Hey fellas, thought I reach out with a quick question.... I LOVE this idea, and am currently waiting for my parts to arrive, but, as I understand it, the fan is DC powered? Since I am very much an electrical novice, how can I wire that to an AC outlet, since I won't have a solar panel? Any help would be greatly appreciated.
Nicely done man.... I already use that concept. flowing cold water thru used split A/C indoor unit and that concept is definitelly work. cooling down 6 sq meters room almost 2 degrees from 30c with just 1 liter of water and approx 1 kg ice, fully melted about 40 minutes in a really hot sunny day.
This is by far the most effective chilled water cooling system I have come across UA-cam in a very long time! Would it be possible to submerge copper coils into an ice-chest full of water, then later freezing the water during the night so you end up with an ice in the daytime, and pumping water through the coils submerged in the ice earlier to absorb heat from the fan-coil unit? A lot of building service engineers I have spoken with, and even Enwave in Chicago have used ice storage to cool buildings during the daytime since running chillers during off-peak hours is comparatively less expensive.
hi there and thanks. yeah this unit works great. i like your idea. may even make a video on it. it's very true that many buildings still use ice storage to cool buildings in the daytime. they freeze giant vats at night and then blow fans across it during the day for cheaper cooling. they usually use this in conjunction with regular ac but i've heard it can cut their electric bills by 35%. there's one company that has units in 4000 different companies. i saw one being used in a highrise in manhattan.
SWEET, have you tried it with a brine? salt water brine to circulate and salt ice to chill it, salt water gets colder and salt water ice takes longer to freeze but also to melt
To heat, Run glycol through some black pet or copper tubing coiled in a flat box outside,framed with 2x4’s & glass top, paint black inside. Heated by the sun, then just pump that thru the radiator instead of thru the ice chest. Use a couple valves and tees to switch over.
I'm guessing if one has some old A/C window units lying around, you could also use the heat exchangers off of them and save $44. Also, you could use those little portable ice makers to make the ice, to keep the water cool, if you are in an RV or something. I would think it would be more energy efficient, but I haven't run the numbers. There would be a lot of variables to consider.
Another idea from your video is to use your peltier ice chest fridge to keep water cooled to run through your heat exchanger. Maybe the thermal transfer from circulating over and over would exceed capacity of peltier ice chest fridge to keep up with heat exchanger. I'm just guessing I'm not an engineer. Maybe use a closed lid on ice chest and keep water in separated container within icechest to keep ice from melting so quickly.
Looks like the best I’ve seen yet. I want to build one for my SUV car camper. Can you use smaller heat exchanger with smaller hose lines or would that takeaway from efficiency? Could that unit be mounted on cooler cover? Thanks
hi and thanks! this one is a pretty powerful unit - but i do have other videos using smaller radiators and fans. those work great too! you can find them on my channel page (or by checking my 'air cooler' playlists) under the playlist tab. they are all grouped together on the playlists.
Now lets say you want to cool off water. Is it possible to submerge the Radiator in the tank and have it cycle the water through or is the fan needed to achieve the cooling results you have gotten?
hi. yes, it works very well in that range too. i've had several people tell me that they made them for use on boats. it's a great use and a good way to get cold water without ice
Valuable work. A crazy idea i want to try in Florida... I have a remote property in Central Florida. For Florida temperature not too bad at night for sleeping. Most charts say average Low in August is around 71F (but i think that is 5am). Most August nights i've tested at 11pm it's around 74F. Not terrible, but not ideal. I recently dug shallow well about 8' deep and the water down there is very cold.. I think under 68F. The space I need to cool is tiny , less than 50sqf with a metal skin. I am wondering I can pull or push air from the well/ground using a 8' x 6" pipe using a 5v 1amp USB fan to see a 3F temp decrease. Possibly pull cold water out into a copper coil or radiator and blow through it. Keep in mind this is at night but Florida is very humid. The ground where I would be pulling water and/or was covered by my van all day. Also wondering if pumping and spraying cold water on top of a metal structure would get me the 3F temp decrease?
Great video! I have just one question? Is the fan blowing through the heat exchange towards the wall, or sucking towards where you are sitting? Great design it has given me some ideas. Thanks for the share.
Could your power source be a ryobi 18v battery with a power wheel adapter? I like the solar power but makes it difficult if you want to bring it inside the house. Nice build by the way I am going to make an attempt at building it. Looking for a low cost way to cool a room when we have no power from hurricanes.
Sounds great! make sure to check my latest unit too. just posted it last Saturday. (on 08/26/2023). i've had many people make several of my projects with an 18V ryobi fan.
I've tried thsio but am now trying a smaller computer fan sized radiator as heat exchanger. Any thoughts on putting the radiator behind the fan? If I enclose the radiator on an insulated duct that draws cooler air from lower down I can keep it cooler than it would be if exposed to the warm air up higher.
Hi, that looks like a great set up. Do you think that heat exchanger will function if it is mounted upside down with the inlet and outlet facing down towards the cooler?
Very nice!! I want to build something similar to yours, but I want to have a battery bank to use it at night as well and the water would be cooled with a Peltier thermoelectric. Nice to see your system working of a solar panel. My question is...how large a solar panel would I need with batteries to work continously with 1 12v fan/ 1 12v water pump/ 4 36W peltier thermoelectric. I live in Aruba. Sun shines bright everyday for atleast 11 hours. Thank you for sharing this video.
I’m building something similar and was wondering where you get the pump to connection from? I have the water pump and the biggest connector is .75 which is a bit small for the hose line.
hi. i get the connectors from several places. marine stores are one good place. also amazon and the home stores (like home depot and lowes) are good places.
@@777steelerfan Not if it is kept in a closed container. IE a closed container of frozen salt water put into the air conditioners bath of water. From my own experience with my drink/food cooler, I have found out that the salt ice takes in more of the cold temp from the freezer, and therefore has a colder temperature then that of regular ice.
Nifty! You're really stepping things up. Now if you can add a water pump feeding a counter-top ice maker (both solar powered of course) from the melt in your ice chest which then feeds the ice chest with fresh ice cubes. :D :D :D
Wouldn't this setup work better if the heat exchanger was enclosed in the cooler? I noticed you didn't have much room in the cooler so that might explain it. As far as effectiveness for an enclosed cooler with a fan faced down on top sucking in hot air, I was told that was bad. Instead a setup like your vapor pad where you have the fan underneath some plywood and blowing cool air out a huge vent seems better. Just wasn't sure if having the exchanger underneath the fan sucking cold air out would be better than having the fan under the exchanger blowing out? Any thoughts?
