- Deluxe DIY AC Air Cooler! Best DIY Ice-Based Air Cooler i've ever made! Combo Air Filter/Air Cooler! w/internal radiator! AC/DC Powered (12v 3amp 36 watts). can be solar or battery powered. works great in a car too. (on the 12v power socket). The Unit: air is pulled into the unit through a filter and pre-cooled. the internal radiator is cooled by the ice water and by the cold air in the cooler. the high performance 12 tube 120mm radiator that's used has a thick or 'tight finned' configuration for maximum cooling. and the "internal radiator" design means that all condensation stays contained in the cooler. very little water needed (only 1 gallon) - or about 1 inch deep in the bottom. start with pre-cooled water from the fridge if possible. once you place the frozen gallon ice jugs in the air cooler the water will raise up another inch and fully cover the pump. the unit works amazing! tested in an 80F(27C) room. cool air lasted 4 hours using 2 frozen gallon jugs and a couple of ice-packs. add 2 more jugs and you might get 8 hours. *solar power options are also shown in the video (along with a homemade patch cord) so you can easily attach the cooler to a 12v deep cycle battery or a 12v solar panel).
⭐ Parts List and details on the build listed below.⭐
✔ Note: a bilge blower motor (or automotive ac/heater blower motor) is required for it to work. regular fans lack the needed power.
✔ Note: the only extra thing I'll be doing is adding caulk all the way around the radiator for a perfect airtight seal.
✔ Note: the unit is no louder than a box fan (on medium speed). i can't hear the blower motor at all when I'm running a box fan next to it.
🟢 List of parts:
1.) Igloo ice chest (38 quart with wheels and tow handle) (from walmart)
2.) SEAFLO 3" in-Line Marine Bilge Air Blower 12V (amazon/ebay - only $15 if you price around)
3.) 3 in. x 8 ft. Flexible Semi-Rigid Aluminum Duct - dryer hose
4.) Three 3" worm gear clamps
5.) 8148 Spectre Air Duct Mounting Plate - high impact ABS plastic (found on amazon)
6.) Filtrete 20-in W x 30-in L x 1-in Washable Air Filter (found at lowes)
7.) AGPtek 12 Pipe Aluminum Heat Exchanger Radiator for PC CPU CO2 Laser Water Cool System Computer (or similar) (found on amazon)
8.) Mavel Star 12 Volt Small Mini Submersible Water Pump 63 GPH (or similar) (found on amazon)
9.) AC/DC transformer (5a or higher is best) (found on amazon)
10.) 12V plug (found on amazon)
11.) Velcro
12.) vinyl tubing
13.) piece of 2x6 lumber
14.) optional: caulk/construction adhesive
⭐🔨 A Few Important Notes on building it:
Make your unit as closely as possible to this unit. Don't skip any steps. Everything was done with a purpose in mind. A few examples: use the Velcro under the wood and on the radiator. it provides a 'cushion' between the plastic, wood and metal and absorbs any vibrations that might otherwise cause unwanted sounds. circular holes can be 2.5 inches to 3" inches in diameter. i used a 2.5" hole-saw. don't cut the air inlet any bigger than 2.75". the air restriction helps the unit work correctly. (my unit has a 2.5" air inlet hole). use the 2x6 piece of lumber. the motor needs a solid base and has to be at that specific height to allow for the proper 90 degree bend in the hose. the height also allows for enough room under the hose so that the air can enter the unit properly. definitely use the 3" flange. it's needed to hold the pipe securely in place. drill 1/16" pilot holes in the
plastic (before screwing on the flange). 1/16th may sound small but plastic is "soft" and you want the screws to grab very securely. only use a blower-motor. desk fans and computer case fans are much too weak. make sure to use a "mini pump" like i did. they run cooler than a regular sized pump and the ice will last a lot longer. the connection on both the radiator and the pump is 3/8" so all you do is press the hose on. you don't need any kind of adapters.
Finally a cheaper version of the icybreeze. I think I am gonna have to try this. Thanks for the awesome content.
hi there and thank you! yes, indeed! a lot cheaper for sure. the units that they sell are waay overpriced. you can easily make this one yourself and save BIG money (plus if anything ever goes wrong with it you can easily fix it). if you buy a unit and it breaks down you have to buy a whole new one (and i think they sell them for $300)
Genius, I live in CA, my daughter lives in Dallas TX, she has a critical ill child who received a organ transplant a few months ago, her biggest concern is how to keep her space cool during a power outage, YOU ARE A LIFE SAVOR Thank you for sharing....
As a Texan, I can confirm our grid sucks. When it failed during the freeze a few years back, around 200 Texans died. It's an embarrassment we're not tied into the grid because of our yeehaw politicians helping the power company CEOs.
I've built something similar. I used a sprayer pump & it's outside of the cooler. The only things inside are ice, water, intake tube & output sprayer/ mist nozzles (at the end of the output tube, which uses a T joint to branch into 2 tubes with a mist nozzle on each end).
