Section 504.6 states "Makeup air. Installations exhausting more than 200 cfm (0.09 m3 /s) shall be provided with makeup air."
The laundry room I am designing will have 3 dryers which triggers 504.6. The engineer is telling me there is no off the shelf make-up air unit so he will need to design one. His design would be variable speed and tied to the quantity of dryers running. This is an expensive little sytem for a 3 dryer laundry room.
Has anyone run into and has an economical solultion?
There is an opperable window in the room. Can we say the window is our point of make-up air? Code does not specifically state mechanical means of makeup air.
I am interested to see how others dealt with this.
Thank you in advance.