Hi there! First, I want to say how much I enjoy your videos, I think they are fantastic! You inspired me to create my DIY cooler for my apartment here in Portland lol. I did have one question though. What type of water pumps do you use in your systems? I bought one from Amazon and the first few times I ran the cooler it worked great. I am noticing though that the pump seems to be getting pretty warm now to the point that it is heating up the water from the outlet hose 😒. I was hoping you might have some suggestions on good pumps or maybe if mine is too small and that's why it's heating up?
hi. i typically just buy any brand off of amazon when it comes to the pumps. they sell water pumps that you can use outside of the water if you want to. you just drop in the 2 hoses and the pump stays out of the water. i just bought one recently. they cost about 20 dollars so not much more than the other type.
Will increasing the size of heat exchanger say 19×20 for a 20"box fan produce better results or does it make the water warm quicker? Planning for my apt. Thanks.
Hi man i did a similar project but I didn't use a cooler but a freezer a made couple of holes and put an hermetic contenitor with a water pump. But I have a problem when is running the water is not cold at all like room temperature even with temp of -15. Any help or advice?(the room temp is around 28)
very nice..its a bit loud to my liking.... think you can increase the radiator size and reduce the fan speed to achieve same cooling and cut down on sound.... ? also when are you going to make this thing run of the swamp cooler you built.... ? that should be interesting...
hi there. the sound will vary depending on exact model of fan you use... but i've noticed that if i run it at 80% speed or less it's no louder than box fan on high. you can also decrease volume by adding a short section of pipe to the front of it. that acts like a muffler. your idea of a bigger fan at a slower speed would work too. i'm definitely going to be connecting this unit to the evap cube cooler for indirect evap cooling unit. just haven't gotten to it yet🙂
@@desertsun02 I've been using the water cooler you designed since I watched your video on it. It keeps my old fiver's bedroom cool at night here in the New Mexico summers. I"m absolutely gonna build this!
it varies quite a bit depending on how cold your water is (but it should cool 200 to 400 sq. ft.). the manufacturer states that can produce over 25,000 btu (if used as a heater) - but i'm not sure about the btu rating for cooling.
This may work better than the evaporative cooler one, I don't know. It might keep cool/cooler longer if the container were enclosed and insulated, I don't know. Thanks
Have you considered using a evap cooler running outside and piping the chill water from the tank into your heat exchanger? The temps probably wouldn't be nearly as cold. i think your chill water would only be down in the low 60s. But the whole setup would only require solar power and no ice.
hi. yes, absolutely. i've been thinking about that for awhile. i'll probably drop the piping into the reservoir of my "blue cube" evap. air cooler project. btw, your comment is exactly correct on every point 👍🙂
hi there. maybe make it all as one unit. meaning put the lid on the ice chest and attach the fan/radiator assembly to the lid. then cut 2 holes in the lid for the pipe. place unit somewhere in van and your're set. might make it too cold running on high but just use the speed control unit shown.
i may actually try that (connecting the two) and put it in the back seat of my car. cars interiors are like little solar ovens in the summer but i bet it would work just as good as the cars' actual ac unit...at least for a few hours at a time... and it should run off the cars cig. lighter
left me know if you do it. I've got solar and power banks I can run it off of. I've saved this to my favorite things list so I can refer back when I'm ready to compile materials.
Ann, I built this 2 weeks ago. I'm volunteering in Placitas NM where it's in the low 90's during the day and drops a few degrees each hour at night. Have used it both with ice and with just 55degree well water. I'm using an igloo cooler and the tops of igloos are not insulated so ice melts fast! Once I sprayed that Right Stuff inside the lid, I got 3x or 4x longer with ice before melting. It works and I'm happy with it so far in a chevy express van. By early in the morning the ice has melted and its just blowing cooler air using the water in the cooler that is still cooler than the air in the van. I've put the fan/radiator/controller piece together so it disconnects easily so it can fit inside the cooler when not in use. If you make it, keep that in mind - you know storage is at a premium. The fan is noisy but I've found that running it overnight at lower rpms works for me although blasting it feels great. I find the cfm overkill in the van. By the way, it's not an a/c. I certainly am comfortable even just using cold well water as a source but it ain't a/c. Runs of my 2 100ah lithium bats all night easily. Oh, when i get time i will try using it along with his solar hot water heater to see if it will heat the van - during the day at least. Would love to rely less on my Mr. Buddy propane heater - although it won't help at night or bad weather. But a dual use shower/heater has potential even if its only when the sun shines.
hi there. since there are dozens of companies selling all types of solar panels these days i tend not to post links for them. amazon has pages and pages of different kinds and brands. i used to go with the name brand ones but i'm finding that even the cheapest ones work just as good or even better than the expensive ones. here is a link to a 12v 100w one that is only about 80 dollars www.amazon.com/HQST-Efficiency-Battery-Charging-Applications/dp/B08SWJK87H/ref=sr_1_12?crid=3QDV6W56PF5NM&keywords=100+w+poly+solar+panels&qid=1657473561&sprefix=100+w+poly+solar+panels%2Caps%2C259&sr=8-12
hi there. no that's not an issue where i live. never hits the dew point. if it does happen just wrap a towel around the top. the bottom part is open so you could set it on a towel or you could just put a small drip tray underneath it (maybe just made out of tin foil)

hi there. sounds like you got a great plan. if your running it on DC Power i'd use a 350 gph 12v bilge pump. 18x18 is a really good size unit. might even be able to use a 500 gpher. if using AC power i'd use a 400 gph water pump. probably an aquarium water pump. good luck to you. sounds like you're going to have a great system.
It's a copper heat exchanger that is manufactured in a facility. Amazon search "copper heat exchanger or copper heater core", many options and price ranges will appear. Definitely a great looking way to go about a DIY air cooler.
hi there. it's super cheap to run. it costs about $5 a month to run the entire set up using AC power. (and that includes the making all the ice in your own kitchen fridge!). so, total (over a 30 day month) about 5 bucks extra in electricity. i've got a more detailed breakdown of the costs in a 2nd video of this set up. - if interested, here's the link to that one. (the cost breakdown is in the last couple minutes ua-cam.com/video/dLspmypEqhM/v-deo.html
@@hebertsbonilla7405 I saw this other guy on yt, use solar with 1000w converter, run efficient freezer/fridge that uses around 450watt if i remember correctly, it only takes few hours to make ice, probably best to keep freezer outside the house else you will be heating the room, you can stock up on that way too. that heat exchange you got there looks very beefy, alternative is to use motocycle they probably cheaper too.
