Also M1XW311, when you say "chiller," do you mean a real chiller? You're not refering to an Evaporative Cooler [aka swamp cooler], right? And the hot air coming out of the dehums stays in the room rather than being vented out of the room? -Granger

M1XW311,
1. Are you running a sealed room? Door shut?
2. Do you have standing water in the room from runoff or any other source?
3. Are your dehums and AC [chiller] running 24-7?
4. What are the AC and dehums set at?
5. You're running 3-70 pint dehums all at once?
-granger

1. sealed tent (10x10) - two 1k lights

2. no standing water - coco in smart pots, puts out a lot of moisture apparently.

3. chiller has been running 24/7 since summer hit. no ac, basically cooling the room with chiller in a water cooled setup. chiller is in the next room. chiller has it's own intake and exhaust.

4. temps are set to 85, but has been around 92-94 degrees. dehueys are set to 55%, has been around 59-61%.

5. i'm only running the freidrich right now. using the condensate pump that is part of this dehuey, but need to fix the cheap plastic line they gave me as it leaks. (will run both at lights out as the other one is gravity drain.)

6. its a converted dehuey chiller. no evap chiller. that will not work as the relative humidity in my area is close to 100% year around. also have a 1/2 hp chiller connected from ecoplus which was a huge waste of money, but helps cool at least.

i need one of two things, a better chiller, or better dehuey.

the hi humidity is a symptom of the DIY chiller prob.
with those temps I'd ditch it and get an inline fan and vent the hoods out of the tent
everything else should fall in line.

i'm sure it's more of a sealed room/tent problem than anything.

when it's colder, the humidity is lower, actually condenses on the coolers due to dew point.

reason i say your chiller is the prob is your 90F+temps you don't seem to be able to control..
over 90f and your plants are transpiring very heavily, do you water 2x's a day?
sealed running C02 mid 80s and lots of air circulation is great for veg and 1st 2-3wks of bloom.
veg'in plants explode under those conditions but in bloom you get mucho probs.

anyways thinking about the temps now that your telling me about the condensation on the chiller,
get a 10 degree difference and water starts condensing out of the air onto to everything
like your chiller,
if thats dripping wet it'll be kind of like a mini humidifier.

it's sounding like you have little to no control over temps.
where's the location of your tent?
sounds like it's in an attic?
tents are crap for insulation value.
with a tent you need to have some control over temp/envir. conditions outside the tent.


>>>>>>>>>>>>>>>>>>get your temps in the tent under control and everything else will fall into place<<<<<<<<<<<<<<<<<<<<

half HP? thats nothing. each kw of ligting alone produces more than 3.4kbtuh.

a half HP comes out to what... 1500btuh? assuming its actually half hp...

If your worried about the extra heat the pump out, you can always duct the exhaust and pump it out of the tent. Just sayin'

Not sure what you're saying. If you're talking about exhausting the hot air that comes out of the dehum, no workie. The hot air is the dehumidified air. -granger

the tent is in a room inside of an air conditioned area. the heat is actually transferring through it, which is okay as the building's AC turn's on periodically, keeping me comfortable lol.

the 1/2 hp chiller is working in conjunction to another home-made chiller. as i mentioned before, the extra heat from the dehuey is making the chiller work extra hard.

at least i have an extra dehuey for when i cut down later this month. i'm getting one of those super efficient dehuey's next month and will let you guys know. we're going in full circle...

before thowing another 4 grand at something, just take a deep breath... slow down here and think this all through.

do the math here... btu's in and btus out.

is it cheaper to remove more btu's, or generate less btu's? chillers tend to be way more expensive ton for ton when compared to forced air hvac units.

perhaps consider a split 3 ton goodman... 3 grand.
will remove 36kbtuh from your room, and will remove huge amounts of water provided it does not short cycle. 36kbtuh is what...9 maby 10 lights?

you can get better dehumidification with an ECM blower air handler... slowing the air flow so as to achieve a greater temp drop across the coil.

it amazes me how much money you folks have to throw around... 4k is like half a semesters tuition.

what at the details of this DIY chiller? any pics or build logs or what ever?

one of the reasons i got a refrigerant license and spent time learning was to build mini chillers to support another area of interest... im curious to see what you built here.

just a converted dehumidifier. not very pretty so i'm not getting into that lol.

but like i said, the dehumidifier in the tent adds 10 degrees, and my chilling setup can't cope.

i'm looking into how loud the outside part of a minisplit is. this is a concern to me.

not sure where the 4k cost came from, the efficient dehuey was less than 2k my cost.

you are right. not sure where i saw 4k.

the ultra aire 105xt or what ever the model number is, is like 2700. same unit just with duct adapters. interesting.

minisplits tend to have some of the quietest condensing units period... however they are costly ton for ton. they also have pitifully weak blowers, part of the reason why they are more efficient.

a conventional split unit will tend to be louder, however with a conventional split system, you get a good air handler that can produce enough static pressure to operate media air cleaners, photocatalytic oxidation cleaners etc. id go this rout personally, however if you are not mechanically inclined the mini split will be far far easier to install.

minisplit is a great idea for the cost. would be great for the sealed tent. would drop temps to 85 degrees easily. pretty damn efficient too.

i used to do residential electrical work, so install won't be a problem. just need to get a AC buddy to run the freon. (everyone works for nugs, at least my friends lol)
