Homemade Portable Air Conditioner DIY - Coldest One Yet! 

How much would you sell this for ?

Copper tubing i think would work better.

Seal up the gores.

If I use this cooler directly into a computer case, will it cause condensation? Is there a way to mitigate condensation to help cool a desktop PC?

All you did was copy TKOR you clown

make & do lol handy tip that one . Haaaaa cheers .

I can't imagine the ice would stay ice long enough to do much

make & do Thank you... I’ve never used dried ice before... I doubt I would . 🕉 namaste

lol

if you use dry ice for this, you are one stupid ass

That's what I was think. Bags of ice would just be a lot of money to spend

Ernie Villa:You done made me thirsty

Thanks mate. Good idea.

You are living in 2046 sir 🍻

@@gibster9624 But if you're making your own ice, you're just making more heat from the fridge motor and the cooler motor. The energy extracted from the water in the freezer is dumped into your house which you then use the ice to cool which nets nothing.

Running duct hose and packing ice around it work better ??

Exactly my questions. Basically how long will it run in a warm room

following

Muster Gwarfield My freezer is already freezing. Cost me nothing to freeze jugs of water, genius.

Muster Gwarfield what people don’t realize about air-conditioners especially “portable“ air-conditioners is that they are incredibly inefficient. Any efficient window air conditioner has all of the parts that create heat sitting outside the window while only the fan is inside the room. But a portable air conditioner has to contain all of the heat generating elements inside the unit itself so we have to depend on hoses sometimes for intake and exhaust. I have seen a few “ductless“ portable air conditioners but I don’t understand much about how those work and if they are efficient or not. I have one portable Solisair air conditioner that I got for $50 from a guy who was moving back up to Oregon, it has served me well but it still causes my electric bill to jump up to about $400 a month in the summer months which is just fucking crazy even with level pay. But I discovered that if I leave a couple of windows open a crack this gives the portable air conditioner new air to work with. My window unit doesn’t need the fresh air, because the heat transfer is taking place outside of my house and so all I get from the fan is the cold air. But you do realize that this gentleman created this unit specifically to use with his vehicle, I suppose if he were to use not dry ice but blue ice packs or gel packs it might last a little bit longer than ice. I’ve got several medical gel packs that stay cold for days because they were used to ship medication to me, those might make this design a little bit more efficient. But I’m just wondering how efficient this design will be to use in a room say, about 20‘ x 20‘?

Social Spit This gentleman has a cargo trailer that he converted into an RV. It is an 8x16 Trailer. After the rear kitchen area and front bathroom are put in, the living space appears to be about 8x10. The hight seems to be only about 7 feet making this space slightly smaller in cubic feet than an 8x9 room in a house. This is the area that this cooler is designed to be used in on weekend excursions. Ice packs may last longer. However, with the reduced surface area of the ice packs, the output temperatures may not be as cold as those shown in the video. The ice melts and the water in the bottom creates more surface are for the air to flow over. This may not make much difference as he mentions using ice in the bottom of his previous build in the video. But, it may add to the overall cooling of the output air. D.

that's what I did. Also the 130 cfm fan, not 300. Also having the aluminum tube under the water/ice, without the air coming in contact with the water/ice....thus NOT a swamp cooler. (no additional moisture.

😂

That was my thoughts too 😂

And did it work?

put a damper in the duct ?

,funny I was just thinking about how I have that same blower and a DC speed controller already wired up to it I was gonna use for something else but didn't. Now I know what I'm using it for.

I love the Larry the Cable Guy AC. PU version.

Hilarious 😂

Yep.

That’s gd brilliant 👍🏼👍🏼👍🏼👍🏼

Get a camper shell on a truck and plum through the back glass from the seat and survive the summer in your truck rent free. Basicaly 2-4 bucks a day or night depending on how long it last

I like this idea of ice and salt. We are making our own a/c and will try your idea.

@@kathleenfoster8552 - good luck with your attempt. The short coming of ice based system is keeping the ice/water cold. Ever though about evaporative cooling?

