Possible to duct an AC through hoods instead of cool the whole room?

[Drop That Sound]

Going sealed, looking for input, and of course a way around having to buy a mini split. Anyone try it?

I was thinking along the lines of modifying a unit just like a DIY water chiller with a window AC or dehumidifier, but instead of putting the coil into a res, use it as an intercooler and hook it(in the next room) to the intake duct on my 2 1000 hps sealed hoods.

The way I see it the AC would be running weather it was cooling the whole room or just the lights, and either way the room would be about the same temp.. Or would it just constantly waste electricity.?

I am going to air cool and live in a cooler climate so I don't need a larger btu unit from what i understand, also looking at this https://www.amazon.com/CO2Meter-RAD...4&sr=8-17-spons&keywords=c02+controller&psc=1, any suggestions would be cool!

idk what you mean by an interocoler...

inter cooler is a heat exchanger between two compression stages. ive only ever heard is used for multi stage air compressors? oh and cars... but the terminology is wrong for cars...

before you waste any time fucking googleing random bullshit, just do the math.

your 2 lights generate like 6kbtuh. is you ac unit at least 6k?

if not disregard everything and put in some more hours at your day job.

if it is greater than 6kbtuh then post back here.

you will regret it, if you don't have moolah for a ductless, go with a window unit, they are cheap and durable. Just make sure you have an inlet for ambient air and exuast the hot air properly.

with outside air cooled hoods i won't even need ac for half the year running at night is my guess, and ya was planning on 6k. not sure what type of unit yet, I want c02 to be on 100% and not have to cycle it.


lol i suppose figuring this stuff out is my day job.

This is possible if you wanna end up with lots of condensation in your hoods, It's a bad idea I would scratch it.

Yea the condensation was one of my forst thoughts and pretty sure the moist air wouldnt be great fr your bulbs...

Yes! ,,,,

So then I need to pull from a lung room in the wintertime anyway..... Starting to think i should just ditch the ventilation altogether and go with a 1 ton window banger w/ duct box mod..

Still i would rather build a condensate drip catch pan for each hood before i spend a G+ on a ductless AC

Lowering the operating temperature of a bulb is a big no, and you have no idea how much condensation your plan will produce. Black mouldy everything.

Just do like the rest of us, there's a reason we do it that way.

The cool air that comes from an a/c unit is pretty much stripped of moisture, but once it comes into contact with unconditioned air in the duct work you may get some condensation... The main problem I see is.. The unit is conditioning the air based on the temperature around the unit... not inside the ductwork where the heat from the light is.... so it wouldn't be very effective anyways

Ya I could sorta picture it working, hoods wrapped with foam, insulated ducts sucking 30% RH cold air around the bulbs.

I actually have a 400 watt water proof street lamp that is completely sealed and they can operate outside even when its snowing...

hmm now I can see it working even better if you sealed off the whole ceiling like 1 giant hood, with an extra large sheet of glass, and enough room to stuff a few sealed streetlamp fixtures in there and then AC just that area. Same idea basically just more protection. then again the 2 layers of glass would probably drop the yeild back to the same as running passive without c02. Kinda like those double glass water cooled cool tubes. Maybe I'd be better off with those, and use the same AC as a chiller instead. Or add a extra 2 inch tall box frame around the bottom of my hoods with a second glass and just pull ac through there?

What exactly is the problem with using the a/c in the room?

 

[Drop That Sound]

my multi room shed is outside, not a whole lot of room for another unit but willing to make it work if its worth going sealed. From what i hear unless the room is truly sealed with a ductless you won't see the real benefits.. already making a small cab for a diy 30pint dehumidifier chiller, which is the most important to me. i dont want to be running heaters and acs at the same time, might as well move in if i have 2...

I'd like to air cool as well as being sealed so im not using a 1 ton if possible and just 6k or less. Was going to use that little chiller room as the main intake for the lights so it cools the chiller too, on a motorized damper if needed. also to help justify the electric bill i was going to duct the exhaust from the shed to a small car garage and greenhouse to heat them in the fall-spring. maybe it would be better to not air cool with hoods, and use the dampers i have to distribute the hot air from a 12k to where i want it in the same matter?
