I am looking at using an in-room ac unit to help keep temps down in hot summer. I am looking at a dual hose model. It has an it has an intake hose and exhaust hose. It comes with a window kit to hook up hoses too. The exhaust needs to be hooked up to get the heat out of the room. But would it be better to let it use the intake inside the room as the outside temps will be 110°+? If it uses the cooler room air would it not run more efficiently?
Looking at this model but cant find an Amazon link: Whynter’s Elite ARC-122DS
I like this - it does not have an attachment that allows intake hose. Pulls air in through vent in the back condenses it and exhausts heat out of a hose that runs outside tent. Works really well. On amazon for I think 315 but they have a smaller model as well for 250
I had two cover all the intake vents with buckets then run ducting to those buckets.
Your idea will probably work as long as the room your using it in has some air infiltration but the unit will work most efficiently if both hoses are hooked up
I like the one you want to go w @Sirsmokesalot May I ask u if this is a solution as well or do u feel the one you are using is goon enough? The set up will be 4x8 idk the height yet but more than likely 8ft I don’t mind running exhaust out but I see that this one takes air in the room (hot) and converts it to cool air which serves a dual purpose there, as well as a dehum. Really just asking your opinion
@Countryboyjvd1971 can explain it better than I can since he is a HVAC guy by trade but you will need to exhaust outside of grow area. If not you will constantly be fighting a losing battle as it takes energy (with a product of heat) to cool the air. So if you did not you would be cooling the hot air you just exhausted and the cycle would continue constantly wasting energy and your temps would maintain a higher degree than I would like personally.
Like @TDubWilly said it helps to also have intake bring cool air in - for my setup I have a 315 cfm fan bringing in 69 degree air from my livable space in my house to the tent that has the a/c in it. Helps maintain ambient temps. His is a bit different since I’m sure he wanted to max out his space but is essentially the same concept.
So sorry I forgot to explain it all to get a warranted answer well I will be bringing in outside air lol naturally filtered of course through hepa but the outside air I have set up pulls air out of tent by doing this it is also pulling air in in through the hepa like an open loop hybrid where air is exhausted out but pulling in the new air with that being said it wouldn’t be recycling but the air I bring in so is this better explain it and make this sufficient @Sirsmokesalot@TDubWilly
So for my instance I would be better to just use the in house ac air at 80° instead of bringing in outside air which is 110° for the input side? So in theory I could put inside the tent or just inside the room to cool the room,11 x 13’total room. and the carbon exhaust filter in the tent would suck in the cooler air from the room?
Ok my room is 11 x 13’ and the tent is 4 x 8’. So I will get the dual hose I showed in the first post and vent the ac out to outside and just keep the intake hose and keep it in the room. I have the 6" fan with carbon filter for the tent and I will vent it to the outside also. Then I can close the door to the main room and with the house AC going and the room ac going I should be able to control temps a lot better. The carbon filter exhaust would pull air into tent from the cooled room.I am thinking the room ac unit would only need to run on the 12/12 cycle with the lights so it should not be too bad on $$.
If your running it in your house where there is already central air, and exhausting the hot air outside, a one hose system, two hose system, or a window unit should do great for you.
I almost think I know how the 1 hose and 2 hose versions work. If I had the 2 hose and took the intake hosed and put it in the tent through a ventilation hole and used the tent air it would be using warmer air from the tent to cool the room and then the cooler air would get sucked back in through the tent ventilation screens cooling the tent.
I think you’ll be sending unfiltered air straight outside and it will smell around your house in flower. Plus, if you have any other exhaust fans in the tent then the AC intake has to fight those to get air and the AC won’t work as well as it should.
This is a problem with the one hose unit as well.
When the intake is bringing in fresh air from outside then that same air is what gets exhausted.
When the intake is bringing in air that wreaks of cannabis, then that same air too is what gets exhausted.
Ok so this is my set up here I have an 10.10.10 gorilla unit. I have it set up to exhaust co2 at 20-30 min rate all this is set up through a charcoal filter w fan exhausting the air from top. opposite side cross corner I a hepa filter for the air that is being brought in through the exhaustion this is my loop system and if I left out info I will add but giving a basic description now in this scenario @TDubWilly which u it would I be better with the on I originally posted or what basically a 1oo sq ft tent 1000 cubic inside hps 1000w 4 as I will only be using a 4-4x4 W walkway crossing. Will the unit I originally posted work in this scenario due to the fact that I would be bringing in new air?
As for your question is there air infiltrating the system I’d say no besides the air I’m bringing in and co2
@RAP if u want to fun it like that the 2 hose system u have to start looking at option such as ozone to treat the room outside and then u could utilize that system I’d also link it w a filter kind of much though for the circumstances rather just get the right unit ya know but I do understand sometimes you got to do what you got to do
If you have zero air infiltration then you can’t use a one hose system but I bet you have more air infiltration than what you think.
Think of a bank vault that has no air coming in at all. If you put a one hose system in there then all that machine will do is exhaust and no air will be in the room for the machine to intake. On the two hose systems the second hose is an intake allowing it to get air from elsewhere.
