Finally finished my custom cab and installed the exhaust.. the paint got a little chipped while moving it in. It looks like I'm growing weed lol.  Grin My dog got his head stuck in the air intake rofl. It was so funny, but I thought he was going to break it.

I live in a rental, so I'm afraid Geothermal is just not practical for me.  Sad

I should be able to post pictures and explain how my ventilation works in a week or so! I think it will be pretty unique, I haven't seen anything like it on here.

You may have one of the more difficult environments to do cost effective environmental conditioning. Looking forward to it Smiley

Most American home has a nice backyard right? I'm not from America but dont see digging your own yard can be costly. Rent a tool and take a day to dig?

If space is not available you can use water-water exchangers and heat a pond, a pool or household hot water.

need a big back yard. my 3 1/2 ton geothermal system has 2000 feet of pipe buried 5 feet down in the back yard (horizontal loop). you could rent a back hoe to dig the trench if you want; we hired a contractor.

smaller yards without the room for that amount of pipe will need a well (1, maybe 2, possibly more) a few hundred feet deep (vertical loop). THAT you need a contractor for.

You want to know the most efficient way to cool a system? Use mother earth energy, .... thermal energy ( Use geothermal heat dump)

Geothermal has been around for many years and is efficient however expensive solution.

I like this little youtube video.

Geothermal solutions


LOL good job on searching.

Now start digging more. Its not that expensive if you're looking to cool thousands of watts for free.


I have already lead project installations using this method in the recent past. At that time they were for normal residential use and it was not cheep.

What I hope to see is what others bring to this show and tell... Ghetto style Smiley

Bitcoin project is global, and its mining participants are part of this global network. So it goes with out saying that not all seasons and environments are equal on a global scale.

With that said why not show an example of your setup? I am sure people that frequent the forum would like to see it.

This has been covered so many times( Back then when we still have ppl with knowledge like D&T)

Actually, what I am setting up has not been done before here on bitcointalk, I guarantee you that. So you to think that you're some expert on why or why not my setup will work or not is blasphemous.

I'm shocked when a terrible idea takes 2 pages on this forums.

Can you not read? I am not using OPs idea, for the 10th time.

I doubt that you could even explain to me how I plan to set up my system, so how can you say that it will not work?

It's not about the most efficient way for me, it is about the cheapest way. I have almost all of the equipment I'm going to use already laying around.

For one of my sites, (4400 watts GPU power = 13Gh/s) I use this barn fan.



(source link)

It is effective even in summer at maintaining the indoor ambient temperature range between 20-22 degrees Celsius.

This is true if ambient temps outside don't go over 30 Celsius.

Cooling cost usage is at 160-180 watts.

Moving / purging the heated air 3200 CFM alone is rather effective.

If you're simply using air, then remember .... lower volume = more air thro exchangers.

By volume, i mean the volume of the heatsource.

If your plan is to follow the idea of the OP, then you already fail. But i will let you learn the hard way.

Some of you guys must have failed physic terribly in grade school.


Sigh... I have to say it, you are a fucking retard.

Learn to read, god damn. No, I am not using OPs link.

How about you fucking read and pay attention before you start judging others blindly and open your mouth like an idiot.

Leave the conversation here to people who actually read what other people say, kthnx.

The only retard is you who somehow thought you have found a way to cool that 5500watts of yours from this thread.

No problem.. I can be mr grumpy pants sometimes.  Grin

I will show you guys after I get it set up. I will certainly have a cooling system like no one on here has probably used before, so I understand you guys doubting its capabilities. I'll be cooling about 15000 watts by the time the project is completed, using water cooled air intakes and a couple exhaust fans to cool everything (hopefully less than 750 watts of ventilation/cooling if things go as planned.)

I'm still working out the specifics and don't even have all the necessary hardware, I'm probably about a month out from finishing the project. Hoping to reach about 25 Gh for all the hardware, which will be mining alt coins (LTC, etc).

This + my day job = busy month!

Meh.  Have fun with that.  Smiley  What you're describing is is something that already exists in a more efficient form and is used all over the place in desert climates.  Water cooled intakes = an evaporative cooler.  If you use ice with it (like in the original post), you're just blending air conditioning with an evaporative cooler (and still takes a similar amount of power as AC).

