WIND TUNNEL STUDY ON CHARACTERISTICS OF VENTILATED ROOM WITH BALCONY IN CROSSWIND

Natural ventilation through a door of balcony side can be defined as a type of single-sided ventilation. However airflow in the balcony may influence characteristics of room ventilation. Knowledge from previous studies, for example... , the prediction method of ventilation rate of single-sided rooms, cannot be applied to a room with a door connected to the balcony. In this study, rooms with openable balcony doors in apartment buildings are targeted, and the effect of balcony itself on the characteristics of room ventilation in crosswind are analyzed through wind tunnel experiment. As a result we can state that to open one balcony door at leeward side is more effective in terms of room ventilation than to open a balcony door at other positions. The depth of balcony has an effect on room ventilation in the case of opening one balcony door. If there are two balcony doors open, the effect is very small.
