how to incorporate a window AC in a SEALED room?? plus vent Q's

have been looking and havent found what i want I found the pic of the AC, but need suggestions and ideas how to put it to use with out loosing c02, and being the primary source of temp control, this can be in or out of the room, and i can build custom fittings for the AC.

and for the venting couldn't i just use a single intake fan to pump fresh air into the room when the lights are off?

put a/c in room. build box around a/c. cut hole in box and install inline fan. attach ducting to inline fan and vent heat out.

But beware of drainage, you'll end up with a puddle if you run it for a while.

Yes you could vent the a/c exhaust(heat) out by doing what drolove says and yes you will have drainage and condensation issues like 666 says. But you will also have two other negative issue. One being you would need to make sure a/c air is not too cold or plants will suffer, direct cooler air coming in which is far cooler(15+ degrees) then temps at canopy in the actual grow room is a negative. The second is more a CO2 observation/question, one wants a warmer room(85-90) if using CO2 so the plants can actually use it up, how hot is your room getting that you would even need an a/c in the room when using added CO2?

And what do yo do with the constant condensation (water) the a/c evaporator makes ? the condenser coil must have fresh air to circulate( can not use recycle air) so the freon can boil off back to a liquid state ,by not giving fresh air to the condenser coil the evaporator coil will not be able to properly remove the heat in your grow room , People think that A/C units (of any kind) Makes cold air ,A/C units remove hot air they dont make cold air .A/c is sized By BTU (british thermol Unit) this is based on 1 ton = 12,ooo BTU is the mesurment of heat removal per hr

If you are running a sealed room, you can easily build a box to enclose the AC in. Build the box in the top corner of the room hanging from the ceiling. By putting it at the ceiling you will have the best cooling effect. Make sure that the cooling vents are aimed up at the ceiling so it mixxes with the hot air before settling over the canopy. This will prevent any cold shock on the canopy.

Make the box 1.5to 2 times larger than the AC it will surround. Line the bottom of the box with panda tarp to protect the wood from condensation. Depending on the BTU rating of the AC, (not to mention the humidity in your part of the world) the box might need a drain line to remove the condensation. During final assembly seal all corners and joints of the box with silicon caulking.

you need to supply the box with fresh air flow at all times while the AC is running. You will need to install an inline fan connected to ducting in the same fashion that you would vent your lights. I.E. fresh air in, hot air out. Since this is going to be a sealed room, you will want to pull the fresh air from outside the room, through a duct and into the box. Then the hot air will obviously need to be vented outside.

I have run a sealed room for years, so here are a couple of tips.
1. It is AN ABSOLUTE REQUIREMENT that you use a dehumidifier. Your plants will be releasing a lot of moisture into the air, and in a sealed room it will be trapped in the room.
2. Buy a top of the line environmental controller to control every aspect. when running CO2, Any time the proper atmosphere (Temp/Humidity) gets out of wack it can screw up the growth for a day or more. I would expect to pay aprox $750-$900 for that unit alone.
3. DO NOT USE CO2 Generators!!!! Combustion= excess humidity. Use Co2 Tanks instead. Purchase more than one tank so you can have a full one ready as soon as the old one runs out.

FYI. A 20lb co2 tank will last 5-7 days in an 8x8x10ft room.

Hope that helped. Good luck to you and be safe.

Air conditioning are the process of altering the properties of air (primarily temperature and humidity) to more favorable conditions. More generally, air conditioning can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the condition of air.

a lot of a/c systems have a drip system that can be connected to a hose and routed out of the box, have either holes or a ducting that comes out one for intake and one for exhaust.

im trying to prepare for the worst, i have some germy's that are still at day zero and am about to start vegging, i want to grow a few out , sex them, then start cutlings. i have never done this, dont have any clue what to expect what to do or what to prepare for, im still learning about DWC and W/co2 the co2 is a fairly new idear and need to learn more beacuse ive learned that w/added co2 it changes the parameters , i got a 6x6x6 to work with sealed about 98%, but still kinda confused. this is a dry run not expecting to get anything but trying to work out the kinks b4 i get good genetics. it will a perpetual grow, im trying to develop a system to use, im using a 600w hps/mh. any useful links would help,,OOOOO im a picture person i learn alot better like that
