- Homemade AC air cooler! The "Copper Coil" Air Cooler! how to make a non-compressor based DIY air conditioner using a box fan and copper coil. details: copper: Two 20 ft. rolls of 1/4" copper tubing. vinyl tubing: Two 3 to 4 foot sections of 3/8" tubing (OD) 1/4" (ID). pump: 200GPH (from harbor freight). note: the air produced using a "copper coil air cooler" won't typically be quite as cold as the air from an "ice bucket" air cooler (but the volume of air produced is much greater than an ice bucket air cooler produces) so it's a trade-off (more air that's cool vs. less air that's colder)

I made something like this when I was renting out a garage, that was converted into a studio. It worked great. The only difference was i would use a 5 gallon bucket, fill half of it with water and freeze it. Would add enough water to cycle through so it wouldn't melt fast, but also put salt so the ice would get colder. The room would get so cold I had to turn it off.
When will you put the salt to the ice before or after freezing.plz
Did you use the same fan?
@@ch-0162 probably box fans are the best- about $20 at Home Depot
How cold does the room get?
@@islamreminder8538 I would add it after it's frozen.
Best idea I've seen for a budget air conditioner..live in Iran and am going to market it asap!
are you a millionaire now?

God Bless Israel!!!!
did i miss it or did you completely forget to record the pump setup?
It’s a Mandela effect
Cern is jacking around with our reality again. Eventually that excuse will be used in a court of law
It’s just a fish pump in the water connected to 1 end of the hose, then the other end of the hose dumps the water back into the water

Nice work mate, best budget AC i've seen. Makes more sense then the rest.
thanks brother. appreciate it.
Great deal here and thank you for sharing this.
That's awesome, and I have access to all of those things!
great device, will need to try. thanks
I'd like to see a similar experiment just using cold water instead of ice. I'm thinking of building a cooling unit with a tube running under the ground for cooling. Great idea in any case!
It's cold water with ice in the cold water making the cold water colder, thus making the air cooler coming out from the fan.
Great job!!
Wow, it's beautiful.
I just want to say thank you,going to make one today,I'll let you know how it turns out!
I really liked this. One thing I would suggest is to apply pipe dope to the ferroles of the compression coupling for lubrication before you tighten it. The reason being that the friction from tightening can cause a leak.
By the way, the ferroles are the brass rings in the compression coupling that go around the pipe. Just a coat on the outside of the rings and don't be shy with it.
wow you are awesome!! thanks so much!
love it!
cool video! (pun intended xD )
Bad comedy aside i always enjoy watching your videos man.
Keep em coming.
Very nice Man,!!!! Thankz''''''''
Pic at 1:06 shows aquarium pump, along with copper & vinyl tubing, clamps, connector,twist ties etc. If it had fins on the coil from say old pop cans it could be made to work more efficiently.
very cool!
Have hydroponic pump for unit I'm building, was look into using 3/8 in OD copper tubing.
im going to try this with with one or two of the small ad-on transmion coolers you can get cheap
Keep the ice covered to prolong the cooling time and to prevent increase in humidity
Sorry to be off topic but does anyone know a trick to log back into an Instagram account..?
I stupidly forgot my account password. I would love any tricks you can give me
@Cesar Idris I really appreciate your reply. I got to the site on google and im trying it out atm.
Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
The ice will condense water from the air and dry out the room, not the other way around.
Decrease motor speed to prolong cooling time. ☺️
Thanks !
Neat build... Would you say this is working better than the other 2 you made? The evaporative cooling one with the Coolpad Ice and the 20" fan, or the 11gal bucket with 3 holes? For how long did the 10 pounds of ice (even in with no ice chest) allowed you to keep the system in conditions to cool the room (with an airflow below 60~65F)? Thanks much! :)
My GED students at the local jail assembled one of these for my mom recently as she is having a hard time with rising air conditioning costs. They used a box fan, copper coil, the pond pump, vinyl tubing, but used a styrofoam cooler with lid instead of a bucket with open top. Every evening she rotates out two big downy (filled with water) containers frozen from the freezer, 3 ice trays, and one ice pack into the cooler. Also she replaces the water with cold water. It does work and helps her sleep now at night during the summer. Her air conditioning bill has lowered significantly obviously. It really helped. It runs about 6 hours before everything melts and the room is cool all night. Comment below if you have any questions about the details and I’ll answer.
