1KAPAK KONUSU -MAKALE 4. Notlar Araştırmacıların hava perdesi hava akış boyutlandırma prosedürü, acil durumda, ASHRAE yöntemine kıyasla daha tedbirseldir (hava akışı %20-30% daha fazladır). Buna ilave olarak, içeri hava akışı dışarı hava akışını dengeler ve çıkış yollarında güvenliği arttırır. Referanslar [1] NFPA, 1995. NFPA 92 8.
