, respectively.