Hi Im looking to build something similar but I'll be using a 200-500 cfm fan (for a small bedroom 1224 cubic feet). Do you think a 160 gph pump would be decent?
hi there. i've been meaning to experiment with hot water, but haven't yet. i'd guess a few hours at a time. i'll be making a heater vid. on this soon 🙂
i have it set up to pull the air thru the heat exchanger and blow it out into the room. *i've found that doing it that way gives a much better air flow than trying to push the air thru the unit.
I'm struggling with the water warming up too fast. I've tried using ice water in the cooler, ice melts fast, water warms up. I'v tried using a gallon of water with the pump around the gallon, but the ice doesn't really cool the gallon at all.. Metal container of water is my next step... Any suggestions? I'm freezing water bottles and a couple of juices bottles (half gallon) and Ice from the gas station.... I feel like a ton of work is going into the cooling of the water... The system works great though if the water is cold... Im using this just to cool my Garage.... Arizona garage!
hi there. since you are in arizona you might consider chilling the water with a homemade evap cooler. i've got a video on how to make one (the blue cube evap cooler one). those chill the water in the water reservoir when it's running. i've seen the water in those go from 85F down to as low as 57F in just minutes. you could put the pipes from the heat exchanger into the that. (that's something i've been meaning to try for awhile). it might balance out well. (one cooling the water and the other heating it up). if you don't want to do that (and you don't have cold 'well water' or a cool lake or river water source) then the best way to keep the water cold that i know of is to use large ice blocks. one other thing... make sure the pump isn't oversized. it may be heating up the water that it's in. maybe you could use a pump that you don't need to put in the water. hope that helps and it's great you made it! as you mentioned, they do work great (just need the cold water)
@@desertsun02 Well you just hit on something... I think you used a 350gph pump. I was using a smaller pump, but my water supply was in a cooler on the ground, while my fan/heat exchanger was on my work table. The pump I had wasn't strong enough to push the water UP through the hose (which are also too long) , so it was either place the water closer to the fan or upgrade the pump.... I went with an 1100gph pump! Lmao yeah, so maybe the pump IS heating up the water! Didn't even think about that as a possibility. I used a cooler with ice and frozen water bottles & frozen juice bottles and it melted fast. Worked great for a bit though before the temp rose... Damn pump. I'll swap it out and see how it goes. I'm using a 100w solar setup similar to the one in your video. Thanks for the education on that too, been subscribed for years. Excellent videos. My family thinks I'm nuts, but I'm having fun. Built the evap box fan cooler several years ago from your vids, thank you.. I'll report back and see how the pump swap goes.
hi. where i live the humidity is pretty low so i don't have any condensation. you could use a drip tray or even just a towel to catch any if it's an issue where you are.
hey thanks. yep, as far as sheer power goes it really cranks out the cold air. you can get that type of hose at most home stores (i think i got it at home depot). also a lot of marine supply stores have a lot of large diameter vinyl hose. they often sell it by the foot too. they are one inch internal diameter. tip: look around for best price. i've seen it anywhere from $5 to $20
I just commented on your video where you pump heat from the water heater. I want to make something like this but in a way that pumps liquid cooled from being underground. I see a potential problem in the pumps since they need to pump probably around a ton of water if it does go down that deep to where it can cool using the ground. So there might be an issue in scaling. What do you think? I hope you get a chance to reply. Thanks.
hi there. well, i've never done a geo-thermal one but i like the idea for sure. it's a bit of work up front but then you've got a great source of cool water. if you're well water is 55F as an example then you are set!
@@desertsun02 Thanks for replying. It looks like buring 10 feet deep for a horizontal loop is good enough for cooling. You wouldn't need to touch groundwater. That's what got me thinking of getting a stronger pump since it's more than 20 feet just from the side of the house to the bottom of the trench. Everything else just adds more to it, like going ten feet out on a loop system could get you 100 feet total for a small system. So I imagine you need stronger pumps that depend on the amount of liquid that depends on the length of overall hose.
hey there. here are 2 links. this one is the link to all 3 pages of them badger-pipe.com/collections/water-to-air-heat-exchanger this one is the link to the 8x8 heat exchanger (it's the exact one i used) badger-pipe.com/collections/water-to-air-heat-exchanger/products/8x8-water-to-air-heat-exchanger-1-copper-ports?variant=29080937105
hi. depends on how fast you run it. at full speed it is (but at half speed or three quarter speed it's no louder than a box fan). if noise is a little loud their are easy ways to muffle the sound.
hi. amazon is the best place. the heat exchanger is from a company called 'badger insulated pipe'. you can get it on their website and on amazon. they are still setting the heat exchanger radiator for about 42 dollars. the fan and water pump can be found on amazon. they have many. let me see if i can get you a link to the radiator. looks like it went up to $71.00. inflation. here is the link. tinyurl.com/hbkswvw7 they may have cheaper ones on amazon. i just checked and they do have cheaper ones. here is a link to a $49.00 one of the same size. tinyurl.com/3cnk3rbt and here is a link to a $63.00 one tinyurl.com/ycy54dvw
@@desertsun02 did you ever consider building one that had another exchanger in the cooler and fill the exchangers and hoses with coolant etc something that wont freeze and filling the cooler with dry ice and water ...or just packed full with ice idk lol just a thought. I think im going to build somthing incoporated into the deck extension on my bass boat .. ive bought a under dash fan evap combo for adding ac to tractor etc from amazon vents tubing etc .. hope it works out
I've had this idea for years but never made one. I have a problem with what I'm seeing though. Looking at the clear hose going into and out of the radiator, one hose is full of water and the other is empty. Both hoses being vertical like that would have to be full of water if the water was going thru the radiator.
hi. good question. each pipe has an equal amount of water flowing thru it. neither pipe is even close to full, maybe 1/4 full, but that's normal. it looks that way on one side because the water bottle necks . but the unit itself is actually full all the time.
hi the links for the heat exchangers change all the time. i don't know why. best to just search for 8 by 8 heat exchanger and you'll see them. there are at least 3 companies on amazon that sell them. i'll take a look at the link, and post a new link. Update: i just posted the new link! it's in description section below or just click here www.amazon.com/Water-Exchanger-1-Copper-Install-Flange/dp/B07VPBSFQC/ref=sr_1_3?keywords=8x8+heat+exchanger&qid=1576173824&sr=8-3
Have you tried adding a duct? I was wondering how this kind of fan and duct would work connected to it. Global Industrial™ Flame Retardant Flexible Duct 16Ft for 8 Inch Diameter Fan. Do you think it would work well?
hi there. i have tried it with flexible ducting. only a 3 foot section though (not a full 16 feet). works very well. one side benefit of the ducting (that i wasn't expecting) is that it muffles the sound of the fan motor almost completely. with the ducting connected, all you mainly hear is the sound of the air rushing out of the tube.
