I have a similar grow room to yours, mine will get up to about 92 to 94 some days in the summer.
Can you use a window fan? I bought a double window fan and used that for a while, but I got tired of worrying about it when it rained, and it was a nuisance to take in and out. It did cool the room.
Can you adjust some of the central A/C vents so that less cool air goes to other rooms and more to the orchid room? The humans might object to this plan, and of course it wouldn't help when the A/C is off completely.
Or your could set up a fan to exhaust air out of the orchid room into the rest of the condo, but that would also make it hot for the humans.
There are portable A/C units that sit on the floor and drain out into a pan on the bottom or a hose that you could ran to a drain somewhere. That would cool the air but also reduce the humidity.
Mostly, I just decided to give up and grow orchids that like it warm. I also have a humidifier so that the orchids aren't as stressed by the heat when it comes.