Got the idea to put pump on the outside and use mist nozzles from another channel. The mist helps cool the water just before it hits the ice and/or water at the bottom of the cooler.
Man i'm amazed with this channel. Even though i have recently discovered it through the cinderblock furnace video, i find it inspiring that you are still posting. I have been for the past years getting away from plastic and mass produced thrash, and these videos are helping ven more with that. Thanks.
hi there. i'm glad you found (and like) my channel. i plan on posting videos for many more years to come. most of the videos i make are the "timeless' or evergreen" type so they stay relevant for decades. feel free to comment on any of them. i see all the comments. i actually still have almost every project i've ever made.
Here recently in TN, temps are hovering near 100F and humidity about the same. Our central AC is struggling to keep up, this is a great way to help ease the load on the AC without using window or stand alone AC units. I have 500w in solar panels and 125ah in batteries. I will be putting a cooler like this together soon for the main living area. I always appreciate that you show step by step how to do things so we don't have to guess how you put it together.
By using solar or a solar charged battery (even charged elsewhere), to power devices that need it, combined with your ingenuity - WOW! Then add the bathroom sink - Super Capacitors. Double WOW! Great work!
Been years that every summer and every winter il check you videos and i try to replicate them :D you are the only reliable channel on YT that actually does awesome DIY cooler/heater !
hi and thank you. i highly recommend this one - if you're interested in DIY Cooler and Cooling. it's working so good i can't even believe it. it's the internal radiator and blower motor combo that makes it work so well. ...and at only 36 watts (3 amps) - super low wattage. this would be a great one for cars and trucks too. 12v power socket in an auto is usually rated 15 amp. just put one on the side seat or one or two in the back seat and you're all set.
@@desertsun02 i will replicate it for the bed room and hook it up to solar panel plus battery that I already have thanks a lot for the fast reply 👍 and keep it making more and more heater/cooler ! Can't wait what you will do this winter ! Cheers
I separately came up with something very very similar, but I have my water pumping through a thermoelectrically cooled aluminum block before it hits the radiator and my radiator is mounted at the inlet instead of the outlet, keeping my ice and icepacks cool for up to 48 hours. I used flex glue after silicone ruined my week and it worked beautifully.
Your design is the closest I've found to mine so far. Very cool.
can u explain more of your setup?
@@fdhall Sure!
It's very similar to this design, but my inlet is on the side to pull the cooler air from closer to the ground. On the inside, flex glued to the inlet, is my 9-pipe radiator, connected to the aluminum heat exchanger mounted to the lid. The exchanger has two small thermoelectric modules adhered to the block with a heatsink and a fan facing upwards to redirect any heat generated away from the inlet. The modules and fan are running off of a 12 volt power supply, allowing some control of the cooling effect. The cooled water is pumped directly into the radiator at the inlet, actively cooling the inside of the cooler. On top, I have a rotating duct I insulated with a cheap piece of foam and a thick table topper, with a 4 inch, inline fan running the show. Inside is a silicone container I use as my reservoir. I lay thin icepacks across the bottom of the cooler, set the container on top of those and cover it in ice before layering a foam sheet across the top for further insulation. The ice melts within 24 hours, but it all stays very cool for up to 48. When it starts losing efficiency, I pump that water into an evaporative cooler and restart the process.
Switching the reservoir into a container instead of just the bottom of the cooler and actively cooling with the aluminum block and radiator vastly improved its overall efficiency.
@@johnmcdevitt4750can you make a video just showing it? Doesn't have.to be talking I just want to see it cause some of the stuff I'm confused by the description but it's probably just the way I read
This is one hell of a design !!! 👌
yes, indeed. it might be the best one i've ever made.
Great job. I have all those pieces. And a portable freezer to turn the water into ice off a solar panel and eco flow. I watched a bunch of vids. Decided your set up would be best. Glad to see how well it works. The filter, i was not aware of at the time of purchase. Seeing yours seems like a no brainer. The Y adapter is also a must after watching your Vid. 4 inch inline fan besides increase in airflow also seems like the best. The 3 inch has a higher pitch, which to me was slightly annoying. Wonderful build. Congrats on winning the air cooler wars
hi and thank you! this unit is definitely one of the best air coolers i've built. it's been working fantastic. i'm glad you're building it! that's what it's all about.
What an on time diy project.
thanks. i only wish i could have gotten it posted earlier. didn't think of the idea until first week in August though. (and 3 weeks to design and test it)
I just built one of your other ideas and I def wish I would have seen this first. This is definitely an upgrade
Nice one, definitely a winner for a lot of peeps
hi and thanks! I hope it helps a lot of people.
I bought the cooler, ordered all the rest on Amazon, can’t wait to build this. This is the best one I’ve seen for no humidity. 12 volt I can plug into one of my power stations and use solar. This will enable me to save a lot on running my central a/c system. Thanks for sharing!
i'm glad you're building it! it is one of the best i've ever made. i'm not sure if your power station is a jackery, but this unit should work great with those and ones that are similar to those. i think the 12v socket on those is 10 amps so you could run up to three of these units if you wanted too.
