hello growers and community of rollitup.

I have a question on mini spits, I have rooms built inside the warehouse. I placed the outdoor unit of the mini split inside the warehouse. If the mini split is rated 1666cfm for the outdoor unit and I put a carbon filter and exhaust fan in front of it or 4 feet away which is the exhaust fan is rated 1700cfm would in theory the temperature of the warehouse be the same as outside or still be hotter? Atm I am running ( 8 ) 24000btu mini splits and have ( 8 ) exhaust fans rated at 1060cfm. With outside temps at 31C , the warehouse is 40C.

Would exhausting even help in theory or no?

Thanks

I don't think anyone would really have an answer for this because it's such an odd setup for someone to have. In theory, yeah, the carbon filter should take care of some of the minisplit exhaust, but that is hot and humid air, no good for carbon filters. It would be hotter because the carbon is going to saturate itself with a lot of surrounding air before it even touches the minisplit exhaust. Sounds like you're trying to shortcut or or rig something up temporarily. Maybe if you tell us your end goals we can help you with a different route.

Yeah, exhausting will help, but you'd have to have great intake, and great exhaust, to account for the heat of your equipment.
