Brewery Ventilation

Brewery Ventilation

(OP)
Hi all I am designing brewery that has open fermenters and 1200 lbs/day CO2 produces. This room is 10,000 cuft. The number I came up with 2,500 cfm exhaust and supply with VFD controlled blowers and modulating ignition make up air unit.
I was wondering if there is any written documents by ASHRAE rate for brewery ventilation and would you recommend cooling also for make up air unit?
Thanks
Guy

RE: Brewery Ventilation

First things first, where is this brewery and what are the climate conditions.

If you want a good answer, there must be good data.

RE: Brewery Ventilation

How did you calculate the 2500 cfm exhaust rate

We are in Chicago our winter design temperature is -10. I count as 5cfm for 1 kg CO2 to keep it at 1000 ppm

RE: Brewery Ventilation

Where did you find 5 cfm for 1 kg CO2 to remain at 1000 ppm? I have seen the CO background run 600 ppm. Will this design be permitted in Chicago or use subburbs? FYI Chicago code had/has a bewery use of space. What is area of space?