I've got an A3 Bluetti, a 180 Bluetti, an Allwei 1500, a Grecell e2000s, some Ryobi 300-watt inverters with 40-volt batteries, and a few others, most all of them have the 12-volt socket, also 2200 Predator inverter generator, a buttload of solar panels I'm starting to use every day now. In the mountains in CA PG&E was killing the power all the time during wind events, during one of these fire wind events when fire danger was really bad the State of CA decided to do a backburn right next to my town with a few inmates, they lost control right away, so the story goes and since all the firefighters were fighting the fire 30 miles away, most of them came home to ashes a few weeks later. Another Maui-type planned event. I am in TX and I know from past experience we must have some alternative forms of energy and ways to stay cool off the grid.
Your invention really helps a lot of us. I like you have a list of what you used. I've sent your video far and wide. You saved me a ton of money as I was getting close to buying a DC solar mini split. This, or these rather as I will build at least 2 of them will save me from using very much solar. I'm hoping I can get a bunch of people making these, thereby using all the solar power savings to run their freezers and fridges. With the mini-split, I'd be devoting 1200 watts alone and would need a huge amount of power storage to run after the sun goes down. This uses a fraction of the power so a medium-sized power station could easily run it all night. running for a week 24-7 your's uses 5.8 kWh, that's $0.96 cents at 16 cents per kWh. That's a hell of a lot of savings for the investment. If y'all want your ice to last a lot longer make saline water with some salt. Those frozen packs you get when you order frozen or cold foods online last for 2 days because of the salt in the frozen water.
@@TheSusu125Hello! I was wondering if you could share what the total cost was for all the parts? 🙏
That's outstanding. About one eighth the price of a portable dc air conditioner. Yeah, you have to put ice in it, but look how much cheaper it is!
Thank you for sharing these creative gadgets. This is an excellent DIY cooling unit.
hi and thank you!
The plans just keep coming. Thanx Friend.
Many Many Thanxx.... I will follow your guidance and apply this to my workshop..... Again Thanxxxx !
I built this as exactly as you shown and I took camping is freaking amazing
that's awesome! 🙂⭐
This one is very good. That fan is moving a ton of cold air!
hi and thanks. yes indeed!
Wow! Another fantastic project! This one's a winner!!
thanks tom. glad you like it. i'm super happy with the way it turned out. the internal heat exchanger and blower really make this one crank out the cold air. and at just 3 amps.
Great video. The best one you made so far but there all good. I have a question.. what would happen if you put a 2nd heat exchanger in cooler. The 2nd one being under the air intake. That way no ambient air would come in to cooler just air that past thru the heat exchanger on the way in..would that
possibly ler ice last longer?
Move the heat pump to the supply opening, and install a horizontal partition a few inches below the radiator to separate the "wet" zone (water and ice) from the "dry" zone (air and radiator).
My thoughts exactly, I'm going to try with a second radiator below the intake
Amazing! Wondering if putting some sort of Reflective Aluminum Thermal Insulation at the bottom or walls could make it even more efficient.
Best video I’ve seen on this
Hi and thank you very much! I spent a lot of time designing this unit to make it one of the best "ice-based' air coolers I've ever made.
Question: would it be cheaper and simpler to mount the fan directly/vertically to the outlet port on the cooler? Might’n it eliminate condensation on the flex hose too? Thus, any condensation in the fan would drain back inside the cooler. Also, with the fan mounted to the outlet port, wouldn’t the lid now allow for a larger intake/filter port not only to give a larger filter area, but also to reduce the head force required by the fan? These are only a few questions/suggestions that come to mind. Make no mistake, you’ve done a brilliant job, and I’m ordering the parts today to make one of myself. I plan to use it in my insulated ice fishing shanty that I use in the summer for camping. I like it cool in the tent while I sleep. Cheers!
well done sir, a long time follower
hi. thanks and thanks for following!
Curious on what could cause the unit to begin with blowing cold air out then just cool air after 5 min. I clone your system including 2 gal frozen water jugs along with 4 frozen water bottles, with adding only 1gal of water. 48deg right at the start and then 60 deg after running a few minutes. Outside temp is 86 deg. Appreciate any advice. Edit: I realized that the fan was sucking in the air that is in the void in between the top lid. I used aluminum AC tape to close those gaps and now it’s running like a champ!! Hope this can help someone else out.
awesome! i'm glad you made the unit. it's one of my best for sure. 48F is awesome temp. (so is 60F really). that is pretty cold air. i'm glad you found the fix. i've got my unit cranking away right blowing (blowing on me as i type this). it's a hot one today. i think they are calling for 107F
All it needs now is a remote control! Dude you keep improving! I’d like to be able to adjust the fan speed.
hi. you can easily add in a fan speed controller. i've hooked those up to these blowers before. they sell some good 12v controllers for fans and blowers on amazon. a 3 amp one would cost about 7 dollars. it just hooks inline.
