Love the mini heat exchangers - great idea. 2 things that would help the time run longer: 1) put the ice/water in a thermos (something insulated). You could notch 2 holes in the side lip for passing the tubes. 2) insulate the tubes with neoprene like insulation. With these 2 things you'll be better able to control the area cooled.
This is absolute genius, it can be easily solar powered and also turned into a heater. I will make me couple of those and spread them around the house. THANK YOU GENIUS
thats a great idea. another thing to do, instead of having the tubing inside the tub with water and ice packs, you could use another radiator and dump that in the tub with the icy water. the metal will get SO cold and act as a further cooling solution so the water will be colder when it hits the radiator with the fans on :)
I am wondering about getting an old mini fridge and running the pipes through the roof of it along with your idea. Am starting with this set up and going to expand it.
I knew a guy years ago did this basic concept but he used a closed system with a keg in a barrel of dry ice at first , he eventually put it inside a small propane fridge he salvaged somewhere.
I have even done dry ice and antifreeze on larger scale. Built a unit out of a ice chest….my liquid coolant recipe is still being worked out but it is some ratio of the following: sea salt dissolved in distilled water, antifreeze & vodka. I am still playing with configuration in ice chest but basic premise is a 3 gallon bucket with lid fastened to floor of ice chest with metal mixing bowl filled with either regular ice + rock salt or dry ice depending on the volume of air to be cooled & size of coils. In the lid I have quick release couplers to attach exterior hoses. One of the holes will be for CO2 exhaust from dry ice which absolutely must be vented if camping or in tight space as it could cause loss of consciousness. The other two ports are for the flex hoses that I insulated myself to connect to coil radiators or booster pump station. I also have a power connector on the bucket lid 24V only that way everything can be disconnected and not have to take shit apart. In the bucket I put 2 micro submersible pumps mounted on sides of bucket that turn on automatically if there is liquid even if the main pump isn’t running so that things don’t freeze by chance. Then I have main pump in the ice chest mounted to bottom of chest. Pump is actually very strong and is electronically variable via a couple ways (will go into in a bit). The big pump has a relay lead to manually shut off, automatic emergency shut down and for thermostat. I modified an old ice chest and rebuilt it into a nice looking rugged device that just has ports on outside that are labeled for various hose connections, power, data, etc. so I won’t go into the radiator/fan thing because that depends on your own situation but the idea i had with the main cooling unit is to have all the brains and guts in one place. I am currently working on having battery bank in the unit so that it can run on a charge being I intend it for camping. I am also figuring out what to do about the CO2 exhaust if there should be a pressure sensor inside the unit and a valve to bleed off any gas. So I used a raspberry pi as onboard computer with wifi and Bluetooth. It has a tiny 3.5 in touch screen that I bought as a all in one case but of course the main interface can be accessed on any browser or Remote Desktop service. The Pi monitors everything but the point of it is to maximize efficiency and to act as a smart thermostat by throttling 12v fan speeds (more electricity is wasted when start and stopping vs constant variable) as well as the big daddy variable main pump (boosters if applicable). There are temp sensors on radiator coils, inside of egress/ingress coolant tubes, in front of fan (air temp) as well as inline flow/pressure sensors and coolant liquid level sensors…I also added several sensors that are round discs of absorbent cotton should they get wet it will shut the entire system down and an alarm goes off and if it is connected to wifi it will alert on your phone because it would be horrible if a leak starts and all of coolant pumps out flooding the tent/house or whatever. Anyways I have had many prototypes going back starting 10 years ago so I don’t have a final product. I have some finished ones to get an idea of design. It sounds like this is an expensive habit but as long as you know where to buy stuff used and where to find free stuff and trash to recycle. I am an engineer so the #1 step is to put pencil to paper and just start writing down ideas and sketching out some design ideas! Start very loose then start drawing out designs on some graph paper then go to computer to do some drafting, 3D modeling mock-ups with exact numbers shapes and lines, etc. it is easy to change the design in digital form and you can get exact measurements before building or buying the first thing. You can design anything when you know what you are doing with the right tools and software and computer science/coding/it skills. Learning AutoCAD (free open source alternative is called LibreCAD) & Google Sketchup Make (free) will start you on a journey of making a lot of money and solving tomorrow’s problem’s! I am working on modular design style and way of building underground in-hill tiny home off grid 100% self reliant & sustainable mini homestead with all the technology we are already used to, just more efficiently and healthfully! Stay tuned because you will hear of this project in the next decade. There is a whole team of us all over the world volunteering our time to engineer new technologies and community models that will address the human rights crisis seen all over the world.
Love your experiments. I can tell you are not married, as no wife would allow the pieces of your previous experiments to be set around (like under your table and beside your bed). They typically ruin fun stuff! LOL
LOL now, that depends on the wife, my house resembles a workshop, and I'm on a promise to clear the kitchen as I'm using most of the work surfaces with projects! TBH I think she's given up nagging...
I've ordered my parts to make this I've a quiet running fan that I've had in the garage that I got given a couple of years ago and never used it till now .. and I've ordered a coolbox to place the pump and ice into .. my partner just said to me what the fuck are you making now ! Lol 🤣 it's for her Benefit .. and mine
Might work Great in DRY CLIMATE..... Humidity requires a tray under the coil if dripping. If air velocity is fast enough though and humidity is reasonable, then there will not be enough Resident Time on the coil for moisture to condense out of airflow. Slow down airflow to Dehumidify. Increase airflow to flat out Cool ... there is a balance required for True Air Conditioning effect involving Dehumidification and Cooling. Same principles apply to full blown Central Air.... if insufficient dehumidification is occuring then you need look at Blower Speed setting. BUT BEWARE of EXCESSIVELY LOW SPEED AIRFLOW or Clogged return air filter resulting in similar low airflow condition which will cause Ice to form on Evaporator Coil and lead to System Damage if liquid refrigerant makes it way back to the compressor outside. YEAH... Went on a bit but point was to make comparisons and Educate.
