i am working on a job with a problem
3 supply fans /800mm duct size at one end of room each at 5m/s flow direct from outside.3 extract fans sized as above 5m/s
the room is a rectangle 4.5 x 14mts long.
the room is used to remove heat buildup from a set of condensors.
there is also a control panel located within the room ,
the question is whats the air speed? is it safe to work in the room?
just to note i have been informed that useing the beaufort scale there would be a gentle breeze!
please give your comments