That's awesome and I just started really looking into this stuff recently. I was thinking of using copper tubing for this, but I'll go all out and get a radiator. I'm planning to make this much more efficient while still being able to be done from buying parts from the store. She should incase the cooler in a bigger box with each side having an air filter so she also gets clean air and the cooler gets some help staying cool. I would insulate the walls where possible as well. Also they should continue using the copper tubing going into the cooler. They could make it go around the perimeter helping to evenly cool as well before exiting back in the center. Then besides the pump there would be almost a such space for ice. She should also mix salt in the ice so it stays frozen longer. I might even run this off a solar panel system since I would only need it for when I'm sleeping
I'm actually planning to do this with my fan since there are restrictions with running the window AC in the office.
Hey man great vid just subscribed to your channel. Quick question tho, I live in Houston so the humidity is very high what DIY would you recommend for me the humifier or copper coil? Thanks in advance!
This is great idea,how many HP for the pump de we need? Any? Wow! Its awsome
luv it...
good stuff man subbed you
Thanks for the sub! 😎
Please tell me how long it will work for 5 ltr ice?
Absolutely amazing!
Best ice bucket Bucket challenge yet 😅
amazing :-)
.Woww, the best, sheap, eazy to make cooler & heater on whole CZcams! im gona watch more and make this !
sounds good. i've got lots of air cooler videos on the channel. many different ways to make them.
Thanks
Did not read all comments, but put coils on intake side and cover corners like a fan shroud on a car. This is what central air systems use to get an equal amount on air going past every inch of the coils. Vacuum is always better than blowing at something.
So you're saying the fan sucking the cold off the coils is better than air pushing through coils to transfer cold? Hmm Idk about that one but you did both sides it would def be that much better!!
Is it better to suck cold air rather than push cold air?
@@Lucas-nf7uj Depends on the situation. But in this case Lynn is correct.
@@Lucas-nf7uj it is easier to pull air than it is to push air. Say you have a 10 ft pipe with one blower unit to go on the end. If you have it on the start, it has to push against 10 ft of air. If you have it on the end, it doesn't have the pull 10 ft. It just pulls from right beside itself, creating a low pressure vacuum, which makes the air further back the pipe rush forward to fill.
@@buzzsaw64 that's good to know actually, thank you
Hi, How did you hook up the 1/4 vinyl tube from the copper coil to the the harbor freight 200 GPH pump. They attachment on it isn't a 1/4" and I want the water flow to be as good as possible. Thanks great video!!
How difficult would it be to connect the pump to a heat exchanger, then cool the water with...something else? (Idea not fully formed yet.) If, for instance, one did not have access to ice (for some reason), but still wanted to create a cooling system?
ive got a ten foot by ten foot room, which of your homemade air cooler devices do you recommend for dropping the temperature effectively? The room is usually in the late 80s temperature wise with moderate humidity, and we have a lot of electronics in here that crank up the temperature a bit more. Would any of these work and its more a preference for what I want to build, or is there a specific one you recommend?
This very useful when you go to the desert
This is the exact setup my aunt built for her apartment in Oslo. AC is banned in Norway FYI and is not available to purchase so this is the only way to cool down her bedroom.
great video how long does your block of ice last?
awesome genius
I would like to build one of these, I just have one question. When you made your bends to attach the rubber tubes, did the copper want to kink up on you?
If you lived out in the country you could install a cistern that was deep underground and had an insulated top that keep the water really cool that you could pump out from the very bottom to circulate through a copper coil in front of a fan to cool your home or green house with the return water feed passing through a wrot coil in another cistern to bleed off heat before empting into another cistern that slowly feeds the main cistern your pulling chilled water from to provide cooling to your home or green house. 😊
with your next fan based project you should use a Vornado fan or room circulators as they like to be called, even the little Vornados move a ton of air lol
Vornado uses THE cheapest motors in their fans, but they do honor their warranty. Electric motors should last a very long time. It is very hard to understand why they use such cheap motors.
they cant be the cheapest motors in the world lol i went through 10+ cheap walmart fans in a little over 2 years, ive had the vornado now for 2 years and its probably only been shut off twice, i think they are fantastic little surprisingly strong motors, and yeah the 5 year warranty isnt bad, most of the time when the motor goes "bad" it isnt really bad its just lost its oil over the years but i havent even had any visible oil loss from this little vornado
+1234garrett1993 you got lucky. We bought two even though there were many complaints about the motors. Both motors died. We had to ship them back to get repaired. Vornado sent UPS label, but packaging cost us money. Hope the new motors will last.
Nice
Hey, I checked your channel and I've notice that you have build few cooler's. Which one you conciser the best? Thank you for your answer. Really good job btw.
bboystances I can’t believe it’s been this long with no answer lmaov
How you make the ice water run thru the coil?,thank you
What is the air temp with just the fan and then after the ice water is circulating?