Thank you for sharing your time and these encouraging results. I had this same heater core based idea cross my mind over the past couple of years, after watching a video featuring a cold copper coil zip-tied onto a box fan. I knew we could do more efficiently. You have given me confidence now to actually spend money on my own compact design without worry. I propose a version that has the coolant sealed inside a vessel that can fit fountain pump in the opening, like a half gallon mason jar, or something. I also propose using cheap vodka instead of water. The Russians historically used vodka as a superior coolant in some of their older military aircraft. This way you could drop the vessel into the bucket without needing to worry about priming the system before each use. Thanks again
I made one of these a few weeks ago using a transmission oil cooler with a thick walled foam cooler. (Like they ship lobsters in) I mounter the fan with the heat exchanger onto the lid and drilled holes for the input and output lines to go into the cooler. I stuck in 4 large ice blocks (Made from freezing water in qt. size potato salad containers) and had my 4w adjustable output pump set to the lowest setting as was my fan and the air off the fan was 54 F. Nice and cold. My problem was, all the ice was gone and the water was room temperature (85 f) after only 45 minutes. My heat exchanger is too efficient I think so I need to restrict the water flow through it. If I could get 68 f air out of it I am sure it would last much longer. I still have more experimenting to do. I am using this in a small bedroom that does not get much of the ac from the heat pump.
hi. options to extend ice and cold water are smaller heat exchanger, slower water flow, smaller pump (big ones can heat the water), and one big way to extend times is to use a speed controller to slow fan even more. the slower the fan the longer the (cold) will last. i got 11 hours once on a 3lb block of ice in a foam cooler. fan was really slow but it was cool enough.
Brother DS02, Great movie!! I fwd this to a couple ppl and mentioned that, if using the 5 gallon bucket method, a couple one gallon milk jugs, filled 3/4 of the way, or so, would be cheap and easy to rotate from freezer to bucket. Keep up the good work.
It's an interesting design. Although if you go 9 to 10 feet down in the ground. It's a study 50 to 60° year round. So a simple air pipe technology can augment your heating and cooling greatly.
Great build. The 5 gallon bucket with a lid and grummets to keep all cold air tight for as long and possible. Plus rap the bucket in an insulation. Boom a win win cold all day DC 12v air conditioning. Awesome.
@@sharonmetzner1798 I think he's talking about a small 12 volt refrigerator/freezer for small trailers or in his case his van. I've used them, some are propane/12volt/110 combo. freezes his water jugs in it to use in his ac system. the older ones have a small center ice tray size "freezer" that freezes and keeps the unit cold or crank it up and freeze stuff. You could use a separate dedicated solar panel for the freezer, rotate jugs during the day in the AC unit cooling container.
Just an idea. But what if you placed a second radiator submerged in a bucket of salt water with maybe dry ice packs, and the liquid going between the two radiators being a closed system. Then potentially mixing in some antifreeze to the sealed system, depending on how low the temperatures drop.
Take one of these out on the boat for a days fishing and drop the tube right in the water, keep ya cool without bothering the fish or using up the ice in your cooler 😁
The paint can is a great idea for the cooling Reservoir. Just needs some way to insulate the paint can and the lines. If you could set the cooler on the top of the can make the hose fitting be all inside the paint can and only have you wires for the fans and pump coming out the lid. Would help make the Ice block last longer inside
Same concept on how a chiller works. Air cool chillers cool the water at 55 degrees. Pumps are used to push the chill water into the evaporator coils. Blower motors push air into the the evaporator coils and cools mega buildings. Return water pumps into a water tower. Nice miniature chiller 😎
This is a great idea for a little spot cooler to blow on you for a few hours or maybe cool a bedroom! But it’s not a good solution for cooling a living space if the freezer you’re using to freeze the ice packs is in that same space. You’re just transferring heat from the air into the water, into the ice pack, then your freezer will transfer the heat from the ice pack right back into the air… and generate more heat in the process.
hi. if power grid was destroyed you'd have to tap natural sources of cold water. (well water, lake water, river water etc.) or use evap cooling technology to cool the water source. you could also tap into the natural coolness a few feet underground (run water through a pipe underground to cool it down... things like that). ...just a few random thoughts
hi there. i'm certainly stoked about them. they work fantastic and are easy to build. one more (a giant version i'm building) is in the planning stage at the moment. it's going to be bigger than all 3 of those transmission coolers put together with a 2000+ cfm air output. (for people who want the ultimate air cooler) - stay tuned 👍
@Sharon Metzner i built something close. i used two of the larger radiators (model 405) and attached them to a box fan. if interested here's the links... 1.) th-cam.com/video/Jfc26AH0jLI/w-d-xo.html (original box fan conversion video) 2.) th-cam.com/video/oAuL-ScEWfI/w-d-xo.html (extended semi-uncut version)
I’m thinking of trying this in conjunction with a chiller. It’s too bad glycol chillers used in fermentation are so expensive, but hydroponic garden water chillers are a little cheaper. Im trying to build a system to cool three heat sinks and a radiator for air cooling and spot cooling on the heat sinks that get pretty hot.
I found a 6,000btu window unit in the trash for free, it works fine and I don't need to run a freezer to freeze ice. Yours would be great if you had an ice cold free flowing deep water well.
get a large terracotta urn, aka "amphora". the seepage through the unglazed ceramic naturally cools the contents to 4C. there are charts around for the actual drop in degrees for every unit of water lost. if you have 200 odd litres of water held at 4C, you arent going to warm it up much with this set up! all about thermal mass too. its not as limited as the swamp cooler is, still works in high humidity. though of course, its better when its dry... and yeah, enclose those coolers, all the air through the fan AND the fins. the slower the air through the cooler, the more heat sucked out...
Place the bucket into a planting bag 2" or 3" larger in diameter than the bucket, then put insulation material between the inside of the bag and the bucket. Top the bucket with a round pillow or foam. That way, the ice will last much longer. I may give this a shot, Thanks!
I’ve been thinking of getting a 300-500 gallon heater holding tank. Burry it with a Accessible hatch. Run a inlet hose on the bottom and a outlet hose on top. With a pump to circulate the water throughout the house and use radiators with Fans on them to cool down our home. We also have Solar water heaters for our hot shower water. Install a Bypass to allow the hot water to also run through the same radiators in the winter to heat the house. I’m just a little worried because the hot water gets extremely hot because it’s in stainless tubes covered with glass and it gets extremely hot, maybe a Separate radiator in a isolated area and then ducted into home.
So adding a pan with a hose for drainage and insulating the can to extend the coolness of the fluid....Shazam! Also if you have an efficient danfoss-like type rv-equipped fridge (think ICECO, Whynter, Dometic, etc), you can use the freezer section to continually replace the ice packs on your small living space. These fridges use no more than 40 watt/hours, so the whole ACTUAL setup for cooling your small RV/small truck camper/camper topper/minivan/full size van is about 50 watts +/- !!! Use this for your sleeping area at night or during the day your living quarters. Maybe separate the 2 areas using some bubble/foil for maximum cooling effect.
Project looks fun👍 You could maximize cooling by a makeshift duct between the fan supply and coil. That way 100% of air the fan is pulling would blow across 100% [entire surface area] of the coil.
