Too much ventilation Air
Too much ventilation Air
(OP)
Hello,
This may be a simple one. I have a 12000 sq-ft white box finish out. It needs to have 2 RTU's @ 15 ton each. Fresh air should be at 25%. Can a baromtric relief damper on the unit compensate for the extra air brought in. Does it depend on the unit construction? Or do I need to relief the air by other means? The bathrooms exhaust 200 cfm.
Regards,

RE: Too much ventilation Air
My rule of thumb is 5-10% of the air will be lost thru the construction.
You want to leave 10% of the return air in the space for pressurization.
