Abstract

In this paper, according to the approach built on previous paper (No.645,pp.1203-1209,2009.11), the relationship of air supply rate between the bulletin requirements in normal temperature and the conventional calculating method based on the condition in fire is constructed. The calculation procedure of air supply rate based on the ventilation calculation in normal temperature to satisfy the bulletin requirement is shown. Then the relationship in general of leakage by the position of air release opening is considered, the appropriate design for the height on floor of the air release opening and the calculation procedure of additional air supply rate to block smoke in fire are shown.