@@desertsun02 Do you think installing one of those fans at each end of the ducting would be beneficial? One fan connected to the heat exchanger, the other at the other end of the 16 ft of ducting to help suck the air out of the ducting.
hi. it varies a lot depending on how fast you run the fan. (plus other factors like how hot the room is to start with, how much ice you use or if it's just cool water...)
I love these ice chest spot cooler videos...I had no idea how many "experts" in Thermodynamics also troll UA-camrs when they're not doing dynamic work with hot and cold stuff...
An answer from an observer...It all depends on the fan and how much CFM volume it can push with the available cold water running through the system..Both are limited... to the amount of ice available and the amount of cubic feet of air the fan can push.. The previous video I saw he showed a 20 degree drop between ambient/cooled air... but this was also at the lower areas of the room which has cooler air too (hot air rises)..My guess is its limited to the CFM.. but I suppose if he put the "concept" high in the room and had a way to constantly feed the water bin with ice jugs to replenish the cold it could gradually bring the "whole" house temperature down...
@@kevinrehberg8758 Should do the trick for my stealth campervan and my woods camp. I can make all the free ice I want at my warehouse (free electric) which is a quick 1/4 mile from my warehouse. Florida summers are brutal and I know condensation coolers are useless here. Cheers
hi. i hear that concept from time to time so here's my take on that...i get your point, but that only applies theoretically in the specific circumstance that the cooling unit and your freezer are in the same space your trying to cool, it's an enclosed space, they're both running simultaneously and the heat and cold are being dispersed equally. in most real world cases (like freezing the ice at night and using the unit during day) or at any different times then when you're running it negates that. also if freezer is in a different room, downstairs, outside etc... changes the equation. an example...say my bedroom is hot. what do i care if the kitchen is 1 degree warmer when it's freezing the ice in the afternoon or anytime really. the heat that the fridge produces will just rise to the ceiling and up thru the attic and out. my point is there is almost no scenario where this won't cool an area of your house. but again i do get your point. if the cooler is meant to cool your entire house (including the kitchen) at the same time the ice is being frozen they can cancel each other out. hopefully that long-winded answer will be of help to anyone who reads it :)
@@desertsun02I have just spent about 2 hours watching all of your videos. I am going to build 2 of these units Tuesday. I applaud your talent and I too am a off grid sort of person (see my vids). I have access to a river down here on my property in Crystal River, Florida. While the average temps are 95 degrees, the river temp is always about 55 degrees. I was wondering about looping into it to eliminate the ice chest all together... just didn't know how well 55 degree would allow for cold output from the exchanger. Another thought I had was looping into the outdoor cool air blower unit you have constructed. That water also runs about 55 degrees but would literally be very close to pipe into and would also eliminate the ice chest requirement. It could also provide a water reservoir source for multiple blower units to cool more than 1 room at a time. Please let me know your thoughts. Keep up the excellent work.
I built one for a garage area...works great....motor controller makes it nice to control speed of the fan....Great idea!
hi there. that's awesome! i've been using mine everyday. already saved like 50 bucks in electricity since i don't need the AC now.
Hey fellas, thought I reach out with a quick question.... I LOVE this idea, and am currently waiting for my parts to arrive, but, as I understand it, the fan is DC powered? Since I am very much an electrical novice, how can I wire that to an AC outlet, since I won't have a solar panel? Any help would be greatly appreciated.
Awesome build!!!
Just a thought from an old bartender...
A beer keg "Jockey Box" would keep the water consistently cold until all the ice melts.
good idea! 👍
Nicely done man.... I already use that concept. flowing cold water thru used split A/C indoor unit and that concept is definitelly work. cooling down 6 sq meters room almost 2 degrees from 30c with just 1 liter of water and approx 1 kg ice, fully melted about 40 minutes in a really hot sunny day.
This is by far the most effective chilled water cooling system I have come across UA-cam in a very long time!
Would it be possible to submerge copper coils into an ice-chest full of water, then later freezing the water during the night so you end up with an ice in the daytime, and pumping water through the coils submerged in the ice earlier to absorb heat from the fan-coil unit? A lot of building service engineers I have spoken with, and even Enwave in Chicago have used ice storage to cool buildings during the daytime since running chillers during off-peak hours is comparatively less expensive.
hi there and thanks. yeah this unit works great. i like your idea. may even make a video on it. it's very true that many buildings still use ice storage to cool buildings in the daytime. they freeze giant vats at night and then blow fans across it during the day for cheaper cooling. they usually use this in conjunction with regular ac but i've heard it can cut their electric bills by 35%. there's one company that has units in 4000 different companies. i saw one being used in a highrise in manhattan.
best DIY design ive seen, subscribed... added to my favorite
SWEET, have you tried it with a brine? salt water brine to circulate and salt ice to chill it, salt water gets colder and salt water ice takes longer to freeze but also to melt
mix in coolant lol
DIY A/C that cost less than a A/C! I like it.
For heat you can drop in a aquarium heater they usually adjust up to 85 degrees Fahrenheit
To heat, Run glycol through some black pet or copper tubing coiled in a flat box outside,framed with 2x4’s & glass top, paint black inside. Heated by the sun, then just pump that thru the radiator instead of thru the ice chest. Use a couple valves and tees to switch over.
thank a lot for your internet video it assists a whole lot.
Genius!😮😊Nerds for the win!
I'm guessing if one has some old A/C window units lying around, you could also use the heat exchangers off of them and save $44. Also, you could use those little portable ice makers to make the ice, to keep the water cool, if you are in an RV or something. I would think it would be more energy efficient, but I haven't run the numbers. There would be a lot of variables to consider.
