Anyone with tips on how to size vent system for multiple dryers in a laudramat? I have 20 dryers. 1 to 20 can be running. Dryer rep says he knows of no case where more than 2000 CFM were used-but dryers specs are 220 CFM each.

assuming gas fired dryers provide osa for combustion and then provide additional for occupancy. if you want to apply a diversity factor for dryer usage then i assume you would have to guess. i think typical make-up would be through an evap coolerwith exhaust balanced to be equal the osa minus the dryer usage factored with your assumed diversity.