I would like to have one of these to cool while sleeping. For 8 hours of cooling. Was thinking of running the AC a little higher and assist with one of these. Probably would take about 20 gallons of ice water in an ambient temp of 78 to start with. I hate to go thru the trouble to find out. Also, to cool the patio to at least a bearable temp for the dogs outside. Just to humid I'm afraid in Houston. They abandoned swamp coolers back in the early 70's
hi. evap cooling definitely struggles to work in the humid areas. these coolers aren't evap based though - so they work decent in any humidity level.🙂✔
That’s a very good concept and I commend you you are nothing short of a genius but I see one small problem. Try putting a shroud over that entire heat exchanger with the fenders so this way there’s no wasted energy just try it listen to me and I promise you you’ll get a little bit more colder air channeled through that fan thus wasting no energy and putting out more colder air 😝
hi. there are companies that sell 20 by 20 heat exchangers but they are super heavy and expensive ($200+). here is one for $223 badger-pipe.com/products/20x20-water-to-air-heat-exchanger-1-copper-ports?_pos=4&_sid=7c37db64a&_ss=r&variant=29108329425
@@desertsun02 hello, I actually found a car radiator on Amazon for 30 bucks when it was on sale, but didn't really pull the trigger since I wasn't sure if a box fan could even push through it.
@Sharon Metzner box fans work. i actually have 2 videos showing how to make a unit using a box fan. works good. here's the links... 1.) th-cam.com/video/Jfc26AH0jLI/w-d-xo.html (original) 2.) th-cam.com/video/oAuL-ScEWfI/w-d-xo.html (extended version)
What if you had a mini freezer with 3 holes drilled at the top one for the pump power cord and the other two for coolant feed and return. The internal radiator then sits in a shallow or deep bath of chilled anti freeze. The tubes run out and feed the external radiators that have fans attached. This way, the coolant lasts significantly longer would it not?
It might actually not last longer because you are not taking advantage of the phase change of water melting. This absorbs lots of heat and keeps the temperature consistent which helps with giving a temporary cooling boost. If the water is cold enough then yes, it might outcompete the just ice version
What are the small fans connected to? Would an AC power supply from an old gadget work as long as it provides enough volts and watts? Thanks for the great work you do! Once again you've given me a simple solution so I don't have to reinvent the wheel. I wanted a simple heat exchanger for solar heating my greenhouse in the winter and this idea will work perfectly!
I've been watching videos for making these for 2 weeks and this is a great idea using the trans coolers. I am going to use this method and install it into a 50qt. cooler but am researching the best ways to make cold temps that last the longest balancing the radiator size with just the right amount of water flowing through it so my ice/cold water will last longer.
I am currently making one of these using a 48 quart cooler and the same mid sized radiator you used (mine is about 7.5 X 8.75 inch). I cut holes into the top of the lid for the two tubes, so the radiator sits vertical on top and its tubes go directly in/out of the cooler. Almost no tubing is outside of the cooler. The only holes in my cooler are for the two tubes and the pump power chord. However my fan is also smaller than the radiator like one of your examples (lots of radiator space around the fan not getting airflow). Do you think that is inefficient? Would it be better to enclose the radiator somehow so that it gets a more even air flow through the whole area of the radiator? I am trying to optimize getting the most out of my ice before it melts. Really enjoying these videos. This was the perfect idea to cool down my room as well as my car for road trips (AC is broken) Plus I love DIY projects like this.
hi. i'm getting one to two hours of cooling just using a gallon of water and 2 ice paks. for extended cooling times (3-6 hours) use more ice or ice paks or even an ice chest. you could double or triple the time that it will cool (even more if you use large blocks of ice). for max. times fill the bucket with water and freeze the whole thing overnight. then when ready to use just add a little water to the top and put the pump in (you might get 8 hours of run time).
Cool exprement u inspired me to copy your design but ill upgrade it by putting the water bucket in a mini frige run by a compressor just got to drill two holes for the pipes and thats it hopefully it be as good as any ac
hi. sounds like a good plan! i'm currently working on another similar unit. it will be out in maybe a week. it basically has a fancier "removeable radiator" stand (combined with a mini "table top" shop fan). it will be the fastest and coolest one so far.
To make this even more efficient; in my mind anyways, and for a larger scale use. Sink a holding tank of some sort; IBC, plastic drum etcetera, in the ground; well below grade, and cover it up. Of course you'd have to install the proper plumbing before hand. Run all that into a manifold where you could split off to individual lines for separate applications. Insulate all your above ground lines. And you could; in theory, always have sub 60° water for circulation. Right? Yup! In my mind anyways. That way you remove the need for refrigeration and ice. And with black poly vinal tubing you could go solar for heat as well. Coil up a length of poly vinal in a glass covered box and you'd; in theory, create a hot water radiant heat system. You've got my brain going now, Sir! I'm glad I found your channel again. I misplaced it for sometime but now I'm back. I'm glad you're still making videos.
hi there. good ideas. i've always thought the idea of going sub-surface for cooling is an excellent idea. if your water is even 60F you get some awesome cooling out of these devices. (i even ran plain tap water (72F) through this device and got a 5 degree temp drop with no ice or cold water at all). the solar option for heating the water (to make an air heater) is great idea too. just circulate every so often and you've got almost free heat. btw i'm glad you found my channel again! i'll hopefully be making videos for 20 more years
hi. it would depend on how hot the room is, how big it is, does it get lots of sun and all of that but unofficially, i've seen temp drops in a 10x18 room (my living room) by 5 degrees (83F to 78F). the best i can tell you is it seems to cool half my living room pretty well (so maybe 2 units would do it?) or one for a smaller 10x10 room.
I made one of these built a box around the radiator and put the fan on the out side. I built it for our work truck it dose really good but the ice melts fast. Gonna see if I can extend the life of the ice with a big cooler and some Insulating tape on the hose
put a hole in a tiny cheap fridge and put some water in it and let the water run through it so the water gets cooled in the fridge while your using it for the ac
Mennn you are amazing..i have radiator, fans, pertier plates, pump etc etc..all what you have here..still im waiting and thinking HOW TO MAKE IT!? Yess this is The System i like..thank you~♧
I was thinking about doing this for fun and looked on YT and seen your vid. Was thinking about doing exactly this. Only thing I’d prob add is a shroud to go from coils to single fan so you get all the use of the coils. 2 fans is cool too but in my mind I’m thinking I don’t want too much flow or it would raise temps
Could you show a list of parts you can buy online like Amazon AND a step by step instruction for beginners please? Will this work in a van? How much square footage does it cool or do u have to sit in front of it?
hi there. the list and build are in the last part of the video. it's super easy to make. it will absolutely work in a van. since the unit is so compact that is a great use for it. 👍🙂
Have you ever thought about taking a refridgerator or a deep freezer and removing the doors and sticking a large box fan in front of it to see how long it would take to cool down a room such as a garage or a kitchen etc
How about compressor free absorption type refrigerator and air-conditioning using induction as heat source, they are starting to discontinue 3 way refrigerator in RVs ?
hi there. yes that happens with high humidity. units typically still work well though (plus the condensate is water being removed from the air - so that should help the air feel better too)
I'm thinking.use your trans cooler as in this video. If you have a 12vdc travel refrig freezer.put your cooling lines through the horizontal hatch cover with a type heat exchanger in the cooler. How much water do you put in the bucket to supply your chill lines? Any ideas.
hi. i decided to jump right in 'to the action' with this one and i put the items list and build at the end. it's just pumping cold water through a heat exchanger to produce cold air - nothing really complicated. feel free to ask any questions. (posting them as a new comment is the best way to make sure i see them. i'm not always notified about replies)
hi. the square fans are Axial fans made by AC Infinity. amazon has them. both the low and the high speed models are 4.7x4.7x1.5 in. (120mm). model numbers are LS1238A-X and HS1238A-X.
