Cool idea, literally. cheers.
Glad you liked it!
Agreed!
SIR ,USE CLAY BIG VAS INSTEAD OF THAT PLASTIC BARRELL ,I USED IT AND IT WORK VERY VERY EFFICIENCY
post a video of it!
Ok soon
@@majeedkhan470 great
I'm interested to see how well this works. My ground-source heat pump is plumbed to a 440-foot-deep well. About 83 gallons of circulating water.
And what is the temp of the water coming out?
@@texasprepperprojects 47° F, year 'round. In the winter, the water returning to the well is 36°.
Try it out then!
@@texasprepperprojects The heat pump went on-line in 2008.
It can get the house to 80° in January and keep it below 60° in July. That kind of performance does tend to be expensive at the meter.
Try it!
Great video! I'm glad your initial tests are proving promising. I'm interested to see how future versions perform
Thank you!
I always love the videos you seem as if your getting burnt out with this all i hope you dont quit making content i truely love to watch and learn i truely wish i could send you a package for future videos im not the company that made them im just willing to invest in your channel and watch you grow so youtube can actually start paying you a decent wage
buy me a coffee or send me an email and we can work something out!
I would I can't find your email and ehats your patreon ill buy more then a coffee lol

Very interesting
Thanks!!
Great video
Thanks!
I think this will result in some cooling. Depending on how cool the ground is. The problems you will face is lack of surface area for the cool side limiting how much heat you can exchange. One huge over looked job of traditional air conditioners is de-humidification. Your cooler wont get cold enough to dehumidify so any drop in temperature you archive will be negated by an increase in humidity because there is the same amount of water in a cooler volume of air.
this is a proof of concept. The full system will be an IBC tote with a lot more volume and surface area. I have an idea on how to deal with the condensation. Thanks for the reply!
I'll give you credit to the "concept" but 76-degree air would feel mighty warm to me !!! So how big and deep of a hole would you need to get the room/shed to about 72oF ?
Based on my research, the answer is 'it's complicated'. It depends on the TYPE of soil you have, how DEEP you can get the hole, and how much water you have in the tank. this is a proof of concept. In the real world, the tank should be buried completely with 3-4 feet of dirt on the top of it. I think that 55 gallons per 150sq feet is a decent rule of thumb. In the next, full scale test, i'm going to go deeper, but it will require heavy machinery, not just a guy with a $130 post hole digger and a shovel.
Also put it in context of Texas summers that are 110 to 120F. 75-80F still isnt' great, but its better than 115F
Good stuff...seemed to be a quite a bit of air coming out of the radiator outlet pipe which probably makes it less efficient, maybe a stronger pump would help or priming the radiator from the fill cap first.
The cap is just a plastic plug so I'm sure it's letting air in from the top
Nice project 👍💪, maybe you can put a rol ( 100 meter) under the ground and see what’s that do .
Greetings from 🇳🇱 the Netherlands .
the whole point is that the barrel holds more water than a tube does
I would increase the size of your thermal batteries and and buried tubes that will increase the radiator surface area. You don't need a pump at all. Thermosiphoning will move the warmest water from the top of your battery to the surrounding ground and colder denser water will be drawn into without any power. Mover the inside heat exchanger to the coolest/hottest part or the shed to see where the exchanger will be most effective. The window picks up a lot of heat from the outside and conducts it into the room. I'd also put it in a roof vent to move the air on the top out.
Themo syphon is super cool, but really slow. Also for it to work, you have to have a BIG temp delta. My $30 pump runs on a $50 solar panel, so I'm good.
I was curious about putting ice in the water early in the day
Don't bother. It won't cool it any more.. just faster. Ice powered AC units are a scam that don't make any sense by thermodynamics
It's not like for like, as on average* (continuous duty) this thermal battery does not have nearly the surface are as a much bigger dig. It has uses for sporadic use where the water can be recharged to cooler temps during non use periods, after it has been warmed up by the daytime exchange. If nights are cool one could recharge the water more rapidly by circulating cold night air into the barrel water. (configure the air source appropriately). Obviously this system , if run continually will eventually heat up the water to some degree (lol) and partially the surrounding earth.
Yes this is what I have told my test people. It will 'run' during the day and then need to be shut off at night to 'recharge' unless you have a HUGE volume of water. This is a proof of concept to learn what I don't know before going to a larger scale
I truely wish i could send you a sand battery and a solar system so you could crank out more content with alit less work each videovtakes sooooo long to produce then edit and everything
thanks!
100 meter thyleen under ground
not with hand tools
this could go anywhere in the room, it would not need to cover your window. I may actually be more efficient not in the window. The reason is your actual exchange of heat takes place in the barrel.
The window is just to pass the hoses
I said a 50 gal 10-30 ft down with alcohol mix or propylene.
Do it
Great video, I love watching your videos! 73.
Thank you very much!
There's really no reason to put this on a window, it should be totally inside, you are losing a lot of potential cooling by using the external air and not recirculating the internal air through the radiator.
well, the air IS re circulating. The glass of the window is closed behind the radiator. 7:51
But it is cool and relaxing to have a view, that is one of the reason of a window, sunlight isnt bad!
