PRESSURE SMOKEPROOF SYSTEM
PROBLEM TO BE SOLVED: To provide a technique capable of maintaining pressure distribution of a fire disaster chamber in a uniform and desired state, regardless of layout of a partition and the like, holding pressure difference between an evacuation chamber and the fire disaster chamber in a proper state, for maintaining inflow of air from the evacuation chamber to the fire disaster chamber to a small amount and stable amount thereby suppressing diffusion of smoke in the fire disaster chamber, and securing an evacuation route with a preferable state.SOLUTION: A pressure smokeproof system comprises evacuation chamber air supply means X1 for performing pressurization and air supply to an evacuation chamber B communicated to a fire disaster chamber A being a habitable chamber 1 on which fire disaster F occurs, and further comprises fire disaster chamber air supply means Y for performing pressurization and air supply to the fire disaster chamber A while maintaining a negative pressure state in the fire disaster chamber A with respect to the evacuation chamber B.
【課題】間仕切りなどのレイアウトに拘らず火災室の圧力分布を均一な所望の状態に維持すると共に、避難室と火災室との圧力差を適正な状態に保つことで、避難室から火災室への空気の流入を少量且つ安定したものに維持して火災室の煙の拡散を抑制し、避難経路を良好な状態で確保することができる技術を提供する。【解決手段】火災Ｆが発生している居室１である火災室Ａに通じる避難室Ｂへの加圧給気を行う避難室給気手段Ｘ１を備えた加圧防煙システムにおいて、避難室Ｂに対する火災室Ａの陰圧状態を維持しながら、火災室Ａへの加圧給気を行う火災室給気手段Ｙを備える。【選択図】図１