@OnlyGod MayCommandMe you beat me to it🤣

😂

You can get a hi , med , low switch an a fan out of a car at a scrap yard an if you use a yeti then salt the ice

Learn to fix you A/C and you car boat mechanical electrical electronics takes some effort but will save you 100 of thousands in your life time .

I was thinking that too I think that if they would have that same cooler out of expensive yeti or something like that with thicker walls but I find it would be really hard be cutting and drilling holes into the expensive cooler like that.

Dry ice will expose you to carbon dioxide

Instead of blowing air in? Let the fan blow it out? Got it👍😎 Air being forced in? Goes over the ice. Then is forced out to cool the outside air. As long as you have air flow going out of the room too. Crack a window open. Sounds a lot better! 😜

@@FelipeGomez-vx2sx Yes. And this would help dehumidify, right?

Make a video about it. Help everyone with a visual learning get a better understanding what you're talking about thank you.

Prob wouldn't get the rapid expansion you're looking for with a fan, I get what your saying though

Good point, especially I you container was seal tight from the start.

Why? Please explain the science behind it . Thanks

The intake is sucking in hot air, (for this example lets say from the north) and the out duct is blowing out cold air (to the north), so you have created a cycle of air that is just blowing the already cooled air back into the intake to be cooled again, this won't make the air get colder and colder at an efficient rate, instead at best it will just keep your ice slightly colder for longer lol, you want your cooling duct to be blowing (south)....away from the intake so it can fill the room/car with cold air. Ideally, the intake should be as high up as possible so it is sucking in the already risen hot air and your cold output duct as low as possible so you don't end up with a useless cycle of air as already mentioned. One better would be to have one more duct and fan on it's own, set it high up in the room/car so it's sucking the hot air from high up and pumping it out of a window, i would make sure the inline fan was positioned outside though so the extra motor doesn't add heat to the room/car, this is the reason air cons are so effective because they suck out the hot air of the room which makes any cold air you put in way more effective.

Dehumidifier would end up adding heat since it works by condensation. This would have a latent heat effect, but in reverse since condensation is the reverse of evaporation which has a latent cooling effect. Not to mention the electricity used eventually just turns into heat anyway. (A dehumidifier is actually an efficient source of winter heat if you live in a mild/chilly, damp climate, or in spring/fall when you’re experiencing rainy 50F weather) Also, a dehumidifier is basically an air conditioner that doesn’t exhaust the heat outside, it simply recirculates it in the room. You’re better off just using A/C.

What happens if you use dry ice?

@@Viltgance1 Dry ice is carbon dioxide. Too much of it in an enclosed area will suffocate any animals (including your pets, your children, and you).

@@Uejji holy shit! Good to know, thanks.

Very Wise 4u2 suggest we use frozen water bottles for reuse,recycle, refill to refine😂Ty

Replenish 😉

He does say early on that it's technically not an air conditioner, but an air cooler.

Average air conditioners are basically plain air coolers. The dehumidifying effect comes along with the cooling effect provided that air at lower temperatures have lower relative humidity. As the air flows through your AC unit it gets rid of part of the water just because it looses the power to carry water vapour and this is due to energy loss as overall temperature drops. So, yeah, this thing is kind of an air conditioner.

@@alexismarcane8491 Dryer air makes you feel cooler. When sweat evaporates, it has a cooling effect.

As Alexis said, yes, it does dehumidify the air.

Alexis Marcané this is not in any way like an air conditioner!!! AC removes moisture causing temp to drop. This adds moisture that will cause mold to grow and stink up the car.

My buddy just explained to me wut ur saying here so that I could visualize it, and yeah, this is a much more effective idea

Just cut holes in the insulated bag only where necessary for best insulating effect.

You smart AF bro. HVAC INSTALLER here and I didnt even think of that.

Thanks for this suggestion, I'm probably going to implement. Can you confirm the temperature will drop down to the same amount?

Can you please draw me a picture? Lol I want to do this but I'm having trouble understanding

Got link?

@@mq4oneseventyeight567 yes but I put in all the work and don't feel like sharing. Happy hunting.