Been following your progressin on these units, like your work, i have most everything i need to build one, but for me its a must instead of a project i have an older peterbilt truck that i have to drive this summer, it has a well insulated cab but never had ac, for $3500 i can put a/c in it but i dont plan on keeping it after this season, so Im gonna build a cooler like yours and hope i can have cold air all day, keep up the good work and i will get back with you on my findings, gonna use as big a cooler as i can and jugs of frozen water, nothing ventured nothing gained. Again Thanx and keep up the good work.
hi and thanks. make sure to check my latest build on these types of air coolers. it's a 20" box fan conversion using these. big as it gets! if interested... th-cam.com/video/Jfc26AH0jLI/w-d-xo.html
Buy a used diesel generator or a generator motor and add a remote start diesel engine. Frame mount box plates from Rainey's truckparts, Order a esper fuel tank bunk heater pipe for the tank , add filter and buy a windowless ac unit. Minus the ac unit you'll be about 4-$500 in a home made apu. You can get a used apu engine for $1000 but not worth it IMO. Man if you add a 2500-3000w inverter and a trickle charger jump box to your truck you'll be good to go and if any thing breaks you can repair it easily and cheaply with no downtime. I added this to my classic with a Chinese bunk heater 😋👌.
Nice i like it. Do you have any information on the temperature drop of the cooling water in vs out and lenth of time till needing to change ice? Thank you
hi and thanks! temp of water 'in and out' will vary depending on temp of the air in the room and how fast you run the fan. i usually get several hours of runtime before i need to add more ice (varies with amount of ice, used, size of the ice blocks, starting temp. of the room air etc.).
What if those pipes with a small bucket of water you keep in the refrigerator in freezer compartment by making a way to closing the door of it. That's how you can avoid the ice bucket outside even it will help to avoid ice most of the time.
So amazing!! Living in Phoenix I have always wondered if there was a way to use evap cooling without the humidity. Now I know it is possible AND how it is done without making an outrageous electricity bill even worse. Your video is so on point, and the concept and build are understandable to the widest possible audience! Bravo! BTW, how could one make it quieter? Just wondering.....not a deal-breaker; anything that makes the power bill less than the mortgage payment is OK with me. I'm excited to watch your other videos to learn more! Thanks!!!
hi there. these units typically run very smooth and quiet. they just sound like a normal fan running when you are in front of them. the radiator does not increase the sound of the fan. the high speed fan sounds much louder in the video mainly because my camera has dual mics in the very front of the camera - and i didn't adjust the volume accordingly (so what you are hearing is as if your ear is right up to the unit). a second reason is that the high-speed square fan i used has a higher than normal pitch (has a very large motor in it). make sure to listen to how the unit sounds at the end of the video. (just smooth quiet airflow). that is how it will sound to your ear in most cases (with an average/typical fan).
Have you ever done a dog cooling bed? chilled iced water through a tube snaked under the bed floor to keep the dogs cool as they lay down? Or a cooling vest for people to wear the same way?
i've thought a lot about making a cooling vest but am concerned about the condensation issue that some people would encounter. the dog bed idea is good too (but i don't have a pet to 'test it'). i like the idea though and i just thought of a great way to do it (just sitting here as i'm typing). that may be my next video
This is comparative to a chilled water supply air handling unit. I a'm looking to buy the smallest freezer unit and add heat exchanger inside to make chilled water.
So how big of a fan in relation to the radiator? I have a 270 cfm 4 inch inline blower. The radiator is a 7x9 and the water is icy cold but the radiator doesn’t stay cold very long as it heat soaks with the air coming in. I see you have double 120mm fans on one radiator and then 1 fan on another radiator. So my question is if there’s too much airflow would that cause it to heat up the icy air? I might just buy the 2 120mm fans and run that.
hi. nope it's not loud at all. the only noise is just the sound of a fan running (the pump makes almost no sound at all). you can use lots of different fans with a design like this so you can choose an extra quiet fan or one that has a particular sound to it if you like). note that my camera has the dual mics directly under the camera's lens (facing forward) so it often picks up sound louder than it really is.
Thank you so much! I live in a 200 sq ft studio apartment with my main living space being about 100 sq ft. I'm in Seattle so, for the most part, it's not too bad but it's miserable when it's hot because I live on the side of building where the sun is setting practically outside of my window and my apartment turns into Mordor. Anyway, I took a chance and got the materials for this because it b seemed simple enough and didn't require any major tools. I tried the small cooling fans but the ones I got just weren't powerful enough so I switched out for my Honeywell smallish fan. Though it has a bulbous back, it works and provides so much more relief than using a fan without some sort of cooling element behind it. I got one of those Gatorade insulated drink dispensers and have been able to get about 2-3 hours worth of cooler air. Because the tubes are coming out the top, I'm not able to get the top on so tomorrow I think I might try aluminum foil on the top to see if I can prolong the water staying cold. Also put some small microfiber towels under the cooler to catch the condensation drips. So far, so good. Thank you, again, for sharing!!
Love the mini heat exchangers - great idea.
2 things that would help the time run longer: 1) put the ice/water in a thermos (something insulated). You could notch 2 holes in the side lip for passing the tubes. 2) insulate the tubes with neoprene like insulation. With these 2 things you'll be better able to control the area cooled.
wouldnt work hot air goes through the rad therefore will still have the same effect as if in open air
This is absolute genius, it can be easily solar powered and also turned into a heater. I will make me couple of those and spread them around the house. THANK YOU GENIUS
Sounds great!
@@desertsun02 Would you accept some of my ideas for development?
thats a great idea. another thing to do, instead of having the tubing inside the tub with water and ice packs, you could use another radiator and dump that in the tub with the icy water. the metal will get SO cold and act as a further cooling solution so the water will be colder when it hits the radiator with the fans on :)

@@kevc6115 I have come across the same idea, and would you think making it a bigger fridge could supply the whole house?

