Closed Co2 room system climate control ?!

Hi, I haven't found or understood the way how can they keep cool and avoid fungus in totally closed rooms
which run Co2....
A normal room can be kept cooler by removing hot air from the room ,but in the closed room system the same air stays there so the Co2 levels can be brought up to desired levels. Any AC system actually brings fresh and removes hot air thru tube from the room (unfiltered by the way, +removing Co2, so thats not the way to go )..
So can somebody explain how is the cooling done without bringing new air and not removing old and hot air from the room,,,I understand that the lights can be blown with a separate blower to keep them a bit cooler,,but the room is still heating up and fans are not enough to keep them cool...
So in my understanding there isn't a AC unit what could just sit there and suck the same air in and blow it out cool from the other end, all units do require a removal tube OUT from the room (this air is unfiltered and is lowering the co2..??!!)..
The only other AC system is the one what has a water container and sprays cooled water mist in the air (no good to increase humidity more in grow room, particulary in flowering)...
I'we seen videos of rooms like this but I still missed what is the trick to keep it completely closed and cool when there is several 1000 hps double end bulbs...? confused

Top left corner, dehumidifier maintains 40% humidity. We also have isolating fans all of the room to keep air moving because the dehumidifier won't prevent mold/rot on it's own. KIMG0504.jpg

Our mini does remove some, but not enough to bank on considering the condition's. The built in system is really more for moiture build up on the unit than for the room over all.

You know those coolers.....you wouldn't happen to have gone by boomer here before have you?

Sweet looking lab, I would use a white jacket if that would be my garden.
I bought 2 dehumidifiers what ended up in my storage very soon because they create more heat when operating ,so totally useless..
at least the ones I bought.
But the AC question interests me , make and models what are ultra quiet,effective, and don't require removal tube (any removal of hot air from room, only producing cool air....kind of a.. )

It's all in the numbers. We figure in everything from the dehumidifiers to the co2 burner to ensure we are buying the equipment we need the first time around.

a 15 cer 32,000 btu mini split from Ideal Air $2,500 and insulted ourselves. About $50 in wiring and breakers, took less than 2 hours and it was up and running.

While we do run a closed system we found that a fresh air exchange did make a difference in both temps and plant health. We also run an open scrubber in the room which removes the issue of smell.

Split type AC is the best if u can have a condenser outside. if not u can find sealed air cooled portable ACs that don't remove air from room and also water cooled ones. they are both awful compaired to a split.

I use a dual hose in my sealed room. I know 100% that is does in fact pull a little air from the room, I can see my ways pulling in from a bit of neg pressure. no biggie in my book, tank refills are cheap.

I can't install condenser outside, I would prefer a movable unit what I can put in the corner and it would suck air in from the grating at the back and from the grating at the front it would blow it out cool,,,no ducting no condensers nada, just simple and neat.
I wouldn't demand that it would be able to create an exact temp to the room just to be able to lover the temp like 4-6 degrees celcius..
Since that type machine doesn't really exist I think the only way to do it is, to have movable AC unit with ducting by the window and have the tubes a front of the machine what are pulling air in to the grow tent so they would get the cooled air pulled in instead of trying to cool the air inside the tent by an AC ..that way the unit can remove any air it likes out of the window without any fear of smelly unfiltered air.....it just would feel a bit more effective when the unit could be right inside the grow tent and cool that air,,,but I'll ques we have to wait for a dream machine with low power usage and no sound and no ducting and no condensation units...
And all my plugs are over crowded all ready and anything extra plugged in will cause fuses to pop...so end of the day there is that too to worry about.

ac doesn't work on the idea of using new fresh air to cool down the room. ac uses refrigerant in copper tubes to transfer the heat outside. The air it intakes from the room passes the copper coils like a heat sink and the copper coils have refrigerent running through thats cold that cools the room down. window units do the same but they have a control that can let fresh air in which is what you don't want. get a split unit ac and there would be no worries about losing co2 or letting smell out

Öhm.. not using the co2 system and not planing to use it ether...not possible in my surrounding have to be super stealth no noise no psuuh no sckweek or hummm.
I was just wondering how people are doing it because in my normal setup the temps are always a problem + power usage.

if you have filters running with a powerful enough fan. your temps will never be lower than the outside temp without using ac. if you are having temp problems now it may be you don't have enough air extraction to vent hot air and pull the outside temp air in. if your outside air is 100 degrees your grow room temp will not be able to get lower than that.