Suggest to lag the pipes and insulate the copper part of HE exposed👍
Nice one.. excellent.. Thanks..

hi there, glad you enjoyed it! 🙂
U just give me a great idea, car radiator all 12v with fan, thanks !!! 🍺🍺🍺
Another idea from your video is to use your peltier ice chest fridge to keep water cooled to run through your heat exchanger. Maybe the thermal transfer from circulating over and over would exceed capacity of peltier ice chest fridge to keep up with heat exchanger.
I'm just guessing I'm not an engineer.
Maybe use a closed lid on ice chest and keep water in separated container within icechest to keep ice from melting so quickly.
Looks like the best I’ve seen yet. I want to build one for my SUV car camper. Can you use smaller heat exchanger with smaller hose lines or would that takeaway from efficiency? Could that unit be mounted on cooler cover? Thanks
hi and thanks! this one is a pretty powerful unit - but i do have other videos using smaller radiators and fans. those work great too! you can find them on my channel page (or by checking my 'air cooler' playlists) under the playlist tab. they are all grouped together on the playlists.
Now lets say you want to cool off water. Is it possible to submerge the Radiator in the tank and have it cycle the water through or is the fan needed to achieve the cooling results you have gotten?
The build costs as much as a window A/C, but uses less power. Nice build.
Looking at adding this type to my boat. Water temp is usually under 62 all summer have you tested water in that temp range to see how it does.
hi. yes, it works very well in that range too. i've had several people tell me that they made them for use on boats. it's a great use and a good way to get cold water without ice
Valuable work. A crazy idea i want to try in Florida... I have a remote property in Central Florida. For Florida temperature not too bad at night for sleeping. Most charts say average Low in August is around 71F (but i think that is 5am). Most August nights i've tested at 11pm it's around 74F. Not terrible, but not ideal. I recently dug shallow well about 8' deep and the water down there is very cold.. I think under 68F. The space I need to cool is tiny , less than 50sqf with a metal skin. I am wondering I can pull or push air from the well/ground using a 8' x 6" pipe using a 5v 1amp USB fan to see a 3F temp decrease. Possibly pull cold water out into a copper coil or radiator and blow through it. Keep in mind this is at night but Florida is very humid. The ground where I would be pulling water and/or was covered by my van all day. Also wondering if pumping and spraying cold water on top of a metal structure would get me the 3F temp decrease?
Great video! I have just one question? Is the fan blowing through the heat exchange towards the wall, or sucking towards where you are sitting?
Great design it has given me some ideas. Thanks for the share.
hi and thanks! it's blowing out towards where i am sitting.
@@desertsun02 where do you get your condensers from?
Could your power source be a ryobi 18v battery with a power wheel adapter? I like the solar power but makes it difficult if you want to bring it inside the house. Nice build by the way I am going to make an attempt at building it. Looking for a low cost way to cool a room when we have no power from hurricanes.
Sounds great! make sure to check my latest unit too. just posted it last Saturday. (on 08/26/2023). i've had many people make several of my projects with an 18V ryobi fan.
I've tried thsio but am now trying a smaller computer fan sized radiator as heat exchanger. Any thoughts on putting the radiator behind the fan? If I enclose the radiator on an insulated duct that draws cooler air from lower down I can keep it cooler than it would be if exposed to the warm air up higher.
Hi, that looks like a great set up. Do you think that heat exchanger will function if it is mounted upside down with the inlet and outlet facing down towards the cooler?
hi. yes, i think it would
Very nice!! I want to build something similar to yours, but I want to have a battery bank to use it at night as well and the water would be cooled with a Peltier thermoelectric. Nice to see your system working of a solar panel. My question is...how large a solar panel would I need with batteries to work continously with 1 12v fan/ 1 12v water pump/ 4 36W peltier thermoelectric. I live in Aruba. Sun shines bright everyday for atleast 11 hours.
Thank you for sharing this video.
I’m building something similar and was wondering where you get the pump to connection from? I have the water pump and the biggest connector is .75 which is a bit small for the hose line.
hi. i get the connectors from several places. marine stores are one good place. also amazon and the home stores (like home depot and lowes) are good places.
@@desertsun02 thanks. I was able to get them from Menards.
@Seven Chang awesome!
Awesome stuff! BTW, adding a half cup or so of salt to each of your gallon jugs of water and then freezing it, will yield much colder ice!
good tip!
Wouldn’t the salt going through the heat exchanger rust out the metal?
@@777steelerfan Not if it is kept in a closed container. IE a closed container of frozen salt water put into the air conditioners bath of water. From my own experience with my drink/food cooler, I have found out that the salt ice takes in more of the cold temp from the freezer, and therefore has a colder temperature then that of regular ice.
Nifty! You're really stepping things up. Now if you can add a water pump feeding a counter-top ice maker (both solar powered of course) from the melt in your ice chest which then feeds the ice chest with fresh ice cubes. :D :D :D
I thought of that for an off-grid treehouse. I don't think they use that much power either. You could have it dump right in the cooler. Cheers
Wouldn't this setup work better if the heat exchanger was enclosed in the cooler? I noticed you didn't have much room in the cooler so that might explain it. As far as effectiveness for an enclosed cooler with a fan faced down on top sucking in hot air, I was told that was bad. Instead a setup like your vapor pad where you have the fan underneath some plywood and blowing cool air out a huge vent seems better. Just wasn't sure if having the exchanger underneath the fan sucking cold air out would be better than having the fan under the exchanger blowing out? Any thoughts?
Would you be able to recycle a heat exchanger from an old refrigerator or any other ideas where to get a heat exchanger that could be recycled?
I made a smaller version of this for our fire truck. How are you combatting the condensation coming off the exchanger
hi there. where i live it's so dry that that isn't an issue.
Very cool 😎
thank you 🙂
Hi there! First, I want to say how much I enjoy your videos, I think they are fantastic! You inspired me to create my DIY cooler for my apartment here in Portland lol. I did have one question though. What type of water pumps do you use in your systems? I bought one from Amazon and the first few times I ran the cooler it worked great. I am noticing though that the pump seems to be getting pretty warm now to the point that it is heating up the water from the outlet hose 😒. I was hoping you might have some suggestions on good pumps or maybe if mine is too small and that's why it's heating up?
hi. i typically just buy any brand off of amazon when it comes to the pumps. they sell water pumps that you can use outside of the water if you want to. you just drop in the 2 hoses and the pump stays out of the water. i just bought one recently. they cost about 20 dollars so not much more than the other type.