Other than the noise I really love this build.
hi. it's not as loud as it sounds. my camera just has the dual built-in microphones installed right under the camera lens (in the front of the camera). because of that it records the sound as if you're putting your ear right up to the unit. *it's actually no louder than a box fan on medium or high speed. i've fallen asleep with my head right near the unit a few times already. but if you want to make it quieter you can lengthen the exit tube on the front of it. the tube acts like a muffler (so the longer the tube is the quieter it is). another way is to use a 4" blower motor instead of a 3" one. the 4" ones are quieter. or use a different motor (but make sure it has the power of this one) because you need the power for the right amount of airflow
@@desertsun02 Thanks for the reply, will definitely reconsider this. I built the ice in foam box using a fan before with poor results. I even tried the copper wire in front of the fan method with better result but still not great. I hope this method will prove to cool down my room much better
Very Impressive...Please keep those videos coming !
you bet. glad you like it. ✔🙂
Living in Phoenix we have pretty hard water, do you use distilled or filtered/bottled water for your air cooler to avoid scale build up? Also, to clarify, the diameter of the 2 holes you cut in the top of the cooler are both 2.5 inches in diameter, correct?
Question good sir. What if the liquid used inside is coolant? What happens?
hi there. i couldn't say for sure since i haven't tried it but my first thought is whether the pump would hold up.
Great build but I would put the radiator over the inlet instead of the outlet so the hot air doesn’t melt the ice as fast
Very Coool...
yes, indeed! 🙂
So just to clarify, the diameter of the 2 holes you cut in the top of the cooler are 2.5 inches?
I wonder what the power cost to efficiency benefit would be for using a 12V powered cooler instead of a traditional one. I'd imagine it'd be worth a shot!
Would it be better to put the radiator on the inlet?
The amount of hot air that gets sucked into this, does the ice melt pretty fast? Is there another way to get that cold water to the radiator, like a water chiller?
hi. i usually get several hours before the ice is melted but that varies based on how hot the room is, how much ice you use, even how cold the ice is (- 20F ice will give you much colder air for longer than +20F ice). the ice i use is typically frozen down to 0F. if you live in a lower humidity area, you could pair this with one of my evaporative based 'water chillers' those things are very powerful and could be used as the cold water source. putting the two things together basically creates a two stage evap cooler. i've got a couple of vids on that too 🙂
Where’s the new videos dude you make some great DIY videos! Got anything I could use here in humid Florida?
hi there. if you're interested in air coolers, the air cooler in this current video is one of the best and works great even in humid climates. note: it's the "non-ice-based" air coolers (like the evap/swamp coolers) that don't work in high humidity. the "ice-based air coolers" are a 'phase-change' air cooler so they don't add any humidity to the air that they are cooling (and work well even when the humidity is high). my next two videos are an atmospheric water generator (AWG) and a Peltier Powered space cooler. the AWG extracts water from the air so it's great for humid areas (the more humid it is the better it works). and the Peltier Powered air-cooler should work well in Florida too. the peltier video will probably be posted first (in about a week)
Would this cool a general aviation cockpit like a Cessna 182 or a Piper Cherokee? The cockpit is, I think, a little smaller than an auto sedan interior. If I were to build it, I would plug the power source into the cigarette lighter, which is on a 10 amp fuse.
Very cool video, thanks for sharing, God bless !
hi and thank you!
So I experimented with putting the radiator over the inlet and the outlet and I actually get better results putting it on the inlet. Next I’m going to get a radiator long enough to go over both the inlet and the outlet simultaneously and see what that does. It also reduced my humidity by about 15%. I’m thinking as the air super chills over the radiator it’s causing some condensation thus “drying” the air before it exits the unit. I also add a small amount of H2O2 to help keep microbes and algae to a minimum.
hi there. i'm glad you've made the unit. sound like some interesting experimenting. yep, any condensation on the unit is water being pulled out of the air. (not as much as an actual air conditioner) but some. *one good thing about the "ice-based air coolers" is that they don't add any humidity to the air. that's because they are 'phase change' air coolers (meaning they cool down the air as the ice goes from a solid to a liquid). the other main type of air cooler is an evaporative air cooler (otherwise known as a swamp cooler). those don't use any ice at all but instead they use water and wet pads to cool the air.
Very interesting. Does it cool down a whole room a bit after awhile. Or are they only to feel cooler when sitting right up close beside them
hi. this unit can be used either way. it pumps out a lot of cold air and should easily cool down a smaller room with no trouble.
@@desertsun02 thanks. Very interesting to see all your different designs. You do great job of creating. Also you do a decent of of explaining too. Cheers desertsun02
Excellent 👍 !