Hey thanks for the video, I made one and now I'm cooling our kitchen with it. Only down side is my wife forgets to add ice throughout the day lol
Your a good guy desertsun02 . Just when I felt like the loneliest man on earth because I thought I was the last nice honorable guy in this world, you prove me wrong. Thank you fom Wll of us to for sharing kindness
Can you tell me if I use a cooler with ice, how long typically will it last? also if i use a strong pedestal fan in my garage in las vegas, can it really cool the garage down?
Hi I thought you should know I put one of your air conditioners to work and it works great, the one you used with a cooler and fan with ice. . I used a little smaller of cooler then you had An aluminum Tube that goes on a dryer and a fan that I ordered that you plug into a USB. The fan plugs into a battery bank that I have that can be charged by solar. so I took 2 gallons of water in gallon jugs froze them, hooked it all up with my battery bank and Wella. what a great idea. My bedroom does not get cool enough so this will help tremendously. Now if I can get and ice maker in case SHTF, I'll be good. Thank you so much for the great idea!!!
Wish I knew about this when I was an undergrad BURNING in my dorm room b/c of end of summer heat.
This is a really great idea. I do a lot of RV camping, and there's often ice available, or can just bring a bunch of ice blocks in a few coolers. I know this depends on the ambient temperature, but about how long does that block of ice last you?
And it's been a bunch of years since you made this, after living with it awhile do you still use and recommend this setup?
hi and thanks! ice can last several hours at a time. big blocks last the longest. yep, i've still got and use it. i recommend all of my projects. which air cooler you make mainly depends on the materials that you have available and your cooling goals. i have boh the ice and non-ice types. in the 13 years that i've been making videos i've only gotten rid of 2 projects (i've still got something like 300 of them in total). the heat exchanger coolers are some of the most powerful air coolers.
nice
Out of all your DIY Air Coolers, which method would u recommend for cooling a small room? Not interested in the swamp cooler method (creates too much humidity).
Geothermal recommendation --- Dig a hole in your yard (a few feet) , drop another coil in it and connect to the indoor coil (using the same plastic tubing) and place that pump in the line permanently. This will force the water down into the ground, cool it off and return the water back to the fan cold. Now you no longer need ice. Create a plastic tray under the fan that drains into a condensate pump and push condensation outdoors and you have permanent air conditioning on demand! Geothermal style, you are welcome!
Uh yeah, thanks..... for nothing. LOL
@@raybbaby why?
Have all the parts by the end of the day Just waiting on my pump copper tubing and ice cooler
how long does it last. 2 hours? 3? Still awesome. any body know how long the ice lasts
do you have condensation around the copper coil ?
could this work in a large 24'x40' greenhouse when it's 95 degrees F.?
it only works in small rooms - it produces about 2000 btu of cooling ---for 24 x40 you need 24000 btu
How and where did you hook up the pump ?
would adding salt to the icewater mixture make it cooler?
How large of a room will this cool? If I need more cooling, will putting a second coil of cooper on the backside help?
you should try to use a yeti bro for maximum duration of cold water flowing thru the coils?
My car’s ac vents blow somewhat warm air. Do you guys think this would work effectively if I installed the copper on my vents?
What are you using to circulate the water through your coil?
what size adjustable clamps did he use?
For anyone interested u can buy a condensate pump at ac supply houses comes with the vinly tubing that fits 3/8 size line like he is using use a hose clap or medium zip ties
Thanks for the example you set of fabricating useable devices. I wanted to ask if the cooling efficiency is different with coils in front of the fan air flow or in the rear of the airflow? thanks again, I have too do more projects with my son of this sort. I have been to some 3rd world countries where this resourcefulness is the difference in survival and comfort, thanks....
Hey there - I'm a refrigeration salesman and I want to give you a heads up that in front of / behind the fan doesn't make a huge difference in most cases. Doing both front and back would double your efficiency though! Consider that box fans generally don't move air super efficiently. The air movement itself is kind of the weakest link here - get a centrifugal fan or one of those really strong metal shop fans. If it can't consistently blow papers off a table from 15 feet away, it needs improvement.
I would pick a better fan and run a two step system. I would put a copper coil on the back of the fan to start the cool down to keep the motor running cool. Then I would put another coil on the front to cool the air further. I am not too smart but do not flow rates affect thermal transfer? If so running the ice water at different rates should make cooling a room easy right? So a two stage system would be a better design?
With your 10lbs of ice how long does it last till its all water? I just wanted to know about how long till it all the ice meltdowns... Thanks
This doesnt work that well in a highly humid climate. I went through 20 lbs of ice in 4 hrs and caused so much condensation on the coil that I might as well have run a swamp cooler. It was a fun project/experiment though.
I think I'm gonna try something like this, but on a larger scale, using my ever flowing natural spring water, a forced air furnace blower, and some ductwork.
