Homemade AC Air Cooler! DIY Air Cooler! (compact!) - No added humidity! - Easy DIY - Air Conditioner

Do you think this would work for an enclosed go-kart?

You may not need the ice packs as much if you add some salt to the water and pump the saltwater through the coils.

What would be the advantage of having a faster pump?

Can we use liquid coolant?

Thank you for sharing your time and these encouraging results. I had this same heater core based idea cross my mind over the past couple of years, after watching a video featuring a cold copper coil zip-tied onto a box fan. I knew we could do more efficiently. You have given me confidence now to actually spend money on my own compact design without worry. I propose a version that has the coolant sealed inside a vessel that can fit fountain pump in the opening, like a half gallon mason jar, or something. I also propose using cheap vodka instead of water. The Russians historically used vodka as a superior coolant in some of their older military aircraft. This way you could drop the vessel into the bucket without needing to worry about priming the system before each use. Thanks again

Where did you get them metal vents from where the square fan is attached to ?

how about puting dry ice in water or a container then into water

I’m thinking of trying this in conjunction with a chiller. It’s too bad glycol chillers used in fermentation are so expensive, but hydroponic garden water chillers are a little cheaper. Im trying to build a system to cool three heat sinks and a radiator for air cooling and spot cooling on the heat sinks that get pretty hot.

New SUB'SCRIBER from CAVITE Phillipines done please

Why not just buy a water chiller, pump, and an insulated resovoir tank (like a cold plunge setup? A 1/2hp chiller can easily cool 50 gallons down down into the low 40's...of course you would need to run tubing to your heat exchangers, but that is exactly how a highrise building is air conditioned...chilled water. Its really quite efficient too.

Or just put blue ice in rez

If it is soooo cold where is the condensation?

How do you create the fins for one?

What if you had a mini freezer with 3 holes drilled at the top one for the pump power cord and the other two for coolant feed and return.

The internal radiator then sits in a shallow or deep bath of chilled anti freeze.

The tubes run out and feed the external radiators that have fans attached.

This way, the coolant lasts significantly longer would it not?

Holy shit this is perfect for a grow tent

I remember these ACs back when the ACs were barely coming out.🤣🤣🤣😂 I'd find them in old shops as a kid.

The setup looks very simple but is there any guide how to connect the parts up please? I totally dono about electric works but I need a small aircon for my pet that doesn't humidify the air surrounding. To confirm, this does not humidify the air right?

How about compressor free absorption type refrigerator and air-conditioning using induction as heat source, they are starting to discontinue 3 way refrigerator in RVs ?

If you live river or lake side, you can use cool bottom water for cooling too.... or water from well... no need for ice

I’m new to this stuff but I get the brilliant idea of how this works. Quick question, so the same water that runs into the bucket is the same one that goes into the cooler? Meaning I wouldn’t have to refill this at all right(only the ice)?

Do one with a 45" drum fan!!

Have you run across a concave aluminum radiator (transmission cooler)? Id love placing one in front of a fan that has a convex shape.

get a large terracotta urn, aka "amphora". the seepage through the unglazed ceramic naturally cools the contents to 4C. there are charts around for the actual drop in degrees for every unit of water lost. if you have 200 odd litres of water held at 4C, you arent going to warm it up much with this set up! all about thermal mass too. its not as limited as the swamp cooler is, still works in high humidity. though of course, its better when its dry...

and yeah, enclose those coolers, all the air through the fan AND the fins. the slower the air through the cooler, the more heat sucked out...

Why not just send the water through a coil, placed inside an old mini fridge? We have several of them laying around, and none our kids went to college. The things just keep appearing every so often. Set he fridge on its coldest setting lay as much hose inside as you can fit, and trickle the water through it, instead of messing around with ice and stuff. Better yet, add some antifreeze to the mix, and stuff the freezer portion with hose. Make sense?

The only trouble with the systems, mine and yours, is what to do with the condensation. I live in a VERY humid place. Any air blown across a cool or cold coil will immediately create condensation, which is a good thing, as it removes the moisture from the air, but a collection system will have to be made and, either,monitored, or attached to some kind of float switch, to shut the unit off when the condensate reservoir gets full.

How long does it stay cool? Before the ambient temperature affects the system?

How many degrees is it cooling the room off?

I made that exact same thing years ago for my backhoe.

You should run the water in the bottom and out the top to avoid bubbles. It seems to work well, anyway. Nicely done!

Have you ever done a dog cooling bed? chilled iced water through a tube snaked under the bed floor to keep the dogs cool as they lay down? Or a cooling vest for people to wear the same way?

this dude literally is a genius

cool idea bro,keepm coming....😃👍

You must have 0% humidity. I’ve run a similar set up but reversed. I submerged my heat exchanger in ice water and pumped air through the coil so that my buddy could have some a/c in his gutted civic. But we have near 100% humidity here so it caused condensation to occur and the air would occasionally spit some water as well.

Oh hey look, an intercooler for a car in your home!