Will increasing the size of heat exchanger say 19×20 for a 20"box fan produce better results or does it make the water warm quicker? Planning for my apt. Thanks.
You come up with some great ideas, thank you so much for all.
Hi man i did a similar project but I didn't use a cooler but a freezer a made couple of holes and put an hermetic contenitor with a water pump. But I have a problem when is running the water is not cold at all like room temperature even with temp of -15. Any help or advice?(the room temp is around 28)
very nice..its a bit loud to my liking.... think you can increase the radiator size and reduce the fan speed to achieve same cooling and cut down on sound.... ? also when are you going to make this thing run of the swamp cooler you built.... ? that should be interesting...
hi there. the sound will vary depending on exact model of fan you use... but i've noticed that if i run it at 80% speed or less it's no louder than box fan on high. you can also decrease volume by adding a short section of pipe to the front of it. that acts like a muffler. your idea of a bigger fan at a slower speed would work too. i'm definitely going to be connecting this unit to the evap cube cooler for indirect evap cooling unit. just haven't gotten to it yet🙂
That looks amazing!
hi there. thanks. it's definitely one of the best i;ve made. i hope you try it.
@@desertsun02 I've been using the water cooler you designed since I watched your video on it. It keeps my old fiver's bedroom cool at night here in the New Mexico summers. I"m absolutely gonna build this!
Any thoughts on what size room would be a fit for this design?
it varies quite a bit depending on how cold your water is (but it should cool 200 to 400 sq. ft.). the manufacturer states that can produce over 25,000 btu (if used as a heater) - but i'm not sure about the btu rating for cooling.
This may work better than the evaporative cooler one, I don't know. It might keep cool/cooler longer if the container were enclosed and insulated, I don't know. Thanks
What's the (minimum) Wattage of the Solar panel to run both Fan and Pump ? THX
hi. about a 12v 100 watt panel. you have to consider amps too. so for full power maybe 150w one
Have you considered using a evap cooler running outside and piping the chill water from the tank into your heat exchanger? The temps probably wouldn't be nearly as cold. i think your chill water would only be down in the low 60s. But the whole setup would only require solar power and no ice.
hi. yes, absolutely. i've been thinking about that for awhile. i'll probably drop the piping into the reservoir of my "blue cube" evap. air cooler project. btw, your comment is exactly correct on every point 👍🙂
@@desertsun02 cant wait to see it I've been pondering a setup using a car radiator vice the copper tube. Or maybe a combination of both.
Even if you don't put ice into the system you'll get fresh air
Yes it would be better than a fan only setting on a regular ac.
this is so cool. wish there was a way to implement this in my van.
hi there. maybe make it all as one unit. meaning put the lid on the ice chest and attach the fan/radiator assembly to the lid. then cut 2 holes in the lid for the pipe. place unit somewhere in van and your're set. might make it too cold running on high but just use the speed control unit shown.
hmmm you got me thinking...
i may actually try that (connecting the two) and put it in the back seat of my car. cars interiors are like little solar ovens in the summer but i bet it would work just as good as the cars' actual ac unit...at least for a few hours at a time... and it should run off the cars cig. lighter
left me know if you do it. I've got solar and power banks I can run it off of. I've saved this to my favorite things list so I can refer back when I'm ready to compile materials.
Ann, I built this 2 weeks ago. I'm volunteering in Placitas NM where it's in the low 90's during the day and drops a few degrees each hour at night. Have used it both with ice and with just 55degree well water. I'm using an igloo cooler and the tops of igloos are not insulated so ice melts fast! Once I sprayed that Right Stuff inside the lid, I got 3x or 4x longer with ice before melting. It works and I'm happy with it so far in a chevy express van. By early in the morning the ice has melted and its just blowing cooler air using the water in the cooler that is still cooler than the air in the van. I've put the fan/radiator/controller piece together so it disconnects easily so it can fit inside the cooler when not in use. If you make it, keep that in mind - you know storage is at a premium. The fan is noisy but I've found that running it overnight at lower rpms works for me although blasting it feels great. I find the cfm overkill in the van. By the way, it's not an a/c. I certainly am comfortable even just using cold well water as a source but it ain't a/c. Runs of my 2 100ah lithium bats all night easily.
Oh, when i get time i will try using it along with his solar hot water heater to see if it will heat the van - during the day at least. Would love to rely less on my Mr. Buddy propane heater - although it won't help at night or bad weather. But a dual use shower/heater has potential even if its only when the sun shines.
How come you don't have a link for the solar panel? Could you provide one please?
hi there. since there are dozens of companies selling all types of solar panels these days i tend not to post links for them. amazon has pages and pages of different kinds and brands. i used to go with the name brand ones but i'm finding that even the cheapest ones work just as good or even better than the expensive ones. here is a link to a 12v 100w one that is only about 80 dollars www.amazon.com/HQST-Efficiency-Battery-Charging-Applications/dp/B08SWJK87H/ref=sr_1_12?crid=3QDV6W56PF5NM&keywords=100+w+poly+solar+panels&qid=1657473561&sprefix=100+w+poly+solar+panels%2Caps%2C259&sr=8-12
Do you have any problems with condensation coming off the heat exchanger?
hi there. no that's not an issue where i live. never hits the dew point. if it does happen just wrap a towel around the top. the bottom part is open so you could set it on a towel or you could just put a small drip tray underneath it (maybe just made out of tin foil)

hi there. sounds like you got a great plan. if your running it on DC Power i'd use a 350 gph 12v bilge pump. 18x18 is a really good size unit. might even be able to use a 500 gpher. if using AC power i'd use a 400 gph water pump. probably an aquarium water pump. good luck to you. sounds like you're going to have a great system.
