Can you share the calculation for the airflow of the room? I'm planning to do a familiar farm.
But mine will have some swamp coolers (since my area reaches outside ambient temperature of upto 48 deg Celsius in the summer).

For me it's pretty simple, because my farms are situated in a relatively cool climate (temperatures are rarely over 30 deg here in summer) - and most of the year in the 10-20 degrees range. I just made sure that my extractor fans were capable of moving more air than the miners would exhaust. Obviously it's important to ensure adequate intake also.

For 17 / 19-series Bitmain, expect up to 500cfm of expelled air per miner (credit @philipma1957).

So if you're running 20 of the above, your exhaust fans need to be capable of moving 10,000cfm (20 x 500). You should consider also that the exhaust fans may lose efficiency over time (e.g. as dust builds up on the blades) so it would be sensible practice to allow a margin on top of this (so 10,000cfm + 15% = 11,500cfm for 20 miners).

Depending on the country, the fan capacity may be quoted differently e.g. meters per minute or meters per hour - but there are plenty of calculators and formulas online to convert into cfm.
