Still working on best fan positions. The duct work from window with fans did not really help much. But at least I got to try it without spending the 140 dollars.

So still looking at options. The evaporation cooling looks like my humidity will be to high for me to get maximum effect, so I need to find other options.

1 duct push pull

so window- fan(push>) -duct- fan(pull>)- miners ---------high fan in wall { pull }> out side

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> air flow

those ducts are far from the window. 2 fans in push- pull may keep speed and air pressure higher

Here is a picture of homemade duct work for 24 inch fans. They do make proper duct work for around 70 dollars each. It is made out of lighter material, and it does have a structure to keep it open. Mine is kept open by mostly using fan air, and also using a string holding the end of it up. Between the two it allows the fan's to be by windows and push air through these home made duct's. Still working to see what best fan set up is.

Here is a view closer to the inside of one of the two:

Still playing around with the area to see what is best. I will have some pictures uploaded later tonight of my tarp ductwork.

It saved me around 140 dollars to use tarps I had laying around compared to the duct work I linked earlier.

Well a sucess I basically made 70+ dollar duct work - http://www.homedepot.com/p/MaxxAir-Flexible-Collapsible-Duct-for-Pro-Series-BF24TFORGPRO-and-BF30DDORGPRO-XXBF2430DUCT/205088387 out of tarps. I need to take pictures.

Going to test it and see how it does with heat early next week should get some 80's temps so good testing conditions as far as summer.

I am happy to save 140 dollars with tarps and electrical tape.

I am looking forward to results on this..

power used with fans on at 80f. room temp with fans on at 80 f---------also gear temps-------gear fan speeds

vs

power used with fans off at 80 f . room temp with fans on at 80 f-----------also gear temps-----gear fan speeds

Little bit of random pictures that I have not posted yet. One I suggest even if working with electricity of getting a nice set of non-conductive screw drivers. I'm over cautious

In case you are completely unfamiliar with receptacle box here is what is in the receptacle box.

Needless to say it went well. After I test my tarp duct work and get some pictures to show.

Please document it. Possibly some Youtube vids DIY etc if you have time. Be very interesting to see if you can get it cool enough for your units.

Check out Earthship cooling if you have space on the farm to build a root cellar like room you could have the ground do most of the work for you via passive cooling. Just a tube and vent no AC required.

Or this...

Modern version of an Iranian Badgir cooling system where earth exchange and evaporation pre-cool incoming air drawn by a solar chimney.

looks Like a low cost system once the work is done to set it up. other options are reflective bubble wrap inside the attic.

http://www.farmtek.com/farm/supplies/ProductDisplay?catalogId=15052&storeId=10001&langId=-1&division=FarmTek&productId=11835

face silver to the attic roof white at floor. this stuff will stop sun energy from warming the room. can go up very easy.

lowes and home depot have the silver- bubble- silver version.

this is whitepoly-bubbl-silver version. A good power staple gun and it is up quickly.

Not a problem Bicknellski I will be documenting it all. The successes and failures, ultimetly I hope I end up with a good system I didn't have to spend a fortune on. This is more of a working log of what happens. At end I will make a nice and neat version easier to read.

And thanks once again philipma1957 for your advice. That is a interesting idea. I'm hoping I don't have to do something like it but good to know there are options if I need to.

Solar panel and DC air conditioner?

Or Evapo cooling in a few windows running a solar powered pump with batteries. Might save a lot more.

Might be worth it if you are thinking to pay for air conditioning powered on the grid will be a killer.

Wish i could justify solar but with around .095 power including taxes etc. I just cant justify the up front costs. I am on a farm so they did put a lot of electricity to it. I have 100 amp just for area I'm moving my miners into so power is not really a issue assuming I can keep making more then I pay for electricity. I don't plan on using near that much ever.

If I cant get these fan's to work I might look into evapo cooling. Its just kinda out of my wheel house. I'm hoping I can get it done with fans once I find best cooling with them. I just can get a lot more CFM cheaper in regular fans then ac's.

In next few day's I will try to see if I can direct my fan's a little better. I am thinking i can make something like http://www.homedepot.com/p/MaxxAir-Flexible-Collapsible-Duct-for-Pro-Series-BF24TFORGPRO-and-BF30DDORGPRO-XXBF2430DUCT/205088387 out of tarp I have laying around so I will at least give it a try.

How much energy are you drawing on cooling with fans for all your units?

Costs?

I need to put a kill-a-watt to it. I know it's less then a 110 breaker. But have not got numbers yet.

I just am wanting out of where I had them as it would have had to use AC to cool. Once I get it all set up I will get some power readings.

As far as options I am pretty open. I don't know on evaporation unit it is not a common cooling used here, I have yet to deal with one. I am trying to not cut holes or modify it a ton as far as building. I would like it to be able to one day when I don't mine seem un-touched.

Any ability to do a wall / window evapo cooling like in a big mining operation?

They make a perfect duct for my two big fans - http://www.homedepot.com/p/MaxxAir-Flexible-Collapsible-Duct-for-Pro-Series-BF24TFORGPRO-and-BF30DDORGPRO-XXBF2430DUCT/205088387

I'm hoping i can make something though and save the 60 each. I have some tarps I'm thinking might be able to turn into something like it.

To pull in your cold air you need to be right next to the window .

you may need a shroud . A simple test is use

http://www.homedepot.com/p/The-Home-Depot-Heavy-Duty-Extra-Large-Box-HDXLBOX/205512613#specifications

it is 22 by 22 not sure if that fan is 24 or 36

but that box can use flaps fully out and attach to the frame on 1 window with duct tape and the other end can get really next to the fan.

If this works you can a) just use the box as it is cheap and easy or b) build a wooden shroud to direct the air from the window to the fan

I moved one fan closer to one window. Once all of them are in there I have an attic fan I'm using with other miners I can put next to other window.

It's kinda a lot of testing and seeing results.

S4 fan replacement is done. Still not quite 100 percent happy on fan setup. I most likely will see what changes happen when fans move around.

Tomorrow I should get my S4 replacement fan. I will document putting it in. I'm hoping just plug in and work but we will see.

After that later in the week will continue the rest of wiring. 4 110's and 1 240 to go. Almost half way there.
