air conditioner questions

Im adding a 5200 btu window a/c to my room. can some1 letme know the best way to run it. i mean with the exhaust vent. should i just set it at 75* and let 'er run or do i need some timers?kiss-ass4 HELP

dont window units vent out of the back..meaning the part thats outside of your window? if so you should set it at 78..with a temperature gauge..run it like that for a few hours and monitor it ..if it holds a steady 78 ..then there should be no reason not to go to 75..jmo

yeah they vent out the back which is into my garage. my concern is the xhaust pull all the cooled air right out of the room. should i put the exhaust on a timer too? or maybe a thermostat at like 82 and a/c at 75?

any help is appreicated

your back window goes into your garage ? there is no need to vent exhaust ..if your talking about an inline fan filter combo..im a little confused at your wording..see my above post..as far as my suggestion of cooling.

No i have my grow room in my garage where i will mount the a/c in the grow room so the back of the ac is in the garage. by exhaust i mean the air being removed from the grow area through a carbon scrubber, which will go into the attic. wont that vent or exhaust remove all the cold air the ac just made?

not all but some ..so yes try a timer..whatever you do monitor your temps..just for a little while..preferably during the hottest part of "your day"..get a feel of whats going on..thus giving you a hands on experience..if it's to hot for your plants adjust your thermostat..and your timer to work in harmony

Yes it will suck out your cold air to the outside. Is it possible to run the carbon scrubber (sucking the smell and the cold air) back into the room? Then have a seperate exhaust if you have a cool tube light set up to the outside and bringing in air from another room or wherever it is cooler.

The A/C will keep the room cool and the majority of the heat will be exhausted through the cool tube to the outside. I don't know how to draw a picture and post it on here but I wish I could show you how I did it before. Don't suck out your cold air to the outside. It would be a waste and extra expense.

out your light on a seperate circuit?

At first I would have sugested to use the cold air to just pull through the light then recycle that air back into the room. That will work, but then you have to recool everything down again. This might be ok, after all, once it gets cold it wont be working that hard to recool it again.

SO i gues try recycle then try a sep ciruit. When my grow room get colder than 50 degrees I turn off my 6 in. inline fan on my 400 watt and just let it sit. It only gets to 70 max. That is if I am lucky. Food for thought. If you keep it cold at 75 maybe this will all be cake.

1 recycle tha air. as in vent inside room. less smell worries too i bet
2 seperate circuit for light.

thanks for the help guys

I do plan on having the light vented seperatly a vent going from outside through the light and back outside.

Bluetick do you mean have the scrubber just connect to a fan both inside the room just to freshin the air? Is this what you call recycleing the air? do i still need to have a intake vent if i do this or is it more like a sealed room

If your already running a/c and an air-cooled light, then I would look at supplementing co2 and do without an exhaust.
Much easier.

You can do that too, and yes it would be easier. Just wish I knew how to draw something and upload it on here.

hey blue take a picture and load that i wanna see your idea. give it a try

I have the same problem as well.

I posted about it and got the same answers.

Look at this great setup

THANKS 10mm

Here is a picture of a set up I took a picture of some time ago. Not sure who I got it from but do this. Rather than the scrubber taking the air out of the room, let it intake and circulate in the room. Use the same spot for the exhaust but this will not be a cfm exhaust but rather a 4"-6" exhaust fan set on low to medium. Everything else is the same other than that. You will constantly be exhausting air and intaking fresh air in the room and the cool tube. The a/c runs in the room also. The cfm will be set on a timer so it will clean the air every 15 mins to 1 hour.

The room will stay the same temp, but if you were to exhaust the entire room with the cfm it would suck out the whole room of your cooled down air. Remember that the only reason the room isn't hot is because it has an a/c unit in it, otherwise the room would be very hot even with the cool tube. Leave the air in the room. The addtional heat will be exhausted at the top of the room constantly( also replacing the air in the room) with the intake, which will be running constantly and bringing in Co2.

you lost me blue, is the scrubber blowing outside or just filtering the air in the room, then a second fan exhausting on a timer? sorry if i'm retarded

The scrubber is NOT blowing outside. It will have to be a cfm fan for it to work with the scrubber so it will clear out your room in no time if it were exhausted outside. Put the cfm fan on a timer and just use it in the room, yes.

A seperate fan, though not a cfm can be used where it shows the scrubber exhausting the air instead. Just use a 4 or 6 inch fan on low or medium and on constantly.

This is all just another option for you. Anything will work but I prefer not to exhaust all of the air in the room with an ac window unit cooling it down. The purpose of the scrubber is to clean the air, which it will, and get rid of the smell as well. It doesn't have to take the cool air and smell to the outside. You still have circulation in the room with the intake and exhaust and of course the fan blowing on your trees.

have you used your srubber inside like that and is there relitivly no smell? and by the +rep to youy friend thanks for the info

Thanks and yes if you are not running your scrubber 24 hours a day there will always be smell. There is no escaping odor but just ways of dealing with it that are better than others. When you open the door to your room whether you are exhausting outside or in the room there is going to be an odor. Most people that I know exhaust their room every 15-30 minutes.

The question was regarding cleaning the air and also keeping the cool air inside of the room. Try it amigo and decide for yourself. If you are in the room when the cfm is turned on it will clean the air, same as if you are exhausting it. If you don't like it (which it will do the same thing), then exhaust it outside the room. If there was no window unit in the room, it would be ok imo to exhaust it to the outside.

Hey blue,
If I put my large portable AC in my small grow room (32 sq. ft.) and exhause its hot air into the attic, will it blow its own cold air out of the room too (just like a cfm exhause fan would)?

Maybe I need to keep it in my bedroom ducted into my grow room?
