I would be be careful about btu rating on portable a/c… I would say 80% are garbage and provide zero cooling… I have tried a lot of portable a/c.
Remember the portable unit generates heat and some btu needs to cool the unit itself…

I had good results with only one… edgestar 12000 btu… great unit evaporates all water in exhaust… prob good for 200 sq ft to 300 sq ft room… other units u have to empty water buckets… they make a 14k btu unit but I found no difference in the cooling.

One issue if the humidity is too high (ie raining) the cooling ability drops. You also need about 2 ft of space on each side of the unit, for efficient operation.

I got one cooling my server room right now with about 8 servers in it…

AP12000S EdgeStar Extreme Cool 12,000 BTU Portable Air Conditioner

and of course the best and most expensive portable is Portable Air Conditioners, AC, Spot Cooler, Outdoor & Computer Cooling... Serious cooling.

you can use the site below to figure out the heat load of the room… cooling depends on room size, number of windows, number of people, heat sources,etc.

Calculating The Size of a Server Room Air Conditioner

its more for IT rooms, but still useful for right sizing AC. Nothing worse the spending cash on a portable ac that doesn’t cool for crap..
