Need AC advice for a sealed room quickly

[resinryder]

I need to know the best way to heat and cool a sealed room. I'm gonna be moving within the month.I was going to go with a mini split unit and can get them at a decent price online. But that is where it stops. I can't get anyone here to install it unless they sell it and so far every price has been over 4000.00. And no, I don't know anyone who does this type of work.
Will a window ac unit with a heat strip pull the co2 out of my room? I've seen that the portable units will pull it out, but even with the portable I'll still need to be able to heat. I need 1 unit that will do both.
Any suggestions?

i cool with a portable, a double hose will not draw out the co2. and to heat i use an oil filled radiator heater. the heater is on a timer to make sure it dont compete with the a/c

Portables, IMO, suck sister ass. They never seem to actually cool as much as they are rated, and the general consensus is that they actually DO suck the CO2 out. They are also more expensive, BTU for BTU, than a window AC. This is mostly because window AC's are manufactured by the millions and sold everywhere.

Window AC's are not as easy to install as a portable, but they are hell of a lot easier than a split system or a standard ducted AC. They won't pull the CO2 out of your room as long you have them on "recirculate" mode.

The best way to use a window AC, if you don't have an actual window, is to build a wall that divides the room into the "grow area" and the "hot area." The AC is mounted in that wall with the business end in the grow room, and the back end in the hot area. The AC then dumps the heat from the grow room into the hot area, and you vent the hot side as normal. The heat winds up outside, but the odor and CO2 stays inside.

irie-I,man I used to think the dual hose units didnt rob you of co2 also,after all I learned it on OG and it made good sense to me lol.I'm telling you with absolute certainty,a dual hose unit with the intake hose put through a wall to another room will still totally rob your growroom of co2.I tested and retested checked and rechecked.Hey,wanna buy an almost new 500 dollar dual hose portable for 200 bucks lol?

Just pop a window unit in and you'll be fine, most a/c today don't have a venting option on the unit so they all just recirculate the air and you won't lose your Co2. I hope you don't have nosey nieghbors that will ask you why you run your a/c in the winter..lol
Peace...

Window units without a fresh air vent definately dont rob your room of co2,there is no smell emitting from it either despite what Rez said the other day.I run my AC 24 hours a day all year long.

FIW = If a window unit suits your needs / Right now (seasonal) at a lot of PAWN shops you will find NICE window units for CMEMORY = 50.00 should buy a nice one

my a/c unit does hot cold and dehumidity.... look for one of thoes....
it dosent rob you of co2 it actualy makes the plant able to use more co2 because of the temps...
whats a "heat strip" ...
"Will a window ac unit with a heat strip pull the co2 out of my room?"

 

[resinryder]

Thanks for the replies everyone. Think I may have to go with the window unit.
ZEROKOOL-The heat strip is avialabe in the larger window units so that it can be used as either air or heat.

Heh Resingyder,

Have you ever looked into a heat exchanger like seen here;
http://www.progressive-growth.com/heat_control-water_chillers-swamp_coolers.php
With this you just keep using the same air.It sucks the hot air in,cools it down with cold water through coilsand blows it back out cold again.Now for someone trying to cool down their sealed grow room and not waste their c02,this seems perfect.The only draw back would be you have to have either a remote rez for the fans or a constant supply of cold water,which shouldn't be too much of a problem depending on space,budget,time,ect. Hope this helps!

Reg,

REG, ^^^^^^^^^^^^^^^^^^^

IMHO those things are only good in low humidity areas where the "latent' heat in the air is low compared to a hot humid area.

the main thing growers need is the dehidification part of an A/Cs operation as that is how they "cool' the air (by removing the moisture).
"stealth sniper" on this forum has bought one that has three fans but he is tryin to cool an 8K watt bloom (i told him to be ready to invest in A/C cuzz i have my doubts)

the only way for them to work well is to have a "COLD" water source feeding into the coils (less than 50 deg. F) otherwise the differential will not be sufficient to do the job

mini splits can be bought online and they come with "layman" style install kits for those with a bit of common sense mechanical ability(ies).
try searchin for "SANYO", "Mitsubishi","LG", "soleus" to name a few makers of "mini-splits" just inquire and or check out the FAQ section on sites offing such wares.

"skull" my dual hose portable sucked my CO2 out too (bad investment for sealed rooms) since i went w/ the "other config" no problems for me either.
BUZZ!

I couldnt believe it and still dont really understand how the fuck it does it when the intake is in a totally different room lol,but I know 100% for sure it does it.My new 12K BTU window unit is handling the 3 1K verts. nicely though,and I have 12 degrees I could go down and 2 speeds stronger!I have my unit on low speed at 72 degrees and its 85 degrees under each vertizontal,I have 3 thermometers.I think I'll be good to go in the summertime too,the AC goes down to 60 degrees and has a kickass high fan

 

[irie-i]

im pretty sure my kenmore 12k btu is not exchanging air. i watched the co2 levels on my monitor with the a/c on and off, no obvious difference. my cd-6 fills the room in no time. and its supposed to be a little too small

 

[Guest]

Thats what I have a cd-6,I could've went with the cd-12 also,I'm sorta right in the middle.My room is 8 by 8 cube(just inches over) and 850 cubic ft.,cd-6 is made for 600 cu ft and cd-12 is made for 1200 cu ft,I could've gone either way.I burn for 8 1/2 minutes(850 cu ft.) every 45 minutes for 1500PPM,every hour would give me 1000PPM,every half hour would give me 2000PPM.

 

[Reg Dunlop]

BIZZ,

Yeah I totally agree about the humidity issue,but like I said,dependant on space,budget,time....
I think a heat exchanger used in conjuction with a dehumidifier and a remote rez for the heat exchanger would work,but I don't know for sure cuz I've never used one but logic dictates that it should work under those specific condtions?Right?I only ask cuz I'm about 1 step away from getting one of these units,for my sealed room,and other than what the store has to say about them,I really haven't found some one that uses them that I can see the results for my self,cuz $1700 is a big investment for what could be a glorified house fan.Do you have a link to that thread of stealth sniper?It would be graeatly appreicated.

Reg,

what about having an old fridge with a rez in it that keeps cool water and a hose coming out of that hooked to the heat exchange to make it work. it all seems to expensive to me that route and the portable ac seems right. any other portable ac runners that have something good or bad to say about them?
