How to cool a room open to outside temperatures?
(OP)
If I have a Oven Room (110 sqft) with one louver for exhausting air with a propellar fan and one louver for pulling in outside air.
What method do I use to size the fan (CFM-wise) in order to maintain my oven room to equal outdoor temperatures?
Lets just assume I'm generating 20000 btu/h from the ovens into the space and say outdoor temps are 85 degrees.

But, you can do the math: area*heat_transfer_coefficient*delta_temperature = heating rate
The HTC will be a slow function of the airflow across the oven.
Without some

q = 1.1 x cfm x (To - Ti)
q is heat load in btu/hr
cfm is airflow cfm
Ti is the entering air temperature that you are bringing in.
To is the exhaust air tempreature.

If there is a need for cooling, adiabatic cooling might be a solution (not knowing what your process is).