I'm currently cooling 33,000 watts of GPUs while using 602 watts or less to cool them (evaporative coolers in the spring/summer, fans in the fall/winter).  It doesn't get much more efficient than that.

...in other words, what was used in the original post is just "reinventing the wheel".  It's a cheap way to make a horribly inefficient evaporative cooler and would work "in a pinch", but it wouldn't work very well for removing a lot of heat effectively.

Can you explain more about your ventilation/cooling setup. Cooling 33,000 watts of GPUs with 602 watts is impressive.

BTW- I added some padding into my 750 watt estimate. Really, all I'll be running is a 360 watt water cooler and 180 watts in exhaust fans, so it should be much lower than that.

annnnnnd I just realized you weren't the OP.   Grin

You're like the 3rd person to say something like that so I suppose I'll respond.

If you'd read the thread, you'd notice that I'm in the process of figuring out my ventilation and cutting down on A/C use....

Thanks for the advice though lol.

well good luck with that then I wouldn't want the extra strain on mine or that high of an electric bill. All I know is from my experience 4000 watts plus another 60 or so amps for a 2 ton central a/c is about $550 a month here and that's at $0.08/kwh

4" exhaust? no way are you crazy? I used 4 walmart box fans, two windows open (one intake one exhaust to cool a little over 4000 watts of gpu's. for 5500 watts you would probably need a 1/8 hp 24" exhaust fan at least, with active cooling you would be looking at a 20000 btu a/c

I'm pretty sure I can make it work. It is running 24x7 stable right now with no exhaust and only a few house fans blowing air over them. The central A/C is doing most of the work.

The only reason I'm adding cooling is so that I can over clock & take a little bit of the load off the central A/C which is running almost 24/7. Temps are getting up to 75-80 though and I don't want to OC unless I can keep temps <75

Well, I'm using a dryer circuit to power everything. So, I have a 4" dryer exhaust right there that would be really handy to use.

It's a rental property, so I'd rather not make any permanent modifications, and there aren't any windows near the the laundry area to put a bigger exhaust fan in.

I'm thinking a 4" exhaust is too little for ~5500 of power in a small enclosed space without something else to help with the temperatures.

I already have the water chiller laying around, so I'm leaning towards a water cooled intake rather than putting in an A/C unit.

Plus, water cooling is more efficient than an A/C, so I technically I will be able to cool more with a smaller power bill.

This is beyond ridiculous, the ice taken out of the fridge needs to be produced and the heat exchanger in it convects the heat into the room.  This is even a net loss in cooling.

Seriously a used AC costs 50bucks on ebay, yes these things consume 2400W, but for a reason.

This seems unnecessarily complex. The surface of the copper pipe exposed to the air is so small that your setup is probably LESS efficient than a fan pointing down to blow air directly on a tray filled with ice water. And this would be a lot simpler to "set up" and less expensive.

This is one of the simple tutorial 7 watt pump power + Fan power 60-150 watt.

Custom made AC unit to cool your systems.

http://www.youtube.com/watch?v=ZF0J8OvDSmM&feature=related

Wouldn't the copper tubing sweat? I'd be scared to get that too close to my rigs.

The chance of the tubing sweating and the fan blowing water and shorting something seems likely.

Or am I wrong?

I ask because this setup would be really perfect for me if it wouldn't sweat. I have a 1/2 HP water chiller sitting around not being used, so I could set up maybe 3 or 4 of these and use the chiller to cool the water.  Cool

Yes the copper tubing would sweat. Open up your home A/C and look at the cooling unit you'll see a water troff and a pipe going outside for the water to drain.

Not only that but your freezer is the same sort of idea as an A/C unit, it cools the air inside it. So your taking heat from the air and using a fan to transfer it to water, then putting water in a freezer to transfer heat back to the air and freezing the water. All the while you have to manually move ice/water around. It just seems anA/C unit would be more efficient... Or a water chiller as you say you have.

I agree, if I was building from scratch I would go with an A/C. Water chillers are expensive.

