Need help with CO2/Cooling of an enclosed area.

Hi.
I was wondering if someone could let me know the best way to cool an enclosed area with CO2 enrichment.
The lights are 2 1000 watt HPS in cool tubes attached to adjust a wings ,ala Al. B. fuct, over 3, 2x4 tables in a 4x6 arrangement.
So the entire area of the flood tables is covered pretty much end to end with reflector:-o.
Including the space around the tables, I figure I have about 32 square feet.
The ceiling is approximately 7.5 feet so that gives me around 240 cubic feet of space.
I am not using CO2 at the moment, but when my CO2 controller/monitor arrives, I will be wanting to make the space pretty much air tight, except for the cooltubes.
They will continue to be vented with a fan.
I'm assuming the cooltubes being vented will not cool the room enough
(85 degrees F?), even with CO2 being kept at 1500 ppm, So I was thinking I'll need to be making/buying some kind of device to help cool the room.
An air conditioner is out because it needs to be vented and will screw up my CO2.
I was thinking some kind of copper coil with cold water/antifreeze running through it placed in ducting attached to a centrifugal fan.
I know there are plans out there on the net for this type of thing but most use ice water pumped through, which melts and needs to be replaced too often.
Any suggestions to how I can accomplish this?
Thanks in advance...

I know you said air conditioner is outta the question but what about the wall mount air conditioner like a 7500 to 10000 btu. they are about 500 bucks but im pretty sure it would work at least i have seen them in grow rooms before that didnt use in or out vents. just a thought thats all.

The more you enrich with CO2 the higher the average temperature in the room can be. I face the same problem, but my temps are around 83 with a 1K watt and 400 watt air cooled combo. The CO2 seems to be letting the plants do just fine at that temp.

Josh, the reason I say air conditioners are out is simply because they have to vent their hot/smelly air somewhere. I have come across some split type air conditioners. From what I can tell the fan/coil and heat pump are separated by tubing, which a refrigerant runs through. The only thing is, these things seem very expensive. Anyone know of a model for a small area at a reasonable price?

Most air conditioners don't vent the hot air out of the room but just bring the hot air out and cool it before venting it back in.
They can be found very cheap as well. I paid $175 new for mine. 5000 btu.

What kind of air conditioner doesn't vent hot air somewhere? No offense, but it can't magically transform hot to cold. If you have a completely sealed room, (which I am opting for), I don't think an air conditioner will keep it cool for an extended period of time without venting...could someone elaborate on this as by no means am I an expert on cooling...lol