I am still playing with configuration in ice chest but basic premise is a 3 gallon bucket with lid fastened to floor of ice chest with metal mixing bowl filled with either regular ice + rock salt or dry ice depending on the volume of air to be cooled & size of coils. In the lid I have quick release couplers to attach exterior hoses. One of the holes will be for CO2 exhaust from dry ice which absolutely must be vented if camping or in tight space as it could cause loss of consciousness. The other two ports are for the flex hoses that I insulated myself to connect to coil radiators or booster pump station. I also have a power connector on the bucket lid 24V only that way everything can be disconnected and not have to take shit apart. In the bucket I put 2 micro submersible pumps mounted on sides of bucket that turn on automatically if there is liquid even if the main pump isn’t running so that things don’t freeze by chance. Then I have main pump in the ice chest mounted to bottom of chest. Pump is actually very strong and is electronically variable via a couple ways (will go into in a bit). The big pump has a relay lead to manually shut off, automatic emergency shut down and for thermostat. I modified an old ice chest and rebuilt it into a nice looking rugged device that just has ports on outside that are labeled for various hose connections, power, data, etc. so I won’t go into the radiator/fan thing because that depends on your own situation but the idea i had with the main cooling unit is to have all the brains and guts in one place. I am currently working on having battery bank in the unit so that it can run on a charge being I intend it for camping. I am also figuring out what to do about the CO2 exhaust if there should be a pressure sensor inside the unit and a valve to bleed off any gas. So I used a raspberry pi as onboard computer with wifi and Bluetooth. It has a tiny 3.5 in touch screen that I bought as a all in one case but of course the main interface can be accessed on any browser or Remote Desktop service. The Pi monitors everything but the point of it is to maximize efficiency and to act as a smart thermostat by throttling 12v fan speeds (more electricity is wasted when start and stopping vs constant variable) as well as the big daddy variable main pump (boosters if applicable). There are temp sensors on radiator coils, inside of egress/ingress coolant tubes, in front of fan (air temp) as well as inline flow/pressure sensors and coolant liquid level sensors…I also added several sensors that are round discs of absorbent cotton should they get wet it will shut the entire system down and an alarm goes off and if it is connected to wifi it will alert on your phone because it would be horrible if a leak starts and all of coolant pumps out flooding the tent/house or whatever. Anyways I have had many prototypes going back starting 10 years ago so I don’t have a final product. I have some finished ones to get an idea of design. It sounds like this is an expensive habit but as long as you know where to buy stuff used and where to find free stuff and trash to recycle. I am an engineer so the #1 step is to put pencil to paper and just start writing down ideas and sketching out some design ideas! Start very loose then start drawing out designs on some graph paper then go to computer to do some drafting, 3D modeling mock-ups with exact numbers shapes and lines, etc. it is easy to change the design in digital form and you can get exact measurements before building or buying the first thing. You can design anything when you know what you are doing with the right tools and software and computer science/coding/it skills. Learning AutoCAD (free open source alternative is called LibreCAD) & Google Sketchup Make (free) will start you on a journey of making a lot of money and solving tomorrow’s problem’s!
I am working on modular design style and way of building underground in-hill tiny home off grid 100% self reliant & sustainable mini homestead with all the technology we are already used to, just more efficiently and healthfully! Stay tuned because you will hear of this project in the next decade. There is a whole team of us all over the world volunteering our time to engineer new technologies and community models that will address the human rights crisis seen all over the world.
Food for thought for Short term cooling you could run ammonia nitrate liquefied in your water to supercool
Love your experiments. I can tell you are not married, as no wife would allow the pieces of your previous experiments to be set around (like under your table and beside your bed). They typically ruin fun stuff! LOL
When testing complicated contraptions one must never forget the last test ....(better the first ) : THE WIFE TEST!!
BS I do stuff like this
LOL now, that depends on the wife, my house resembles a workshop, and I'm on a promise to clear the kitchen as I'm using most of the work surfaces with projects! TBH I think she's given up nagging...
I've ordered my parts to make this I've a quiet running fan that I've had in the garage that I got given a couple of years ago and never used it till now .. and I've ordered a coolbox to place the pump and ice into .. my partner just said to me what the fuck are you making now ! Lol 🤣 it's for her Benefit .. and mine
@@markporter45 Ditto on so many levels. I sourced all the parts from Amazon uk.
Might work Great in DRY CLIMATE..... Humidity requires a tray under the coil if dripping. If air velocity is fast enough though and humidity is reasonable, then there will not be enough Resident Time on the coil for moisture to condense out of airflow. Slow down airflow to Dehumidify. Increase airflow to flat out Cool ... there is a balance required for True Air Conditioning effect involving Dehumidification and Cooling. Same principles apply to full blown Central Air.... if insufficient dehumidification is occuring then you need look at Blower Speed setting. BUT BEWARE of EXCESSIVELY LOW SPEED AIRFLOW or Clogged return air filter resulting in similar low airflow condition which will cause Ice to form on Evaporator Coil and lead to System Damage if liquid refrigerant makes it way back to the compressor outside. YEAH... Went on a bit but point was to make comparisons and Educate.

Thank you for sharing your time and these encouraging results. I had this same heater core based idea cross my mind over the past couple of years, after watching a video featuring a cold copper coil zip-tied onto a box fan. I knew we could do more efficiently. You have given me confidence now to actually spend money on my own compact design without worry. I propose a version that has the coolant sealed inside a vessel that can fit fountain pump in the opening, like a half gallon mason jar, or something. I also propose using cheap vodka instead of water. The Russians historically used vodka as a superior coolant in some of their older military aircraft. This way you could drop the vessel into the bucket without needing to worry about priming the system before each use. Thanks again
Instead of using the ice, try using a bent copper pipe placed down a well to use as a heat exchanger to expel the heat into the cold well water.
this dude literally is a genius
I made one of these a few weeks ago using a transmission oil cooler with a thick walled foam cooler. (Like they ship lobsters in) I mounter the fan with the heat exchanger onto the lid and drilled holes for the input and output lines to go into the cooler. I stuck in 4 large ice blocks (Made from freezing water in qt. size potato salad containers) and had my 4w adjustable output pump set to the lowest setting as was my fan and the air off the fan was 54 F. Nice and cold. My problem was, all the ice was gone and the water was room temperature (85 f) after only 45 minutes. My heat exchanger is too efficient I think so I need to restrict the water flow through it. If I could get 68 f air out of it I am sure it would last much longer. I still have more experimenting to do. I am using this in a small bedroom that does not get much of the ac from the heat pump.
hi. options to extend ice and cold water are smaller heat exchanger, slower water flow, smaller pump (big ones can heat the water), and one big way to extend times is to use a speed controller to slow fan even more. the slower the fan the longer the (cold) will last. i got 11 hours once on a 3lb block of ice in a foam cooler. fan was really slow but it was cool enough.
