aircondition

[tromeros]

Hello everyone good day.

i have a question

i want to run a grow and the temperature is about 35 celcius in the growbox and i want to lower it down i probably need an airconditioner..

now the question is this if the airconditioner works like that

The cool air will blow to the inline fan and the growbox will be COOL and i must have closed windows and doors of the room so we dont waste electricity and sweat

how the room will be ventilated with fresh air going to my plants if i keep close windows and doors..?

i must open the windows often so new air goes in?

thank you..

cheers

if i place a box at the left of the a/c there the roomair goes in and somehow put a duct between the box and the window so fresh air comes in its ok?

please someone help me i have to find a way at this issue..

just buy a window unit.

single duct portable units are utter dog shit. two duct units are also dog shit.

unless you already have the portable unit, and cannot return it, you are wasting your time trying to retrofit it to suit your needs.

these units have piss weak blowers and will not be able to push anything though any appreciably small duct of any appreciable length.

you really want a window unit... preferably a good one. just have your box or what ever intake air from the room this unit is installed in. exhaust the hot air somewhere else... preferably close to a return air register.

in my country they dont sell window units and i need only 5 degrees celsius down..thats why i mention about a portable ac unit..

can you get a two duct unit? they will cost more, but will be worth it in the longer run.

beyond being inherantly less efficient, single duct units like you noted, suck conditioned air from the room they are placed in. they therefor create negative pressure inside the conditioned space, and pull in air from under doors, through cracks, through leaks etc.

they will expel any odors outside as well.

i can find two duct unit only from amazon etc but it is hard because i am far away and the shipping is like the price of an ac thats why i thought to place the box there the room air goes in the ac and dut it to the window..

 

[queequeg152]

you can try this retrofit... but its going to be difficult to do properly without a decent amount of skill.

the problem is that the blowers these things use to exhaust the air are exceptionally weak, so weak that they cannot effectivly cope with the additional duct and other crap that you will add in retrofitting this thing.

this is what i would do...
use the biggest duct you can.
build a plenum box from foam board, or even better... fiberglass ductboard.

fasten this box as best you can, to the side of the unit. consider cutting away the plastic housing that is interfering with smooth air flow.

attach something like a 6 or 8" duct to the box with a duct collar.

seal it all up with fiberglass scrim and unfibered duct mastic. smear the mastic on fairly thick... like a 1/16th of an inch.

very small gaps can be sealed with cheap acrylic caulking.

if you cant get duct mastic... try great stuff canned foam. but keep in mind that canned foam is shitty, and brittle.

i highly recommend using mastic. when it dries its like hardened chewing gum.

build a window insert out of foam board and plywood... drill and install both ducts into this insert with something like dryer vent caps.

verry good advice but where is the diference if i just do it with a simple cardboard on the side of the ac and a lot aluminium tape, then i make a hole 6" on the cardboard and use 6' duct..

 

[queequeg152]

cardboard is weak and shitty. thats my only issue with it.

it wont last long, but if you are skillful with it, there is no reason why it wont work.

the only thing that i am afraid of is cutting away the plastic housing that is interfering with smooth air flow i dont want to destroy it..

then dont do it.
just know that you would get better results with more agressive modification. removing the plastic housing material before cutting is what i would reccomend... but its never straightforward dismantling cheap disposable goods. a great deal of finesse is often required.

if it does not work to your satisfaction, then it might be something to explore later on.

i will talk to the technical support about removing the side plastic thank you verry much my friend for the help i let you know about what i did..
