02-Fire Pump Room Calculations

The document calculates ventilation requirements for a fire pump room. It provides the area, height, and volume of the room. It then calculates the ventilation air required at normal operation of 6 air changes per hour (ACH) and fire operation of 10 ACH. The calculations account for 10% more fresh air being required during a fire. Based on the results, the required fresh air fan capacity for normal operation is 413 CFM and 688 CFM for a fire. The required exhaust air fan capacity is 375 CFM for normal operation and 625 CFM for a fire.

Calculation for Fire Pump Room Ventilation

Ventilation Fans will work at same ACH in case of fire @ 10 ACH & normal mode
with 6 ACH

Area = 34 m²
Hight = 3.15 m²
Volume = 107.1 m³

One Air Change 62.5 CFM

Ventilation Air Required @ Noraml Case 6 ACH 375 CFM


Ventilation Air Required @ Fire Case 10 ACH 625 CFM

assume 10% more for frsh air fan fire pump room should be +ve all the time

Ventilation Air Required @ Noraml Case 6 ACH 413 CFM


Ventilation Air Required @ Fire Case 10 ACH 688 CFM

Get Required Fresh Air Fan


Normal Mode 413 CFM
Fire Mode 688 CFM

Get Required Exhaust Air Fan


Normal Mode 375 CFM
Fire Mode 625 CFM