@@desertsun02 Thank you, I will try to limit the water flow and slow my fan down even more. (It is pretty slow on low)
Brother DS02,
Great movie!! I fwd this to a couple ppl and mentioned that, if using the 5 gallon bucket method, a couple one gallon milk jugs, filled 3/4 of the way, or so, would be cheap and easy to rotate from freezer to bucket. Keep up the good work.
hi there. that is a great idea! couple of frozen gallon jugs and 5 gallon bucket might cool for 6 hours or something. btw - thanks for sharing it!
Dan, agree great idea man! I will do just that, thanks
It's an interesting design. Although if you go 9 to 10 feet down in the ground. It's a study 50 to 60° year round. So a simple air pipe technology can augment your heating and cooling greatly.
Great build. The 5 gallon bucket with a lid and grummets to keep all cold air tight for as long and possible. Plus rap the bucket in an insulation. Boom a win win cold all day DC 12v air conditioning. Awesome.
I use 12v cooler, freezer combo for gallon milk jogs, in my van. This will make cold air 24x7.
@@MrLegendfx what is a 12v cooler freezer combo??
@@sharonmetzner1798 I think he's talking about a small 12 volt refrigerator/freezer for small trailers or in his case his van. I've used them, some are propane/12volt/110 combo. freezes his water jugs in it to use in his ac system. the older ones have a small center ice tray size "freezer" that freezes and keeps the unit cold or crank it up and freeze stuff. You could use a separate dedicated solar panel for the freezer, rotate jugs during the day in the AC unit cooling container.
Just an idea. But what if you placed a second radiator submerged in a bucket of salt water with maybe dry ice packs, and the liquid going between the two radiators being a closed system. Then potentially mixing in some antifreeze to the sealed system, depending on how low the temperatures drop.
Great idea ! Thanks, water pump and fan can be 12 volt and solar compatible !
Take one of these out on the boat for a days fishing and drop the tube right in the water, keep ya cool without bothering the fish or using up the ice in your cooler 😁
great use 👍
The paint can is a great idea for the cooling Reservoir. Just needs some way to insulate the paint can and the lines. If you could set the cooler on the top of the can make the hose fitting be all inside the paint can and only have you wires for the fans and pump coming out the lid. Would help make the Ice block last longer inside
Same concept on how a chiller works. Air cool chillers cool the water at 55 degrees. Pumps are used to push the chill water into the evaporator coils. Blower motors push air into the the evaporator coils and cools mega buildings. Return water pumps into a water tower. Nice miniature chiller 😎
This is a great idea for a little spot cooler to blow on you for a few hours or maybe cool a bedroom! But it’s not a good solution for cooling a living space if the freezer you’re using to freeze the ice packs is in that same space. You’re just transferring heat from the air into the water, into the ice pack, then your freezer will transfer the heat from the ice pack right back into the air… and generate more heat in the process.
Great!. Moving out of my home into an RV soon. This will be great. Hate, hate, being hot!
Its really beautiful. Its just that we can not make ice during a solar flare direct hit on earth when the power grid is destroyed.
hi. if power grid was destroyed you'd have to tap natural sources of cold water. (well water, lake water, river water etc.) or use evap cooling technology to cool the water source. you could also tap into the natural coolness a few feet underground (run water through a pipe underground to cool it down... things like that). ...just a few random thoughts
Lol ever heart of solar power. Off grid. In our days very affordable.
There's interest out there for these..I'd stay on it !
hi there. i'm certainly stoked about them. they work fantastic and are easy to build. one more (a giant version i'm building) is in the planning stage at the moment. it's going to be bigger than all 3 of those transmission coolers put together with a 2000+ cfm air output. (for people who want the ultimate air cooler) - stay tuned 👍
@@desertsun02 sounds like Central Air LOL wow
@@desertsun02 Wow!! Have you built this yet??
@Sharon Metzner i built something close. i used two of the larger radiators (model 405) and attached them to a box fan. if interested here's the links...
1.) th-cam.com/video/Jfc26AH0jLI/w-d-xo.html (original box fan conversion video)
2.) th-cam.com/video/oAuL-ScEWfI/w-d-xo.html (extended semi-uncut version)
I’m thinking of trying this in conjunction with a chiller. It’s too bad glycol chillers used in fermentation are so expensive, but hydroponic garden water chillers are a little cheaper. Im trying to build a system to cool three heat sinks and a radiator for air cooling and spot cooling on the heat sinks that get pretty hot.
Oh hey look, an intercooler for a car in your home!
I found a 6,000btu window unit in the trash for free, it works fine and I don't need to run a freezer to freeze ice. Yours would be great if you had an ice cold free flowing deep water well.
get a large terracotta urn, aka "amphora". the seepage through the unglazed ceramic naturally cools the contents to 4C. there are charts around for the actual drop in degrees for every unit of water lost. if you have 200 odd litres of water held at 4C, you arent going to warm it up much with this set up! all about thermal mass too. its not as limited as the swamp cooler is, still works in high humidity. though of course, its better when its dry...
and yeah, enclose those coolers, all the air through the fan AND the fins. the slower the air through the cooler, the more heat sucked out...
I like that concept... you should try to add pool noodle to the inlet and outlet lines for insulation to possibly get even cooler results!
Place the bucket into a planting bag 2" or 3" larger in diameter than the bucket, then put insulation material between the inside of the bag and the bucket. Top the bucket with a round pillow or foam. That way, the ice will last much longer. I may give this a shot, Thanks!
both good ideas! 👍😎
I’ve been thinking of getting a 300-500 gallon heater holding tank. Burry it with a Accessible hatch. Run a inlet hose on the bottom and a outlet hose on top. With a pump to circulate the water throughout the house and use radiators with Fans on them to cool down our home. We also have Solar water heaters for our hot shower water. Install a Bypass to allow the hot water to also run through the same radiators in the winter to heat the house. I’m just a little worried because the hot water gets extremely hot because it’s in stainless tubes covered with glass and it gets extremely hot, maybe a Separate radiator in a isolated area and then ducted into home.
You may not need the ice packs as much if you add some salt to the water and pump the saltwater through the coils.
Forgive my ignorance but why?
You should run the water in the bottom and out the top to avoid bubbles. It seems to work well, anyway. Nicely done!
So adding a pan with a hose for drainage and insulating the can to extend the coolness of the fluid....Shazam!
Also if you have an efficient danfoss-like type rv-equipped fridge (think ICECO, Whynter, Dometic, etc), you can use the freezer section to continually replace the ice packs on your small living space. These fridges use no more than 40 watt/hours, so the whole ACTUAL setup for cooling your small RV/small truck camper/camper topper/minivan/full size van is about 50 watts +/- !!! Use this for your sleeping area at night or during the day your living quarters. Maybe separate the 2 areas using some bubble/foil for maximum cooling effect.