Heyyy the vid was great I decided to copy your older vids with a bucket one tube as a vent and a 30 w desk fan my problem is the fan loses a lot of its force when the lid goes on I have the fan facing down in the lid and the tube also in the top of the lid should I have more than one tube to allow the fans air to leave I’m worried the air is flowing back toward the fan slowing it down.. I’m a novice any help would be great 👍🏻
Thanks again
Did you cut the 3 in x 8ft flexible semi rigid duct or did you use 2 separate ducts (one in front of the air blower and one behind the air blower)?
hi. i cut it 👍
Hello friend,
I was going to buy one of such cheap portable air conditioners, but at checkout the purchase failed because it was out of stuck. I have been very lucky because this event gave me the opportunity to discover your channel.
I need to make a small room in the attic comfortable and I'm wondering if there is a "no ice/cold water" solution (may be a chiller? Did you ever tried?) or the unit in this video is still the best solution. Right now, inside the room, temp is 29C° and hum 65%.
I saw your video where you used peltier modules and I was wondering if I can achieve similar performance by increasing the number and size of modules, heatsinks and fans (supposing I can find some way to vent the heated air out of the room).
Regarding the Deluxe DIY Air Cooler project, the Igloo ice chest is very expensive where I live. Can I get the same efficiency with a styrofoam box (medical grade?) ??
Thanks
hi there. I'm glad you found my channel 😎. I think that a solidly built styrofoam container could work.
@@desertsun02 Many thanks. I'll try to get a second hand ice chest to stay on the safe side.
I have found that the hot air that is cooled melts the ice fast. Am I missing something?
This is a really good one. I might try it out.
Just wondering if you put a speed controller on the fan to slow it down will the ice stay cooler for longer or is that something that needs to be regulated at the water pump?
hi. you're right. you can just hook a fan speed controller to the fan. that will make the ice last longer (a lot longer if you slow the fsn down a lot). amazon sells lots of 12v controllers and they are super easy to hook up.
I have to choose to mount this one or the one with the 22 inch fan on your other video. Which is the best 🙏🙏🙏
Apart that really cool video 👍
I think you could improve the design by putting the radiator in front of the fan, like a car. Then the air is "pushing" thru the radiator.
Rather than "pulling" the air thru the radiator.
Very cool!
Would you say this design is better than the previous version with that tubular radiator?
hi. i can't say for sure but i can tell you that this air cooler is producing some of the coolest air temps i've ever gotten. it's one of the strongest air coolers i've made. 😎⭐
Does the size of the radiator matter. I have a larger one for another project that I never used.
hey there. the size (and type) of radiator definitely matters (but a different radiator could work very well too. you'd have to experiment).
Could you please help me understand why it's important for the air inlet hole to be smaller than the air discharge hole. Thanks!
hi. I designed it that way so that there would be some 'drag' (or restriction) on the motor to slightly slow down the airflow. i figured i could expand it or add another hole or two if need but it worked out great with just the one inlet
I’m really curious how well a Peltier module would cool down the water instead of using ice. Your system with a Peltier module would be great.
Well, I think it depends from how many modules are needed and for how much time they need to run in order to keep the water cool. In theory, with copper heatsinks combined with a thermostat that power on the system only when needed (may be also a speed regulated fan?) it could work. At the end it's only a matter of power consumption.
I'm also interested in this approach before falling back to ice.
Let see what think our friend desertsun02
As of now, the best solution I found is to enhance the cooler to make the ice last longer. See my message below, but don't buy any part since I'm waiting for desertsun02 approval.
@@AlbaFunari-ex8pz yes you make some good suggestions. A thermostat would be great to only start it when needed. Of course, if adding a Peltier module, you'll need an exhaust fan to expel the heat from the heated side. Ideally, you'd want to expel the heat outdoors if possible. Complicates the original design but I think it's doable. I just don't know how cold water can get from a Peltier module. I was thinking of powering the whole thing with a solar panel just like desertsun02 mentioned. Maybe a 100W (or 150W) panel would be sufficient.
Do uou prefer rhis style ir the transmission cooler on top? Any issues with condensation blocking the radiator?
i don't generally have any condensation where i live (because the dew points are usually low) but one good thing about the radiator being inside the unit is that if any condensation does occur on the radiator it will just drip down into the water below. the airflow through the radiator is strong so the condensation won't block the airflow (in any noticeable way).
Do you think this would cool a hot garage in brutal Texas summer heat?
I applied your methods and an impressed with the results. I noticed that operating in a workshop that exceeds 105 degrees that the exhaust temp is as well as one for the intake round 65 degrees. I have considered a secondary radiator to the exhaust and a radiator for the intake air. have you tried these to bring the temp lower ? .... Many Thanx for your imput.............
