Evaporative (swamp) cooler for drying room?

Thanks for the link to the humidistat..

I just googled "Why isn't my swamp cooler cooling?" & I think I understand now why it failed to cool the room off even though it did effectively raise the humidity as I'd hoped.
Apparently, keeping the room sealed while it was running was the reason. I read that you need to provide a fresh outside air source from the opposite side of the room & create the proper air pressure before it can effectively cool.. (I forgot because it's been years since I've used it)
so I'm going to try that & see what happens..

If it works, I'll probably order the Inkbird humidistat to auto-control it since my unit doesn't have one built in.
If it doesn't work, I'll probably order a digital humidifier that has a humidistat already built in. They sell these as well on Amazon for around $50.
Frankly, I think the swamp cooler would be the best solution for me because it cools, lowers humidity & produces air flow -all of which I need.
A/C cools but also removes humidity so can't be used in conjunction with a humidifier.

Thankfully, the weather is cooling down here: upper 80's by day & upper 50's at night which'll make things a bit easier.

Thanks very much for your help!

PS: I haven't tried the bathroom test with the tub of water & a fan yet, but I did take a shower & the humidity shot up to 88%, lol. I left the door closed afterwards & it dropped down to 40% within an hour. I'm guessing this idea is whack, but will try it anyway to satisfy the mad scientist within the next time I take a bath... :)

Yep, swampy is not like an a/c unit. You have to provide a place for the air to go. If I do not open my upstairs windows when it is on, the air just gets muggy in here.
 
I decided the bathroom is the best possible place for drying as it's the coolest, smallest, darkest room in the house.

Bathroom test:
By partially filling the bathtub with water & placing a small fan pointed at it at low speed with the door closed I was able to raise the humidity pretty easily. It was 34% when I started & rose to 60% RH 1/2 hour later. Temperature only dropped to around 75F though.
Next, I tried putting my swamp cooler w/ice-filled reservoir in there & opened a window & the door slightly.
Again, I was able to easily raise RH well over 50% but the room got no cooler than 75F after two hours.
I guess drying at 75F will have to do as I can't think of a cooler place/option.
