You don't need air conditioning anymore!

I made almost free cooling of my workshop with geothermal free energy from the earth.

I cool my entire 5000 square foot off grid home with a system similar to this, and that setup will rain water out of it like crazy from the condensation. You'll want to build a water catch with a drain outside
I love using my resources at home instead of buying everything. I've been living completely off grid strictly on solar energy for over 10 years and love it. I run 2 full sized electric refrigerators, 2 full sized electric deep freezers, a deep well pump, and everything else a normal home has and all without outside power

The title of this video is confusing. It should read: `If you have the well from the movie "The RING", this air conditioning system is for you too!"

In 1982 I rented an apartment in a complex with 600 units that had geothermal cooling & heating.
It was nice, the electric bill was about 1/3 of normal costs.

Nice! Got the fans, got the radiator and pipes. Got the pump. Now I just need the well. Now where to get a well...mmm

[ljprep]

Very nice. Now insulate the inlet hose from the well to the cooler so you don't lose any coolth there. And if you paint the inside of your shop with pure white paint, it will give you twice the light inside that you have now and require 1/4 to 1/2 the amount of LED lighting to make it very bright. I painted the shop floor white, too, and it makes dropped screws easier to find.

I like the video, but lets try to be realistic here' about that last comment you made... A small 5000 BTU A/C is only about 350-500watts. That's all you need for a shed that size. A 3, 000 watt A/C would be overkill.

A/C's have become very efficient over the last decade or so. Other than that, I know it's not really about power-draw and more about sending a message, so still, fantastic video!

Nice solution if you have a well available.

Unfortunately, most people don't.

[Dr_Larken]

So I was trying this on one of our properties, thought I was doing good using the well in the backyard!
Only to find out later on as I was told, we don’t have well ! It was the septic tank!

Very cool I wonder if a single radiator in a buried 55 gallon drum filled w water would do anything

[bryansmith]

The concept is solid, but the straight water through the heater cores will corrode them quickly if they aren’t first plugged by trash in the water from being an open system. Also the condensation on the coils would make a mess in the shop with no drip pan under it. A closed loop system in the well would work better, but antifreeze might leak into the water system eventually.

When I was in high school, I considered building something similar to cool my parents' home. We had an old well to use as a source of cooling. I had planned to use a radiator from an old car and use a box fan to blow air through the chilled radiator. My hangup was finding a pump that would be powerful enough to pump the water up from the well and through the hose connected to the radiator. Another issue was how to best capture and remove the condensation water that would be dripping off of the radiator.

[garrydunkley]

It would work better if you put the indoor unit high up to condition the hottest air ! But nice one,
I have an ac that runs off my solar system so it’s all good 👍

[scubasmitty]

The BEST A/C and heating would be an underground home !!!!

[ronpalmer]

That’s great, all I need now is a similar well in the garden

[mikemotorbike]

It's frustrating watching those pipes get pinched by the lid. Otherwise, congrats, great idea and execution!..But a concern is to assure the groundwater flows fast enough through the well. Pathogens, fungus etc grow in heat. Would a larger rad increase the differential between the incoming and outgoing water? I notice briefly on the thermal image the tubes were almost the same colour coming in as going out. Perhaps another rad outside on the returning pipe to dump the heat before reintroducing the water back into the well? It would be interesting to plot the temperatures, because an exterior rad may actually introduce ambient air heat into the well if the temp is still cool leaving the inside rad.

If you can create a greater difference, you could run your pump and fans less to save money. Of course, a heat pump "water chiller" water to air, might be ideal. Depends on whether the well groundwater flow can remove the heat fast enough, I guess. Your innovation might help a lot pf people, including farmers trying to cool their livestock.

There are air conditioners now that use 200-250 watts. My small window ac uses 400 to 500 depending on outside temperature. If it`s only 80 to 85 outside it runs very efficiently. My June electric bill in subtropical Louisiana was $41. I want one of the 200w models with 8000 btu to use with solar but I can get three 5000 btu ones for what it costs.

Depending on the water corrosion can be an issue. In my area untreated well water eats right through copper . It takes several years and the internal buildup also creates an insulator slowing down the transfer of heat. It's still an awesome idea . One that I still intend to try. 👍.

I like the well as a cold source, but you should consider something to collect condensation at your heat exchanger. If you want to reduce noise you can increase the surface area of your heat exchanger (more radiators) and hang them on the ceiling so the cold air will just drop on you. I myself have a closed loop system at home meaning a heat exchanger 140 m below surface as my cold source with salty water running through it and then through my ceiling to cool us down. It combines very well if you just power it with a solar panel or 2 because when the sun shines you need cooling the most. I keep my ceiling above the dew point to prevent condesation by measuring air temperature and humidity, but for that you need a very large surface area so you have sufficient cooling.

The hose outside the water well should be as short as possible and thermally insulated.👍
