hello guys. i have a grow tent, cooltube,1 active intake and 1 exhaust fan.i will put a AC unit in the room where the tent in it.i will open all windows 2 or 3 times in a day for 5- 10 minutes to bring fresh air to room. and i wont add CO2.

air movement :
1) inside of the room > active intake > inside of the tent
2) inside of the tent > carbon filter > cooltube > exhaust fan > inside of the room.

is it good idea ? i read in other threads that extract to same room is not good idea . i want to do this in order to stabilize the temp and humidity . does this work without CO2 or do i miss anything else ?

Well your room will get hot, so you might have to run AC to cool the room, this way the air you put into your tent will be cold. You can always run some ducting from your room to the window, but if its stealth you are going for then that probally wont work.

If you are talking about using a window AC unit, you will not have to open the windows because the AC will be bringing in fresh air. Be careful though, the air that is exausted might smell like weed. You will most likely be ok there because you are using the carbon filter. AC tends to lower humidity so you will have to watch that, but temps should stay nice and stable. If you use CO2 be sure to turn off the AC and pump the CO2 into the tent. Good luck

Extracting to the same room is likely to create heat problems, and also co2 would have to be added to stop the plants suffocating. They will soon deplete the air of co2 in a sealed room if it's not being added.
Ventilation is key to running a successful op, that means getting stale air out, and fresh air in.

If you have the time to open the windows every few hours it's probably ok, you didn't mention you had such a big room.
