View more6 FAQs about [Battery room exhaust fan]
Does a battery room need a ventilation system?
The ventilation system for the battery room shall be separate from ventilation systems for other spaces. Air recirculation in the battery room is prohibited. Exhaust air through a dedicated exhaust duct system if the battery room is not located on an outside wall.
How to ventilate a battery room?
The battery room shall be ventilated by means of two exhaust fans (one working + one standby). The standby fan should start automatically in case the other fails, Each fan shall have an independent failure alarm. The fan shall be mounted as high as possible in the wall, but not below the level of the light fittings.
How should a battery room be designed?
Battery rooms shall be designed with an adequate exhaust system which provides for continuous ventilation of the battery room to prohibit the build-up of potentially explosive hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
How many exhaust fans do I Need?
Exhaust Fan Requirements: Two exhaust fans (one working + one standby) are recommended, each rated for 58.66 cubic feet per minute. The air in the room will need to be completely exchanged every 1.17 hours or 70 minutes to maintain a safe level of hydrogen gas.
Do recombinant batteries need ventilation?
Also since the hydrogen released to the surroundings is highly flammable and explosive; these types of batteries must be installed in a sufficiently ventilated room. Most industry codes specify 6 air-changes per hour in the battery room. We will learn more on ventilation later in this course. Recombinant cells have a starved or gelled electrolyte.
What is a VS-24 vent fan?
This is to be used in conjunction with the HGD-2000 and HGD-3000 Hydrogen Gas Detectors. The hydrogen gas detector is mounted in the highest part of the room and the VS-24 vent fan is mounted through the outside wall. The system has four fans factory-rated at 850 CFM each. This conforms to N+1 for 2550 CFM.
