Large Warehouse Ventilation
Large Warehouse Ventilation
(OP)
Hiya Folks,
I hope everybody is enjoying their last few weeks before the hot summer. It's a coincidence that I mention the hot summer, not really, because I've been assigned the task of determining the best method to ventilate one of our warehouses. During the summer, we experience heat indexes up to 110 F inside the warehouse when it's 91 F outside.
I calculated the total volume of the warehouse to be roughly 1,250,000 cubic feet. My first question is: What is the recommended ACH for a warehouse this bi? It stores chemical additives and one forklift operating inside. I've had a vendor come out and give a quote last year. In the quote, it was stated that they used a ACH value of 12. That would require around 250,000 CFM capacity. I found some fans that can achieve them, 11 to be exact, but I am curious on if this is absolutely necessary.
If the recommended ACH is lower than 12, then I could use less fans and reduce costs. But by using, for example a ACH value of 6, and using less fans, how much of a difference in delta T would I experience going from an ACH value of 12? What if I used a ACH value of 15? Would I see much difference in my Delta T?
Can someone please explain this to me or lead me to a source that would?
Thank you so much,
Tommy

Possibly some alarms in the event of a spill too.
You appear to need far more help than is reasonable to expect from a free web forum.
