Hi All, I'm designing an exhaust system in brewery. Does anyone know the recommended air changes (ventilation rate)? My concern is the elevated level of carbon dioxide during the fermentation process. I'm planing on exhausting the air thru sidewall propeller fans and make-up the air thru roof mounted gas heated make up air fan. Please Advice.
Thanks
I would check with your local codes people first. If no code can be identified determine an equivalent indoor environment and use the recommended exchange rate.
The equation to calculate exchange rates is:
q = n V
where:
n = Change rate time (h^-1) hours
v = Volume to be exchanged (ft^3, m^3)
q = Air suppler rate (ft^3/h, m^3/h)
h = Hours
There is a course called Introduction Industrial Ventilation Systems on PDH Storm.
You get down load-able training materials and references.