Blow vs suck. Ha ha ha

Did you ever finish it? I live in Australia as well, but I worry that something like this will increase the humidity which is pretty bad already near the coast.

A fan that is sucking moist air will rust and die sooner.

u dont

Did it work?

@@underdogtv2855 Yes, it worked much better.

@@hikerboater so will it cool the boat cabin off ate nigth so u can sleep in comfort

I might add a regulator on the blower to control the output and also conserve ice.

LOL damn, I guess it works no matter what is attached to it lol

Have you constructed this yourself to prove your data correct or incorrect? He built his and real world tested it.

What about adding salt to the ice.

You're using the same machine that's constantly keeping heat dissipated, when it gets down to a certain temperature, the energy requirement goes down, but yes you're still technically correct, the issue is are you routing the heat out of the house, is the freezer keeping things cold to the point it only kicks on to disperse enough heat to keep things where they're at, is the internal insulation thick and well designed enough? There are a multitude of variables to consider here, but if you're using this to cool another room, you will get a measurable difference in the room you want to work on.

Yr Genius!👍

Did you have any issue with the jars cracking?

Jars take away the surface area for the ice to cool the air. Direct contact is the way to go

@@TreyPerryWx That's why I said medium sized, enough to double stack. Also since the jars will allow for 0*F temperature instead of 32*F, the loss in surface area will not be sufficient to prevent further cooling.

kyzercube, I know you can get the temperature of water down low when you add salt in solution mixed with ice. I'll have to try your suggestion of salting the ice. I don't care about the mess of melted ice.....it's a cooler with a drain plug. I'm not buying what you said about the exposed surface area of ice not making a difference. Crushed ice cools liquids faster because there is more area and over time that means colder faster. Mason jars are a hassle. The lids will begin rusting over time and that isn't good. The risk of breakage would be an unneeded burden. The set up as shown in the video is rugged and simple.

How would you get it to freeze if its salted? Would a regular home fridge freezer be enough?

Can you post a link with instructions please! I’m not at all Davy on how to do any if this but I need to make one for my 70 year old wife!!

If you are using one of these at home and using ice from your ice-machine, then you won't actually cool your home, since the ice-machine is just taking the heat from the water(to make it ice), and dispensing the heat in your home. Your home will actually be warmer if you are doing this, since the fridge needs electricity to work, and no machine is 100% efficient... some of that electricity will actually become heat.

hours ?? minutes lol

I've heard a few hours. I'd use water frozen in containers to stop humidity from entering your home.

@@ksks6802 That what i was thinking instead of buying ice, get some water bottles and freeze them and reuse them instead of buying ice all the time

It will only add as much moisture as the outflowing air can hold. How much is that? It depends of the temperature of the air.

@@altha-rf1et That will reduce its efficiency.

@@Xanthopteryx it depends on where they live. If your rockn a swap cooler then open ice. If your in a dry climate using this method in conjunction with your central AC then enclosed frozen water. I'm not going into why. Google it.

Get a power station, I use my jackery 1000 for my camping frig and connect this unit together. No need to leave car on while taking a lunch break in my car

Yes, What marine 120v motor for the home would be good?

@@iammaximus614 you could use a 12V wall wart power supply that you plug into the wall. Similar to a laptop cord but 12V output. Not hard to find.

@Kevin Anderson I enjoy central air at my home, too. But when I'm on the lake in my boat, this device could be a pretty sweet way to stay cool.

Did you misspell alcohol? If you misspelled alcohol, I don't know if I trust your advice.

Oh demon alcohol sad memories I can’t recall! - the Kinks. It wouldn’t hurt to try this though,

Use frozen gallon water jugs. Last longer than ice

Paul Andrew Mitchell lower fan speed will actually cool better as it allows for more contact with the ice

That are 15 words

@@Engineer9736 THAT'S

Solar panels are worthless and inefficient

I was thinking of 2 idea's 1 a container to put water in and 2 a Plastic hose that comes with a condensate pump that runs into the river you would need a filter to keep out trash and debris like on a refrigerator

@@craigschray4486 a panel the size of the lid would easily power this, also if its hot its probably because the sun is out so it will be powering the system. hater.
