INERGENT DESIGN CALCULATION WORKSHEET

Volume Calculations: Area

Area Name : Control Room

Length : m

Width : m

Height : m

Area : m2

Volume : m3

Volume Reductions :

Structural Reduction: m3

Reduced Volume : m3

Movable object reduction :

(If more than 25% of Reduced Volume)

Total Reduced Volume : m3

Room Minimum Ambient Temperature :

Design Concentration : %

Flooring Factor :

(From Table )

Initial Inergent Quantity Calculation:

Inergent Quantity :

(Total Reduced Volume x Flooding Factor) formula from the design manuam

Altitude Correction:

Height above or below sea level : m

Factor :

(from design manual)

Actual Inergen Quantity : m3

(Initial inergen quantity x Altitude correction factor)

(Ingergen Qty. /Cylinder Capacity to next whole number (Cyl. Qty. x Cyl. Cap.)

Cylinder Requirement : Total Cylinder Capacity :

355 ft3 cylinder

266 ft3 cylinder

205 ft3 cylinder

200, 250, 350, 425, and 435 cu. ft.

(5.7, 7.1, 9.9, 12.0, and 12.3 cu. m.).

Cylinder Size Selected :

Inergen Supplied :

(Cyl. Qty. x Cyl. Cap.)

Actual Inergen Loading Factor :

(Inergen Agent Supplied / Alt. Correction Factor) + Total Reduced Volume

Concentration Range Check :

(Design concentration must be between 37.5% - 42.8% for occupied spaces)

Room Max. Ambient Temp. :

Design Concentration at Max. Temp. :

(locate actual Inergen conc. At Max. Temp. on Table or use calc in Design Manual.