My spring water is usually right around 56 degrees year-round (probably warmer than the contents of your bucket, but will never warm up more than a couple degrees). It flows from the source, to my spring house, which is close to my actual house. So if I can somehow tap into the duct work of the house, I think I'd have a constant supply of approx 56 degree air entering my house for no more than the cost of running a blower motor.
Glad I found this video, thanks for posting it.
Hey bro did you try it? How did it work out??
Assuming a 70 degree room and 56 degree water, you're looking at a coil to air TD of 14 degrees. For reference, industrial refrigeration systems for meat packing plants target a 10-12 degree TD. I.E. if you pump enough water, your system is going to be pretty efficient.
Adjust the water flow upwards until the exit end of the coil is around 58 degrees and you're golden! No need to pump more than that - just adds heat from the motor / wastes energy.
Would 1/8 copper tubing work just fine? I'm finding it a lot cheaper.
Any estimates on the BCU of something like this using, say, 2 gallons of ice?
if you do two hole in refregertor you hav gate water from there .what you think its posible?
can u isolate the ice i mean insulate the holder so the ice is sealed and looses very little cool? could it last longer?
So I could put this in my garage in the summer and expect it to cool it down to 72 degrees? I live in Chicago. Usually temps are around 92 degrees tops.
Would this work better if instead of ice water we use freon?
where did you get the clear plastic tubing from?
wow good
Cool
Without the ice how much you think this would cool down the water. ? I am looking for a way to cool the water on my 40W Chinese laser.
I have a furnace with fan capability (furnace not burning). What if I put the coil in front of the intake grate? Will that make the air from the fan a little bit cooler?
do you have links to every item that was purchased?
How is the ice water circulating through?
Nice idea and implementation. I have a suggestion that might improve the efficiency. Instead of placing the ice and water in a normal bucket, it would be better if you put it in a styrofoam box with a lid so it stays colder for much longer. 🤔
Chipeat way use 20 ltr bucket put a 10 ltr bucket in center and fill the empty space between both with spry foam .. it will insulate the from outer temp 😀😀😀😀.
By insulating the bucket you actually reduce efficiency slightly, assuming the bucket is located in the room you are trying to cool. Think about it - the whole system is designed to absorb room heat and melt the ice as fast as possible, because that means its working.
Dump idea 😀
You could also put a PVC within a PVC. Pykrete on the out side with a pvc and copper coil with antifreeze on the inside sealed of course. Make a few to stick in a deep freezer connect them and run your system.
I wonder if Dry Ice would be better, I know you'd have to buy it, and it can cause burns, but it would be colder and last longer. I really like this video and I'm going to make it.
Got a couple of questions before I attempt to do this. I have a 20x20 (400sqft) dedicated workshop that currently has a 220v AC system designed for a 1,000sqft room. Its over kill, loud, sucks up too much power...and I need the one 220v socket it currently is using for my table saw. Sooo, I am looking to do something like this, or similar, for my own custom AC for the work shop.
1. Will this work well with a smaller "vornado" tilt fan - it has much more directed airflow but not being as big doesn't get the same air volume (I think)?
2. How long will a block (or say 10lb bag of ice) last before it completely melts and then is just circulating warm/hot water?
3. I have a small dorm fridge - I am thinking put putting a bucket of water in the fridge (it runs very low power) so its always keeping the water cold...and piping the tubing through the fridge into the reserve bucket. Fan/Fridge electricity should be minimal, but perpetual cool air should be available because the fridge will always be cooling the water - well, thats the thought at least. Thoughts on this technique? Fridge: www.compactappliance.com/Danby-Energy-Star-1-6-Cu-Ft-Compact-Refrigerator-Freezer/DCR016C1BDB.html
or what if you paint it flat black? Would the cooling be minimized because of the paint or will it improve?
Would windshield wiper fluid keep cold longer than water?
my not pumping right the clear tube keeps coming out from the fountain pump any suggestions
I like that idea. Thanks I may make me one it has to cut down on the electronic bill?
Adam Huff It really oly good for spot cooling your room or a hot kitchen . It will save and help you.
Would it matter if you put the copper coils on the back of the fan? I found your video a few days ago and I've put it all together. I haven't tried it out yet, and since I put the coil on the back, I wanted to know.
Try a Stirling cryogenic cooler to produce liquid air to circulate through that copper coil with a vapor tank to reform the liquid air has it boils off from the heat exchange. Could design the cooler motor to operate a pump to circulate the liquid air through the system hay a portable air conditioning unit?
Use a stinger in a insulated bucket of water and a fan with a metal housing and a hot water pump to heat a room?