EDIT- A pool would be ideal for this, you could dissipate a lot of heat especially if you have a pool in a cold climate! You would have the biggest hot tub in town!!!  Cool

Cool, cheap idea but how long does the ice last? And how much energy/time do you use to make it? It may be more efficient just to get a window A/C unit.

That's the thing... as this thing runs, the heat in the air is transferred into the water.

So, after the water warms to the original temperature of the room, it would not cool the air at all.

How long it would take to heat up would depend on the size of the reservoir (it would be ideal to use something much larger than a 5 gallon bucket... think 100+ gallons), whether you use ice or not, and the amount of heat you are trying to dissipate.

I guess it would work OK for smaller setups, but switching out buckets of water and ice often seems a little exhaustive.

The only reason why I'm interested in this solution is that I have ~$1000 water chiller that is just laying around that would be perfect for this.

I guess it would work OK for smaller setups, but switching out buckets of water and ice often seems a little exhaustive.

The only reason why I'm interested in this solution is that I have ~$1000 water chiller that is just laying around that would be perfect for this.

Well, I'm using a dryer circuit to power everything. So, I have a 4" dryer exhaust right there that would be really handy to use.

It's a rental property, so I'd rather not make any permanent modifications, and there aren't any windows near the the laundry area to put a bigger exhaust fan in.

I'm thinking a 4" exhaust is too little for ~5500 of power in a small enclosed space without something else to help with the temperatures.

I already have the water chiller laying around, so I'm leaning towards a water cooled intake rather than putting in an A/C unit.

Plus, water cooling is more efficient than an A/C, so I technically I will be able to cool more with a smaller power bill.

Cool, cheap idea but how long does the ice last? And how much energy/time do you use to make it? It may be more efficient just to get a window A/C unit.

I was planning on using something like this: http://www.hydrogalaxy.com/growing-lights/lighting-accessories/6-ice-box-heat-exchanger/

Your solution would probably be cheaper if I could make it work. But, sometimes I need to leave the house for 5 days a week for work, so I can't stand the risk of coming home to a huge puddle on the floor!

Would that not pose a greater risk if you were to put the equipment directly below the unit? (Gravity)



Well, I already built a sound proof box that is 62" by 32" by 48".

I was thinking of throwing one or two of those on the side as a water cooled intake, so the ice box would probably be about a foot to a foot and a half away from any equipment.

Are you capable of controlling the air moving into and out of the room? Maybe with one of these?



Power usage at about 160-200 watt's at full power 3300-4000 CFM

I'm not sure if the Ice Box sweats much or not, I need to do a little more research on it.

That's not what I wanted to hear!

I live in Texas about 2 1/2 hours from the gulf of mexico. It can get pretty humid here... it usually stay between 42 and 94 percent relative humidity.  Undecided  Cry

EDIT:

Edit: I would try to use this setup to control the air entering the room. However take into consideration the distance you place the unit from your equipment. For added cooling you could double up the cooling pipes as well.

Edit: Remember that ventilation exiting the room is important factor to consider as well.

Good idea, there might be some way I can make it work.

I need to cool about 5500 watts. I was already planning a 4" exhaust fan, add this into the mix and I think that would keep things pretty cool allowing me to over clock a little bit.

Edit: At 5500 Watts I assume you are running that all GPU? So your at about 12GH/s to 14GH/s

Best thing is to try in a test environment first. The airflow over the coils plays a critical role in controlling the Dew Point vs Relative Humidity.

In your environment Relative Humidity is indeed a greater influence on condensation.

This is one of the simple tutorial 7 watt pump power + Fan power 60-150 watt.

Wouldn't the copper tubing sweat? I'd be scared to get that too close to my rigs.

The chance of the tubing sweating and the fan blowing water and shorting something seems likely.

Or am I wrong?

I ask because this setup would be really perfect for me if it wouldn't sweat. I have a 1/2 HP water chiller sitting around not being used, so I could set up maybe 3 or 4 of these and use the chiller to cool the water.  Cool

I suppose it would depend on the humidity in the air and the amount of air flow passing over the pipes.