Another question…. So I have two of those window fans, about 12 x 26, has two small fans, I’d like to make the cooler, pump, radiator rig in front of the fans, to run them across the radiator, blow cool, fresh air in.
hi. it could work but you'll have to use a more standard style radiator with the wider fin spacing. a window fan wouldn't be strong enough to pull much air through the type of radiator i used in this project. i'd try something like a 'hayden transmission cooler' (radiator) with a window fan. i've got a few vids with the hayden radiators. they pair up well with standard fans
Have you done a comparison in runtime against the other unit you built with the transmission cooler on top, with the same amount of ice, i’m guessing the reason this unit is colder is because it’s pulling air through the hole. It goes across the ice, like a swamp cooler, then goes across the small radiator which causes the air to be colder. Also, the velocity of the fan is reduced due to the bends in the hose, which would cause the air to be colder
hi. i haven't done a comparison of the two but i think it helps that the air is precooled across the ice, before it goes through the cold internal radiator. that is also dual cooled (my ice water and just the fact it's inside the cooler. overall, this unit seems to have a very high efficiency. it definitely gets the coldest and lasts a very long time. ...btw, there has been some confusion online lately about what a swamp cooler is, so this last part is just a note about 'swamp coolers'. there is an advertiser out there that has been calling the ice-based air coolers 'swamp coolers'. they are misleading a lot of people. the term swamp cooler' is just another name for an "evaporative cooler". swamp coolers don't use any ice at all. they just use 'wet pads' and water to cool the air. the ice-chest air coolers that use a fan to blow air over ice aren't swamp coolers. they are just "ice-based 'phase-change' air coolers". ...and like the unit in the video, those units don't make the air sticky or humid either. that's because when you blow air over ice it just melts from a solid into a liquid (but it doesn't evaporate - so no humidity is added to the air).🙂
Amazing!🎉🎉🎉
Oh so cool! 😊
hi and thanks! coolest one in terms of temps and looks pretty cool too (imho)
Are you planning to do an indirect evap cooler with this type of radiator? Wonder how it holds up against the other type of radiators you've used in the past.
'ill give that idea some thought. i hadn't thought about that.
Hi!🎉🎉🎉
Would it be possible to make a small tankless water geyser from your design of solar panels + a couple 30w ptc heat elements + a copper tube with copper sheet?
In a previous video a while back your design got the copper sheet over 200c in about 10secs.
So im thinking water should get 60C easily ?
Thanks🎉🎉🎉
i'll have to think about that one. i've got ptc water boilers so they can get the water pretty hot.
Will this setup cool down a grow tent? And have you ever thought about using a thermostat?
hi. it's a pretty strong unit so it should be able to. i hadn't thought about using a thermostat before. should be an easy addition. amazon sells the 12v ones cheap.
So cool, does this set-up create allot of humidity? I just ordered all the parts to make your inline transmission cooler A/C.. Thank You so much for sharing these awesome ideas, much appreciated! Great channel...Do you think a 24" Transmission cooler would cool more than the 15" since it has more surface area?
hi there. this type of unit doesn't create any humidity at all. the cold water in the unit cools off the radiator and then the air in the room is pulled through that cold radiator (cooling it down). the process itself doesn't evaporate any water so no humidity is added to the air. an interesting sidenote is that condensation sometimes builds up on the radiator and when that happens the unit is actually pulling water out of the air. (so it actually removes some humidity from the air), not as much as a regular AC but some.
The bilge fan blower... is the speed adjustable or is it an ON/OFF switch?
hi. it's just on/off but you can easily add a 12v motor speed controller. amazon has those for just a few dollars. it just drops in-line.
I purchased the parts for this project and built one. It's working so far, but the air blowing out is severely reduced. Per the instruction, the inlet is 2.5" and the outlet is 3". To test, I open the cooler lid and the air that comes out of the air blow is much higher so I know more air should be coming out. Has anyone run into similar issues with restricted airflow?
hi. i actually designed it that way to reduce the airflow, but it should still be coming out pretty fast. you could try adding an additional inlet hole or two, but i'm not sure if that would negatively affect the cooling power of the unit.
Last question Can I use (inline duct fan) exhaust fan like the Brogachy Extractor d'air 100mm for exemple
hi. i'm not sure about that specific fan (but the main thing is to use a powerful fan - like the blower fan i used). it has to have a powerful motor for it to be able to pull the air through the type of radiator i used.
Man it's gonna snow 🌨️ in your house 🏠 😂
But for how long??? Plastic don't dissipate the cold than the aluminum, how about the drain amps x hours, the plan will be a battery bank to will run from 10 pm to 6 am, a design don't build mold in an RV or van, I have an super quiet inverter with an ac window 5,000 but looks from the ghetto plus the noise and I will like stealth a.c. sistem, here in Texas then humidity is killing
what would you guess to be the effective running time for the 2 gallons of ice?
about 4 hours (with room temp in low 80's (f). maybe even 6 hours (but it would just be kind of cool at that point, not super cold). if you added another jug or two or some ice packs you might get 8 hours or more. another way to extend the run time is to add a simple fan speed controller. very easy to add one of those and if you run blower at half-speed you might get double the time. amazon sells 12v fan speed controllers for as little as 7 dollars.