I like it.......I like it a lot !
how did you solder the pipe joints, the work is actually really beautifully done with the copper
It's a copper heat exchanger that is manufactured in a facility. Amazon search "copper heat exchanger or copper heater core", many options and price ranges will appear. Definitely a great looking way to go about a DIY air cooler.
this affects bills? even if i run it on socket?
hi there. it's super cheap to run. it costs about $5 a month to run the entire set up using AC power. (and that includes the making all the ice in your own kitchen fridge!). so, total (over a 30 day month) about 5 bucks extra in electricity. i've got a more detailed breakdown of the costs in a 2nd video of this set up. - if interested, here's the link to that one. (the cost breakdown is in the last couple minutes ua-cam.com/video/dLspmypEqhM/v-deo.html
Free Ice?
total Watt to produce ice from the fridge? Im assuming your fridge runs off the mains grid
I think that even if you don't put some ice into the system you'll get fresh air
@@hebertsbonilla7405 I saw this other guy on yt, use solar with 1000w converter, run efficient freezer/fridge that uses around 450watt if i remember correctly, it only takes few hours to make ice, probably best to keep freezer outside the house else you will be heating the room, you can stock up on that way too. that heat exchange you got there looks very beefy, alternative is to use motocycle they probably cheaper too.
How long before you have to add more ice?
i usually get several hours (but it will depend a lot on how fast you run the fan (and how hot the air is in the room))
Wonder how long the water would stay cold outside?
Hi Im looking to build something similar but I'll be using a 200-500 cfm fan (for a small bedroom 1224 cubic feet). Do you think a 160 gph pump would be decent?
hi. a 160 gph one might be a little too small. i'd go with a minimum of 200. *350'ers work great too (that may become my standard)
@@desertsun02 ok thanks!
how long do you think this would output heat if used as a heater with hot water in the cooker? would it last 8 hours?
thanks very much
hi there. i've been meaning to experiment with hot water, but haven't yet. i'd guess a few hours at a time. i'll be making a heater vid. on this soon 🙂
thank you very much i look forward to your video and results. much appreciated
Use a hotplate under an insulated metal bucket. Electric or gas or rocketstove.
WHAT KIND OF FAN IS THIS...I suppose it’s got to reverse the air off the heat exchanger? Thanx Sarge.
hi. its a 7" car radiator fan. 👍
Sorry to be so dense does this blow into the heat exchanger or pull air out????
i have it set up to pull the air thru the heat exchanger and blow it out into the room. *i've found that doing it that way gives a much better air flow than trying to push the air thru the unit.
I’m trying to cool down a 95 degree garage where to huge dogs live....fans blow hot air. Is this radiator fan blowing in or out??????
Ok thanx. To the auto parts store...
I'm struggling with the water warming up too fast. I've tried using ice water in the cooler, ice melts fast, water warms up. I'v tried using a gallon of water with the pump around the gallon, but the ice doesn't really cool the gallon at all.. Metal container of water is my next step... Any suggestions? I'm freezing water bottles and a couple of juices bottles (half gallon) and Ice from the gas station.... I feel like a ton of work is going into the cooling of the water... The system works great though if the water is cold... Im using this just to cool my Garage.... Arizona garage!
hi there. since you are in arizona you might consider chilling the water with a homemade evap cooler. i've got a video on how to make one (the blue cube evap cooler one). those chill the water in the water reservoir when it's running. i've seen the water in those go from 85F down to as low as 57F in just minutes. you could put the pipes from the heat exchanger into the that. (that's something i've been meaning to try for awhile). it might balance out well. (one cooling the water and the other heating it up). if you don't want to do that (and you don't have cold 'well water' or a cool lake or river water source) then the best way to keep the water cold that i know of is to use large ice blocks. one other thing... make sure the pump isn't oversized. it may be heating up the water that it's in. maybe you could use a pump that you don't need to put in the water. hope that helps and it's great you made it! as you mentioned, they do work great (just need the cold water)
@@desertsun02 Well you just hit on something... I think you used a 350gph pump. I was using a smaller pump, but my water supply was in a cooler on the ground, while my fan/heat exchanger was on my work table. The pump I had wasn't strong enough to push the water UP through the hose (which are also too long) , so it was either place the water closer to the fan or upgrade the pump.... I went with an 1100gph pump! Lmao yeah, so maybe the pump IS heating up the water! Didn't even think about that as a possibility. I used a cooler with ice and frozen water bottles & frozen juice bottles and it melted fast. Worked great for a bit though before the temp rose... Damn pump. I'll swap it out and see how it goes. I'm using a 100w solar setup similar to the one in your video. Thanks for the education on that too, been subscribed for years. Excellent videos. My family thinks I'm nuts, but I'm having fun. Built the evap box fan cooler several years ago from your vids, thank you.. I'll report back and see how the pump swap goes.
THANK YOU!
The coil doesn’t condensation water ?
hi. where i live the humidity is pretty low so i don't have any condensation. you could use a drip tray or even just a towel to catch any if it's an issue where you are.
This looks like your best AC build yet. Where did you get those plastic hoses, what size are they?
hey thanks. yep, as far as sheer power goes it really cranks out the cold air. you can get that type of hose at most home stores (i think i got it at home depot). also a lot of marine supply stores have a lot of large diameter vinyl hose. they often sell it by the foot too. they are one inch internal diameter. tip: look around for best price. i've seen it anywhere from $5 to $20
@@desertsun02 thanks 👍🏼
I just commented on your video where you pump heat from the water heater. I want to make something like this but in a way that pumps liquid cooled from being underground. I see a potential problem in the pumps since they need to pump probably around a ton of water if it does go down that deep to where it can cool using the ground. So there might be an issue in scaling. What do you think? I hope you get a chance to reply. Thanks.
hi there. well, i've never done a geo-thermal one but i like the idea for sure. it's a bit of work up front but then you've got a great source of cool water. if you're well water is 55F as an example then you are set!
@@desertsun02 Thanks for replying. It looks like buring 10 feet deep for a horizontal loop is good enough for cooling. You wouldn't need to touch groundwater. That's what got me thinking of getting a stronger pump since it's more than 20 feet just from the side of the house to the bottom of the trench. Everything else just adds more to it, like going ten feet out on a loop system could get you 100 feet total for a small system. So I imagine you need stronger pumps that depend on the amount of liquid that depends on the length of overall hose.
whats the coldest temp that you can get one meter away from the blower
awesome!
Can you add link to heat exchanger ? Can’t find it on Amazon.