One of the best idea so far....
If you live river or lake side, you can use cool bottom water for cooling too.... or water from well... no need for ice
hi yes, those are both very good ideas.
Project looks fun👍 You could maximize cooling by a makeshift duct between the fan supply and coil. That way 100% of air the fan is pulling would blow across 100% [entire surface area] of the coil.
I would like to have one of these to cool while sleeping. For 8 hours of cooling. Was thinking of running the AC a little higher and assist with one of these. Probably would take about 20 gallons of ice water in an ambient temp of 78 to start with. I hate to go thru the trouble to find out. Also, to cool the patio to at least a bearable temp for the dogs outside. Just to humid I'm afraid in Houston. They abandoned swamp coolers back in the early 70's
hi. evap cooling definitely struggles to work in the humid areas. these coolers aren't evap based though - so they work decent in any humidity level.🙂✔
That’s a very good concept and I commend you you are nothing short of a genius but I see one small problem. Try putting a shroud over that entire heat exchanger with the fenders so this way there’s no wasted energy just try it listen to me and I promise you you’ll get a little bit more colder air channeled through that fan thus wasting no energy and putting out more colder air 😝
I used an ice builder system on my boat cabin. They work great.
awesome!
What's an ice builder system?
@@mohammadbadran642 It circulates water from block ice pumped through a coil with a fan blowing across the coil for cooling.
Have you tried a full 20 inch radiator for the box fan and see if there's enough static pressure to blow through it and if so cool a room?
hi. there are companies that sell 20 by 20 heat exchangers but they are super heavy and expensive ($200+). here is one for $223 badger-pipe.com/products/20x20-water-to-air-heat-exchanger-1-copper-ports?_pos=4&_sid=7c37db64a&_ss=r&variant=29108329425
@@desertsun02 hello, I actually found a car radiator on Amazon for 30 bucks when it was on sale, but didn't really pull the trigger since I wasn't sure if a box fan could even push through it.
@@desertsun02 would a box fan be too powerful??
@Sharon Metzner box fans work. i actually have 2 videos showing how to make a unit using a box fan. works good. here's the links...
1.) th-cam.com/video/Jfc26AH0jLI/w-d-xo.html (original)
2.) th-cam.com/video/oAuL-ScEWfI/w-d-xo.html (extended version)
I was actually on Amazon looking at evaporators, can probably use a Thermose and braided tubing
What if you had a mini freezer with 3 holes drilled at the top one for the pump power cord and the other two for coolant feed and return.
The internal radiator then sits in a shallow or deep bath of chilled anti freeze.
The tubes run out and feed the external radiators that have fans attached.
This way, the coolant lasts significantly longer would it not?
It might actually not last longer because you are not taking advantage of the phase change of water melting. This absorbs lots of heat and keeps the temperature consistent which helps with giving a temporary cooling boost. If the water is cold enough then yes, it might outcompete the just ice version
can this be scaled up, using a used car radiator from a junkyard?
Wonder how well that would work in semi
What are the small fans connected to? Would an AC power supply from an old gadget work as long as it provides enough volts and watts?
Thanks for the great work you do! Once again you've given me a simple solution so I don't have to reinvent the wheel. I wanted a simple heat exchanger for solar heating my greenhouse in the winter and this idea will work perfectly!
Well they the guy should have showed us the adapter used to power the fans they usually 12 volts you probably need 500 mamps or 1 amp to power them
cool idea bro,keepm coming....😃👍
Thanks, will do!
how do we combined the solar ice maker to make this close loop off grid AC!! would be awesome!
That's really easy
I've been watching videos for making these for 2 weeks and this is a great idea using the trans coolers. I am going to use this method and install it into a 50qt. cooler but am researching the best ways to make cold temps that last the longest balancing the radiator size with just the right amount of water flowing through it so my ice/cold water will last longer.
I am currently making one of these using a 48 quart cooler and the same mid sized radiator you used (mine is about 7.5 X 8.75 inch). I cut holes into the top of the lid for the two tubes, so the radiator sits vertical on top and its tubes go directly in/out of the cooler. Almost no tubing is outside of the cooler. The only holes in my cooler are for the two tubes and the pump power chord.
However my fan is also smaller than the radiator like one of your examples (lots of radiator space around the fan not getting airflow). Do you think that is inefficient? Would it be better to enclose the radiator somehow so that it gets a more even air flow through the whole area of the radiator? I am trying to optimize getting the most out of my ice before it melts.
Really enjoying these videos. This was the perfect idea to cool down my room as well as my car for road trips (AC is broken) Plus I love DIY projects like this.
Did you ever finish your AC project? Curious how it turned out. I was thinking about doing something similar.
How long before you need to replace the ice packs
hi. i'm getting one to two hours of cooling just using a gallon of water and 2 ice paks. for extended cooling times (3-6 hours) use more ice or ice paks or even an ice chest. you could double or triple the time that it will cool (even more if you use large blocks of ice). for max. times fill the bucket with water and freeze the whole thing overnight. then when ready to use just add a little water to the top and put the pump in (you might get 8 hours of run time).
Not worth the constant hassle to change ice
develop it or sell it !! so we can have A/C with out copressor . less hummed air and low power !! good job
If you add salt to the water you can reach lower temperatures, 150gr in 500ml
Cool exprement u inspired me to copy your design but ill upgrade it by putting the water bucket in a mini frige run by a compressor just got to drill two holes for the pipes and thats it hopefully it be as good as any ac
hi. sounds like a good plan! i'm currently working on another similar unit. it will be out in maybe a week. it basically has a fancier "removeable radiator" stand (combined with a mini "table top" shop fan). it will be the fastest and coolest one so far.
@desertsun02 oh cool can't wait to see what you make your videos often inspire some of my most fun projects :)
To make this even more efficient; in my mind anyways, and for a larger scale use. Sink a holding tank of some sort; IBC, plastic drum etcetera, in the ground; well below grade, and cover it up. Of course you'd have to install the proper plumbing before hand. Run all that into a manifold where you could split off to individual lines for separate applications. Insulate all your above ground lines. And you could; in theory, always have sub 60° water for circulation. Right? Yup! In my mind anyways. That way you remove the need for refrigeration and ice.
And with black poly vinal tubing you could go solar for heat as well. Coil up a length of poly vinal in a glass covered box and you'd; in theory, create a hot water radiant heat system.