So is it a swamp cooler? What is it? Does throw it humidity back into the air?
hi. it's definitely not a swamp cooler. the term 'swamp cooler' is just another name for an 'evap cooler'. evap coolers are a type of air cooler that cool the air with 'wet padding' (but they don't use any ice). the 'ice based' air coolers are called 'phase-change' air coolers. they cool the air when the ice changes from a solid to a liquid. the ice doesn't turn into a gas though (it just melts into a liquid) so the 'ice based' air coolers don't add humidity to the air. (they just cool it)
Another question ~ you may end up saying this but what about humidity? It’s already so humid I’m running a dehumidifier.
hi. this unit won't add any humidity to the air. it even removes a little (by way of condensation that forms on the radiator and the ice blocks). any condensation is water that's being removed from the air. it won't remove as much water as an actual AC unit but any water removed from the air is a good thing.
@@desertsun02 thank you!! I’ve sent the link to my brother ~ an architect ~ begging him to build me one. We weren’t born with the same brains ~ at all!! 🤣
Good 👍 bro hme b bna dygy
My condenser fell off. The adhesive failed on heavy duty Velcro
Anyone have other methods?
hi there. that's odd. it should definitely hold strong. couple of options: you could use a construction adhesive (like liquid nails) if you wanted too. it's waterproof and very strong. that would work. you could also superglue the velcro onto the unit. they also sell something called 'extreme weather' velcro. it's 2 or 3 times stronger than standard velcro.
Could you use 4 in ducting and blower ? Os is that to big for this radiator?
i think you could use a 4" duct and blower with the radiator. i'm not sure if it would effect the cooling power of the unit though.
Question is this 2 frozen gallons of ice with water in the cooler?
hi yes
@@desertsun02 and the hose from the pump to the radiator goes directly into the water in the cooler
yep 🙂✔
@desertsun02 thank you 💯
Sir please explain the concept behind air disk technology which was invented by James Dyson awardee angel palma.she claimed that it consumes only 10% power compare to conventional heat pump system.
What did you add to your ice blocks to get them 21°
hi. i didn't add anything. they are just tap water. my freezer is set to about 0 degrees (f) so the ice will be much colder than 32. 0 F is pretty standard for a kitchen fridge
One question what is thé type of radiotor and the size.
Any information please,🙏🙏🙏
hi. the exact dimensions are 6.2" x 4.65" x 1.1" but in general they are known as 120mm radiators. this one is a 12 pipe one but i think they have 16 pipe ones too. you can find them on amazon. for even more info check the description section of this video 🙂
Thanks 🙏🙏🙏
What about a NBC filter? I need to build one asap
you could certainly experiment with different kinds of filters. i bet it would work well with lots of kinds. maybe even one with activated carbon
Was your frozen jugs filled with salt water? Interesting if there would be a difference in temp vs run times compared to just water but it will take longer to freeze too.
I experimented with something similar a few years ago with a double thick 120mm PC radiator. You can also get 240 and 360 and in single and double thickness. I would opt for the larger radiators with a Y junction. These inline fans have enough flow and pressure for it. I would also go for a larger inline fan, they run quieter but flow the same withou much pressure loss, some have adjustable speed. To run a bigger radiator you might need a new spot for the intakes, closer to the outlet may suck in cooler air which could be good for run times. If your esky lid isn't insulated, fill it with expanding foam before drilling.
hi. i just use standard tap water (no salt used). the water will freeze down to the temperature of the air in the freezer. i just have a standard kitchen fridge/freezer; but if you had a freezer that went down even farther (say to -20F/-29C or -30F/-35C) the ice would be that same temp (-20F/-29C or -30F/-35C). salt is an option too, but like you say, it would take longer to freeze.
Question good sirs. What if the liquid used inside is coolant/anti-freeze? What happens?
Have you ever powered it with a m12 battery?
hi. i haven't used one of those but you can certainly power this with 12v batteries if you want to. unit is very low power so it would run a while even on a single 12v battery. i usually use marine deep cycle, but lithium battery should work well too.
Hi, is my radiator supposed to be wet or dry. My radiator is wet. Just wondering if I got a bad one.
I think I figured it out. I think it was because of the outside Humidity. Humidity was 98% and rainy.
the radiator may get wet if the dew point is reached. but it's totally okay if that happens. the water will just drip back into the ice chest.
Testing after changing the radiator and lower Humidity. I was able to achieve 36 degrees. Whereas, I was only able to get the he temp down to 58 degrees before.
Thank you.
What radiator did you buy ? You have a link?
hi. check description section for details on the radiator. it's a 12 tube 120mm one (the exact one is listed). easiest place to get it is on amazon.
I just want to plug it in the wall
you can easily run it on wall current if you buy an ac to dc transformer. they sell lots of those on amazon.
Sure wish you made and sold these! 😂
it's really pretty easy to make. maybe you know someone who could help you?