Need me a water ice jacket to think about this build. 3.99 for ice pack.

mix some alcohol in the water to lower the cooling ..lo

can this be scaled up, using a used car radiator from a junkyard?

This....but with EV car's AC compressor.

If you added some housing around the radiator i bet it would work even better

But dont make ice in the same room. When you are making ice the freezer will produce heat and when you sum heat produced by the freezer and cold produced by your cooler you will realize that you are not cooling the room.

How much did the coils cost?

Why doesn’t this add humidity? You’ve got a literal bucket of ice turning into water in your house, surely this adds humidity? If you moved the cooler outside then I would agree

what if you could use car a/c recharge for the refrigerant?

May I ask where you buy the parts?

You’re just borrowing btus from your fridge. In my slum people just drink cold beer, thus placing the btus in their gut.

What do you do about all the condensation dripping everywhere?

This video is over a year old, so I’m hoping that you see my question.

So the pump, so you just drop the entire thing in the water (wires and all) or am I missing something?

คุณเคยลองผสมน้ำแข็งกับเกลือหรือไม่?

How many watts is the 12v fan ?

IN THE SOUTHWEST, YEARS AGO, EVAPORATIVE COOLING WAS HOT, ON TOP OF THE HOUSE, BUT THE WATER SHORTAGE MAY HAVE STOPPED THAT WITH ZONING LAWS NO INEFFECT TO SAVE WATER

I have even done dry ice and antifreeze on larger scale. Built a unit out of a ice chest….my liquid coolant recipe is still being worked out but it is some ratio of the following: sea salt dissolved in distilled water, antifreeze & vodka. I am still playing with configuration in ice chest but basic premise is a 3 gallon bucket with lid fastened to floor of ice chest with metal mixing bowl filled with either regular ice + rock salt or dry ice depending on the volume of air to be cooled & size of coils. In the lid I have quick release couplers to attach exterior hoses. One of the holes will be for CO2 exhaust from dry ice which absolutely must be vented if camping or in tight space as it could cause loss of consciousness. The other two ports are for the flex hoses that I insulated myself to connect to coil radiators or booster pump station. I also have a power connector on the bucket lid 24V only that way everything can be disconnected and not have to take shit apart. In the bucket I put 2 micro submersible pumps mounted on sides of bucket that turn on automatically if there is liquid even if the main pump isn’t running so that things don’t freeze by chance. Then I have main pump in the ice chest mounted to bottom of chest. Pump is actually very strong and is electronically variable via a couple ways (will go into in a bit). The big pump has a relay lead to manually shut off, automatic emergency shut down and for thermostat. I modified an old ice chest and rebuilt it into a nice looking rugged device that just has ports on outside that are labeled for various hose connections, power, data, etc. so I won’t go into the radiator/fan thing because that depends on your own situation but the idea i had with the main cooling unit is to have all the brains and guts in one place. I am currently working on having battery bank in the unit so that it can run on a charge being I intend it for camping. I am also figuring out what to do about the CO2 exhaust if there should be a pressure sensor inside the unit and a valve to bleed off any gas. So I used a raspberry pi as onboard computer with wifi and Bluetooth. It has a tiny 3.5 in touch screen that I bought as a all in one case but of course the main interface can be accessed on any browser or Remote Desktop service. The Pi monitors everything but the point of it is to maximize efficiency and to act as a smart thermostat by throttling 12v fan speeds (more electricity is wasted when start and stopping vs constant variable) as well as the big daddy variable main pump (boosters if applicable). There are temp sensors on radiator coils, inside of egress/ingress coolant tubes, in front of fan (air temp) as well as inline flow/pressure sensors and coolant liquid level sensors…I also added several sensors that are round discs of absorbent cotton should they get wet it will shut the entire system down and an alarm goes off and if it is connected to wifi it will alert on your phone because it would be horrible if a leak starts and all of coolant pumps out flooding the tent/house or whatever. Anyways I have had many prototypes going back starting 10 years ago so I don’t have a final product. I have some finished ones to get an idea of design. It sounds like this is an expensive habit but as long as you know where to buy stuff used and where to find free stuff and trash to recycle. I am an engineer so the #1 step is to put pencil to paper and just start writing down ideas and sketching out some design ideas! Start very loose then start drawing out designs on some graph paper then go to computer to do some drafting, 3D modeling mock-ups with exact numbers shapes and lines, etc. it is easy to change the design in digital form and you can get exact measurements before building or buying the first thing. You can design anything when you know what you are doing with the right tools and software and computer science/coding/it skills. Learning AutoCAD (free open source alternative is called LibreCAD) & Google Sketchup Make (free) will start you on a journey of making a lot of money and solving tomorrow’s problem’s!

I am working on modular design style and way of building underground in-hill tiny home off grid 100% self reliant & sustainable mini homestead with all the technology we are already used to, just more efficiently and healthfully! Stay tuned because you will hear of this project in the next decade. There is a whole team of us all over the world volunteering our time to engineer new technologies and community models that will address the human rights crisis seen all over the world.
