Closed Co2 room system climate control ?!

[PotHead3]

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.

oh of course if i used ac it would be a completely sealed room with co2

i think your temps should be fine if you make your ventilation better than it is. add extra intakes, and or add extra extraction fans

I've been researching this for the past couple days for my own build. A insulated room inside of a room in the garage. Looking at closed room systems and came across some info on window units which are an option for more. Just like described above, its pulling air from within the room, through the copper tubes and exhausting it cool back into the room. The fresh air modes, etc can all be controlled on most units with a switch on the back that closes vents to not allow fresh air to be pulled in via fan mode. For me the condenser side of it would be out of the room dispersing the hot coil air into the garage.

Main comment was to say there are multiple settings on a window unit that allow it not to suck out your co2.

that may work. just be sure to seal up the window ac unit so smell wont leak out

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.. )

Lol you do know that heat IS dehumidification, right?

So you need to condense moisture from the room, that means getting it colder than the dew point of the room. But that's also 100% RH so it needs to be warmed back up, aka heated to bring RH down.

Mine will put out 103* temps at timea

Well, my system is not closed room and I still been struggling with too high temps with every grow,,,because of too weak exhaust fans.
Now it all will renewed, anyway when the grow rooms was packed with too many huge plants what where super leafy , the RH where like close to 90 % in flowering . I couldn't get to my plants because there wasn't space enough (it will be changed also )..so I couldn't
pick enough leafs to lower the RH . I bought 2 dehumidifiers . The problem was that the temps where all ready like 89 degrees and
the humidifiers started pumping hot air in growing area to my surprise , didn't see that coming ,thought they would be just removing moisture, I hadn't had time to study more how these machines work so it was a lost cause.

That thing is a total joke unless you live/grow on a boat and even then you better have damn cheap electric rates.
"The OptiClimate has a water inlet and outlet, and the inlet is connected to the cold water supply. While the cold water is used to cool the air, it is heated to 35-50 °C. It is then discharged to the sewers through the water outlet"