@@desertsun02 my brother!!! ☺️
What was the ambient temperature? It would be good to compare the difference in the air temp going in and coming out.
hi. the ambient air temp in the house was 81F/27C. so roughly a 45F drop (25C drop). 81F down to 35F (27C down to 2C).
Do you sell them. If so how much?
i don't sell them - but you can make this for 85 to 90 dollars (and take $30.00 off of that if you already have a similar sized ice chest). it's well worth building if you can. i'm loving it. cools a room in minutes. the interal radiator and blower motor combination really worked out great
I need help please. I followed your directions exactly and ordered all parts to spec. I can't get the room to cool though and my temps coming out are max 55 but vary into the 60s. The cooler is filled with ice water and a steady 27 degrees inside the cooler.. I can't imagine what I am doing wrong?
hi. it's hard for me to say (without being able to see it) but here are a few thoughts to consider. btw, 55F is a pretty good output temp. that's about as cold as any regular AC window units gets. i know it's not the 35 i'm getting but there are several potential variables with these units. i'm cooling a dry input air of 80F. if you're input air is warmer, say 85 90 or 95F it could increase output temps. another factor could be humidity. this unit will work in any level of humidity but drier air is easier to cool down than humid air, so that could be part of it. if you are using the unit in 80F air then you'd need to look at things like 'is the air getting around (circumventing) the radiator in any way. is the blower running at the proper speed? is it the same radiator? is the pump working properly (or too fast or slow). are all connection tight? that's a few things to check. but remember even 55F is a great output air temp. the lowest temp i've ever measured coming out of an AC window unit is 55F. as far as cooling the room goes... give it time to cool - these units work well in smaller rooms.
My Results: EXACT Same design : Start temp: 79 degrees F. Output 45 degrees. 200 square foot bedroom. 1 hour passed: Room dropped 1 degree to 78 degrees. Output Temp after 1 hour: 55 degrees. 2 frozen gallons of Ice in cooler AND 3 Ice packs. Conclusion: Not good for big rooms! Other: pitch noise of fan sucks and annoying. Much different than box fan!
I see nowhere on here do I see what it actually cost you to build. Including what you might think you’d get paid per hour to build it.
Hi sir ,what about adding thermo electric cooler for continuously chilling the water to your system.as soon as ice melts it will stop cooling.
I need 12,000 btu minimum in my hot minbus
I have a hot minibus as well. I am definitely going to give this a try! Even if I have to aim the discharge hose right at me, it would be a welcomed relief in these Texas summers.
These vids are cool and are going to be super helpful when I build something similar. Just a slight critique on the video maybe try to find better lighting and background options when showing your work. You can show us your results with the temp gun and tell us it worked in your bedroom…. Without showing us your dusty ass bedroom. Take care
Hmmm....Seems like you could use a filter change, to increase ability to appreciate and discern the value of relevant knowledge, compared to background 'life noise'.
Great video ! May i ask what size water pump did you use ? Many Thanks !!!!!!!!!!!!!!
hi and thank you. i just use a small 63gph 12v water pump.
You didnt show room temp
Maybe for me that room temp,shows how much is diy ac efficient btw thanks its very useful video.
hi. the house was 80F(27C) at the time of filming.
I'm differently going make one.Thanks for the idea my brother.God bless
Excellent. With 2 ice blocks, how long can it last?
i'm getting about 4 hours with 2 ice blocks. but it will depend on exactly how hot the air is that's going in and how solid the blocks are frozen etc... add another block or two and/or some blue ice packs and you can get 8 or more. a fan speed controller can extend the cooling as well.
This seems awesome ... I just ordered everything on amazon except the ac/dc transformer ... I dont know what to get there. Is it possible to get a link of what to buy. I want to get all the parts and "surprise" my son with a project for him to make for me lol
hey there. that's awesome. this is one of the best. since the unit only draws 3 amps i'd say to go with a 5a to 6a power supply (or higher). i use a 12v 15a supply made by rowpow. i use that one because it's the smallest one that i have. (i've also got a 30a one). here is the link to the 15a one that i use www.amazon.com/Converter-Adapter-Transformer-100V-120V-Cigarette/dp/B0797SHG1K/ref=sr_1_11?crid=TD7EP5G3JME1&keywords=ropow+ac+to+dc+12v+15a+power&qid=1693083879&sprefix=rowpow+ac+to+dc+12v+15a+power%2Caps%2C179&sr=8-11
the best way to find these kinds of power supplies is to search for Ac to DC converters on amazon. here is a link to a smaller (5 amp) one. it should work great. it's only $14.99 www.amazon.com/ALITOVE-Converter-110-220V-Cigarette-Purifier/dp/B075FPQ2YQ/ref=sr_1_5?crid=DW3LUAP7DFKW&keywords=ac+to+dc+converter&qid=1693083950&sprefix=ac+to+dc+converter%2Caps%2C180&sr=8-5.
Thanks so much! I used your link appreciate that! Texas grid always questionable and love the idea of some back up relief! Thanks for sharing your ideas! Great channel.
