Generator Room Ventilation
Generator Room Ventilation
(OP)
Hi,
A large generator room is located in a factory where 21 generators are located and natural ventilation is provided by only louvers.
These generators are tripping very frequently after installation, may be due to lack of enough ventilation requirement.
I have suggested forced ventilation of 30 ACH/HR by installaing additional exhaust and supply fans.
Can any body give me a best solution to overcome this problem.

Or maybe it's something else.
The first step in solving any problem is to understand the problem.
RE: Generator Room Ventilation
It has been confirmed from service personnel and generator supplier that there is no enough ventilation provided, further, they also recommended me to provide forced ventilation to overcome this problem.

Please check the data sheet of engine and the alternator and check the heat balance data. Try to find the amount of heat dissipated by the
-engine,
-alternator
-and the flue gas ducts.
With this information you should be able to calculate the amount of air flow required for the ventilation. In case you still need help, refer to ISO 8861.

I have improved several generator setups by ducting the waste heat from the radiators out of the room.

If air cooled the radiator fans should have more than sufficient air flow to ventilate the plant room (Assuming all discharge air is ducted to outside and not recirculated within the room!
If water cooled the manufacturer should be able to provide the heat rejected to the plant room.
Last generator room ventilation I designed required 12,000L/s ventilation per 2000kVA gen set (water cooled)

Once you have the heat rejected to the room from the gensets you should be able to come up with a more reasonable number.
