Analysis and discussion on argument chain of optimizing smoke control scheme

Based on the characteristics of air flow, divides four pressurization air supply and smoke control schemes in the  item 8.3.2, Chapter 8 in the code into two kinds. Aiming at three kinds of smoke control schemes in the table 8.3.2-1,8.3.2-3 and 8.3.2-4 thereof, chooses representative examples, analyses ten different conditions by the method of flow distribution on equivalent flow area, establishes and calculates mathematic models of four subitems of each condition. Aiming at the smoke control schemes in the table 8.3.2-2 and 8.3.2-4, calculates and checks air volume parameters by hydro-network analysis method, obtains large amounts of data and a similar matrix data set, and forms a complete argument chain for optimizing smoke control scheme.
