Water cooled COB Build/pic heavy

On the diagram, It serves as storage for the system and to keep the chiller from short cycling. In the drawing, you'll notice the adiabatic cooler. During the cooler months, I'll use that unit and the res as storage for cooling pre-lights on.

I noticed that it seemed to have both hot and cold side circuits going into it? Am I reading it wrong?

@ttystik How's it going brother? Been a while.

@ttystikk OUCH, I see your still battling! FUCK EM! Hire good counsel..AND NEVER STOP GROWING!

Already did, and that's one reason it's taking so long.

Supposedly I can still grow, I just can't partake. How fucked up is that?!

You may see it but I don't see the point in any of this. That metal is thicker than a bowl of oatmeal.

In reference to what thickness? There's a lot of metal going on here.

WOW! Fuckin amazing! This country is so young. We have some things to learn here, yet. Shit is being ran like a 6th grade PE class. so yes the heat and cooling dump into the same res. I don't quite under stand the physics principals of hydronic seperation, thermal dynamics's,and computational fluid dynamics, but, I'm getting there.

And here is the more current drawing. The chiller loop runs independent of the light and dehumidifier loop in mine, however, so that I can balance the system GPM better and run the cooling loop independent of the light loop. I'm not using air handlers like you. The lights will do all the sensible cooling and the dehumidifier will take care of the latent heat.

What's the difference between a water cooled dehumidifier and an air handler that also dehumidifies?

Serious question...

The hot and cold in the same reservoir sounds like a recipe for working against itself for no good reason, but I'm not an HVAC tech.

My 5 Ton chiller is also a dual circuit unit but the two circuits never interact. The hot stays hot and heats spaces and domestic hot water and the cold side serves the aforementioned water cooled air handlers- and air conditions my house.

Typically an electric reheat or hydronic reheat option.

I think my colors on my PID drawing are confusing you a lil. There is no actual hot water in that drawing. Only water that is either supply or return. I may try to pull 2 different temps off my tank depending on what I use for a res. An 80 gl storage tank are anywhere from 1000-3700$! fuck me its a pressurized vessel! well depending on how you use it. = head pressure... Im thinking an insulated IBC tote..I've drawn this shit up a gazillion different ways

The idea with a chilled water dehumidifier is to not alter the temp of the air but still remove the humidity. Latent vs Sensible heat. I'll have all the sensible cooling I need with the lights but that water won't be cold enough to condense on the fixtures with the fans running. ( not hypothetical, already tested, 55-60f dry bulb seems about money for an 80f wet bulb room and no condensation on the fixture. Now dehumidifier on the other hand....shit!!! 35-40F and it would crush! So I am looking at various ways to use mixing valves and piping to achieve to zones of cooling temp. I thought about getting an inverter chiller and almost pulled the trigger on it but I found this chiller on Craigslist for 4K in nice condition and low hours. People don't chill there houses around here that often which really fucks up the costs for things like reverse cycle chillers that european and asian country's have access to. We get stuck with single stage scroll compressors that are terribly inefficient when compared to the new bad bay inverter chillers and the Copeland Digital Scroll compressor chiller. Those things are top shelf. But @ 3k/per ton of cooling, hardly logical and a long ROI

This sounds like a water-cooled chiller.Yeah? If so, what is done with the extra heat when DOM hot water isn't needed and its summer so no heating is needed?

Indeed. The two need not be in the same unit, however. Adding heat to the space can be done anywhere in it within reason.

Hot water baseboard heaters can therefore be called 'dehumidifiers'.

It's a chiller, not sure what you mean by water cooled?

My unit has the evaporator coil in a water reservoir which adsorbs heat. The R410a is then compressed and sent first to a compressor coil in a second reservoir where it then rejects heat. The circuit continues from there to another refrigerant to air radiator section where it rejects any heat the water didn't absorb. Think of it as an AC unit with both hot and cold side radiators in a water bath and you've got the picture.

Excess heat is rejected to outside atmosphere, just like an AC unit.

I went back and looked again and yes, that was the issue. I have a dual circuit chiller with a true hot water side and your units are single circuit cooling. My bad!

Technically no.
Without the air-conditioning, regardless of using water or refrigerant to extract the latent heat, the base board would not remove moisture on its own. Now the air handlers are on the other hand are dehumidifiers. But they blow out cold air. In theory, too much for me. Time will tell. I love experimenting. I see your a fan as well.

I've got a 60 of these 12' bars without bungs if you need to help get going again. Let me know. I got other shit too...Panels, Ballasts, chips, Just some rando's. Did they grab everything or just the goods? Still got your gear? I know you were pretty built in... Damn Shame...Motherfuckers

Which unit did/do you have? I saw a couple units like that, but most were chinese rebranders with no customer support....or 15k

You have an air-cooled chiller with a heat recovery loop..... Good research. highly efficient way to go.

Any meteorologist will tell you that adding heat reduces RH by definition. Remember, it's called 'relative' humidity for a reason, and that's because it's relative to temperature; raise temps and RH falls, every time, no moisture removal required.

The moisture removal only becomes necessary when you want to maintain or reduce both RH and temperature at the same time.

Thanks.
That was the whole point of my research project; to improve the efficiency of growing indoors by all means necessary.
