Air changes for large warehouse to calculate infiltration loads
Air changes for large warehouse to calculate infiltration loads
(OP)
Hello everyone. Can someone help me by directing me to a reference for air changes for large warehouses?
A typical warehouse would be 500,000 square feet and 30 feet high with many dock doors.
I have tried calculating the infiltration using the crack method but I read somewhere that for larger buildings the easier way to design it would be to use an air change/hour number to figure out the infiltration.
Can anyone help me out?

125,000cfm*1.08*20 = 2,700,000 btuh assuming you are using a 20 degree delta T. This transalates to 270 gpm additional water flow to pick up just infiltration, assuming you are circulating water to terminal units and that it will be water and not a form of glycol to the terminals. The gpm requirement will change with glycols.
Scary!