Is the fan loader then window ac unit
hi. depends on how fast you run it. at full speed it is (but at half speed or three quarter speed it's no louder than a box fan). if noise is a little loud their are easy ways to muffle the sound.
wonder if two radiator are used, very cool
I have been wanting to do this setup, but my problem is that I cannot seem to source a copper tube and fin heat exchanger. Any tips on how to get one?
hi. they got lots of them on amazon. just search 8 x 8 water to air heat exchanger
desertsun02 Thank you!
where do you get the coil and other parts and how much is it
Amazon
hi. amazon is the best place. the heat exchanger is from a company called 'badger insulated pipe'. you can get it on their website and on amazon. they are still setting the heat exchanger radiator for about 42 dollars. the fan and water pump can be found on amazon. they have many. let me see if i can get you a link to the radiator. looks like it went up to $71.00. inflation. here is the link. tinyurl.com/hbkswvw7 they may have cheaper ones on amazon. i just checked and they do have cheaper ones. here is a link to a $49.00 one of the same size. tinyurl.com/3cnk3rbt and here is a link to a $63.00 one tinyurl.com/ycy54dvw
@@desertsun02 did you ever consider building one that had another exchanger in the cooler and fill the exchangers and hoses with coolant etc something that wont freeze and filling the cooler with dry ice and water ...or just packed full with ice idk lol just a thought. I think im going to build somthing incoporated into the deck extension on my bass boat .. ive bought a under dash fan evap combo for adding ac to tractor etc from amazon vents tubing etc .. hope it works out
I've had this idea for years but never made one. I have a problem with what I'm seeing though. Looking at the clear hose going into and out of the radiator, one hose is full of water and the other is empty. Both hoses being vertical like that would have to be full of water if the water was going thru the radiator.
hi. good question. each pipe has an equal amount of water flowing thru it. neither pipe is even close to full, maybe 1/4 full, but that's normal. it looks that way on one side because the water bottle necks . but the unit itself is actually full all the time.
Would any heat exchanger work. Ex, computer radiator
Because the link is no longer available
hi the links for the heat exchangers change all the time. i don't know why. best to just search for 8 by 8 heat exchanger and you'll see them. there are at least 3 companies on amazon that sell them. i'll take a look at the link, and post a new link.

What size pump did u use? Thx
hi. i've tried 2 different ones. a 200gph one and a 12v 350gph bilge pump. they both work well.
How did you attach the fan to the power source?
Have you tried adding a duct? I was wondering how this kind of fan and duct would work connected to it. Global Industrial™ Flame Retardant Flexible Duct 16Ft for 8 Inch Diameter Fan. Do you think it would work well?
hi there. i have tried it with flexible ducting. only a 3 foot section though (not a full 16 feet). works very well. one side benefit of the ducting (that i wasn't expecting) is that it muffles the sound of the fan motor almost completely. with the ducting connected, all you mainly hear is the sound of the air rushing out of the tube.
@@desertsun02 Do you think installing one of those fans at each end of the ducting would be beneficial? One fan connected to the heat exchanger, the other at the other end of the 16 ft of ducting to help suck the air out of the ducting.
Add some rock salt and see what it will do , it should last longer the Ice will stay around longer
But how much humidity is accumulated with this home made AC?
hi there. none at all. that's the beauty of these systems. they don't create any humidity 🙂
Do how long it cools ?
hi. it varies a lot depending on how fast you run the fan. (plus other factors like how hot the room is to start with, how much ice you use or if it's just cool water...)
Where did you get that solar panel from?
hi there. that's a renogy panel from amazon
Have you heard of thermosiphon? You can eliminate the water pump by thermosiphon.
I love these ice chest spot cooler videos...I had no idea how many "experts" in Thermodynamics also troll UA-camrs when they're not doing dynamic work with hot and cold stuff...
You could have purchased an inexpensive window shaker, your device will work until the ice goes away huh?
Keep the lid on the cooler, your ice will last longer.
The point is to move heat from the room into the water... It doesn't matter if this happens through the radiator or directly.
Is this meant to only cool 1 room or does it cool your whole house
An answer from an observer...It all depends on the fan and how much CFM volume it can push with the available cold water running through the system..Both are limited... to the amount of ice available and the amount of cubic feet of air the fan can push.. The previous video I saw he showed a 20 degree drop between ambient/cooled air... but this was also at the lower areas of the room which has cooler air too (hot air rises)..My guess is its limited to the CFM.. but I suppose if he put the "concept" high in the room and had a way to constantly feed the water bin with ice jugs to replenish the cold it could gradually bring the "whole" house temperature down...
@@kevinrehberg8758 Should do the trick for my stealth campervan and my woods camp. I can make all the free ice I want at my warehouse (free electric) which is a quick 1/4 mile from my warehouse. Florida summers are brutal and I know condensation coolers are useless here. Cheers

السلام عليكم شوف العمل مالتي واستفاد من التبريد
You do realize that you put more heat in to your house by freezing the ice that you lose by melting it, right?
hi. i hear that concept from time to time so here's my take on that...i get your point, but that only applies theoretically in the specific circumstance that the cooling unit and your freezer are in the same space your trying to cool, it's an enclosed space, they're both running simultaneously and the heat and cold are being dispersed equally. in most real world cases (like freezing the ice at night and using the unit during day) or at any different times then when you're running it negates that. also if freezer is in a different room, downstairs, outside etc... changes the equation. an example...say my bedroom is hot. what do i care if the kitchen is 1 degree warmer when it's freezing the ice in the afternoon or anytime really. the heat that the fridge produces will just rise to the ceiling and up thru the attic and out. my point is there is almost no scenario where this won't cool an area of your house. but again i do get your point. if the cooler is meant to cool your entire house (including the kitchen) at the same time the ice is being frozen they can cancel each other out. hopefully that long-winded answer will be of help to anyone who reads it :)
Is it just me or does he sound like he could do the voice over for south park?
Douche bags like you discourage creative minds. He did a wonderful job, and it is 1000% better than those other diy twat coolers.

@@desertsun02I have just spent about 2 hours watching all of your videos. I am going to build 2 of these units Tuesday. I applaud your talent and I too am a off grid sort of person (see my vids). I have access to a river down here on my property in Crystal River, Florida. While the average temps are 95 degrees, the river temp is always about 55 degrees. I was wondering about looping into it to eliminate the ice chest all together... just didn't know how well 55 degree would allow for cold output from the exchanger. Another thought I had was looping into the outdoor cool air blower unit you have constructed. That water also runs about 55 degrees but would literally be very close to pipe into and would also eliminate the ice chest requirement. It could also provide a water reservoir source for multiple blower units to cool more than 1 room at a time. Please let me know your thoughts. Keep up the excellent work.