You've got my brain going now, Sir! I'm glad I found your channel again. I misplaced it for sometime but now I'm back. I'm glad you're still making videos.
hi there. good ideas. i've always thought the idea of going sub-surface for cooling is an excellent idea. if your water is even 60F you get some awesome cooling out of these devices. (i even ran plain tap water (72F) through this device and got a 5 degree temp drop with no ice or cold water at all). the solar option for heating the water (to make an air heater) is great idea too. just circulate every so often and you've got almost free heat. btw i'm glad you found my channel again! i'll hopefully be making videos for 20 more years
You can put one cell or two cells of the peltier in the aluminum container and it will improve but the heat generated must come out
I remember these ACs back when the ACs were barely coming out.🤣🤣🤣😂 I'd find them in old shops as a kid.
Would this compact version cool down a small living room a few degrees or is it just for spot cooling? Thanks for the video
hi. it would depend on how hot the room is, how big it is, does it get lots of sun and all of that but unofficially, i've seen temp drops in a 10x18 room (my living room) by 5 degrees (83F to 78F). the best i can tell you is it seems to cool half my living room pretty well (so maybe 2 units would do it?) or one for a smaller 10x10 room.
But making the ice would heat the house more than this cools overall. So it just moves heat arround your house. But overall it heats your house.

Have you ever thought about taking a refridgerator or a deep freezer and removing the doors and sticking a large box fan in front of it to see how long it would take to cool down a room such as a garage or a kitchen etc
Have you thought where the heat from inside the fridge/freezer goes? You would have to put the fridge/freezer outside and then duct air into the room
@@richgoodman5734 no I have not Im new to this

You should try with a high percentage alcohol and a use a freezer to get it even colder
How about compressor free absorption type refrigerator and air-conditioning using induction as heat source, they are starting to discontinue 3 way refrigerator in RVs ?
I made one the radiator drips a large amount of condensation. Other than that seems to work well in my 6 x 12 trailer.
hi there. yes that happens with high humidity. units typically still work well though (plus the condensate is water being removed from the air - so that should help the air feel better too)
I'm thinking.use your trans cooler as in this video. If you have a 12vdc travel refrig freezer.put your cooling lines through the horizontal hatch cover with a type heat exchanger in the cooler.
How much water do you put in the bucket to supply your chill lines?
Any ideas.

Been following your progressin on these units, like your work, i have most everything i need to build one, but for me its a must instead of a project i have an older peterbilt truck that i have to drive this summer, it has a well insulated cab but never had ac, for $3500 i can put a/c in it but i dont plan on keeping it after this season, so Im gonna build a cooler like yours and hope i can have cold air all day, keep up the good work and i will get back with you on my findings, gonna use as big a cooler as i can and jugs of frozen water, nothing ventured nothing gained.

Buy a used diesel generator or a generator motor and add a remote start diesel engine. Frame mount box plates from Rainey's truckparts, Order a esper fuel tank bunk heater pipe for the tank , add filter and buy a windowless ac unit. Minus the ac unit you'll be about 4-$500 in a home made apu. You can get a used apu engine for $1000 but not worth it IMO. Man if you add a 2500-3000w inverter and a trickle charger jump box to your truck you'll be good to go and if any thing breaks you can repair it easily and cheaply with no downtime. I added this to my classic with a Chinese bunk heater 😋👌.
Nice i like it.
Do you have any information on the temperature drop of the cooling water in vs out and lenth of time till needing to change ice?
Thank you
hi and thanks! temp of water 'in and out' will vary depending on temp of the air in the room and how fast you run the fan. i usually get several hours of runtime before i need to add more ice (varies with amount of ice, used, size of the ice blocks, starting temp. of the room air etc.).
Pretty cool..u should enclose it in a box so the air is forced over the entire heat exchanger..
What if those pipes with a small bucket of water you keep in the refrigerator in freezer compartment by making a way to closing the door of it. That's how you can avoid the ice bucket outside even it will help to avoid ice most of the time.
i've been thinking of trying something similar
@@desertsun02is a great must try then i will wait for your video
So amazing!! Living in Phoenix I have always wondered if there was a way to use evap cooling without the humidity. Now I know it is possible AND how it is done without making an outrageous electricity bill even worse. Your video is so on point, and the concept and build are understandable to the widest possible audience! Bravo! BTW, how could one make it quieter? Just wondering.....not a deal-breaker; anything that makes the power bill less than the mortgage payment is OK with me. I'm excited to watch your other videos to learn more! Thanks!!!
hi there. these units typically run very smooth and quiet. they just sound like a normal fan running when you are in front of them. the radiator does not increase the sound of the fan. the high speed fan sounds much louder in the video mainly because my camera has dual mics in the very front of the camera - and i didn't adjust the volume accordingly (so what you are hearing is as if your ear is right up to the unit). a second reason is that the high-speed square fan i used has a higher than normal pitch (has a very large motor in it). make sure to listen to how the unit sounds at the end of the video. (just smooth quiet airflow). that is how it will sound to your ear in most cases (with an average/typical fan).
as far as I understand this doesn't use evap cooling but it's still cool
Bruh you live in Arizona desert, GET A SWAMP COOLER. People in Floridas wet climate wish they could use a swamp cooler.
@@whydontyouaskme I agree. Arizona has low humidity, dry air usually during the summer.
Have you ever done a dog cooling bed? chilled iced water through a tube snaked under the bed floor to keep the dogs cool as they lay down? Or a cooling vest for people to wear the same way?
i've thought a lot about making a cooling vest but am concerned about the condensation issue that some people would encounter. the dog bed idea is good too (but i don't have a pet to 'test it'). i like the idea though and i just thought of a great way to do it (just sitting here as i'm typing). that may be my next video
This is comparative to a chilled water supply air handling unit. I a'm looking to buy the smallest freezer unit and add heat exchanger inside to make chilled water.
hi. yes, indeed. sounds like a good idea! i've got a mini freezer (but so far i've held off on drilling holes into it) (for the tubing).
would a Peltier running on solar work to cool the water enough to make this last longer than 2 hours?
what if you could use car a/c recharge for the refrigerant?
So how big of a fan in relation to the radiator? I have a 270 cfm 4 inch inline blower. The radiator is a 7x9 and the water is icy cold but the radiator doesn’t stay cold very long as it heat soaks with the air coming in. I see you have double 120mm fans on one radiator and then 1 fan on another radiator. So my question is if there’s too much airflow would that cause it to heat up the icy air? I might just buy the 2 120mm fans and run that.
What would be the advantage of having a faster pump?
Great idea. Sounds loud. Is it?
hi. nope it's not loud at all. the only noise is just the sound of a fan running (the pump makes almost no sound at all). you can use lots of different fans with a design like this so you can choose an extra quiet fan or one that has a particular sound to it if you like). note that my camera has the dual mics directly under the camera's lens (facing forward) so it often picks up sound louder than it really is.
@@desertsun02 Thx! Good to know. I was thinking it might have been the mic. Brilliant idea.
Why is air conditioner in air ice water compass fan cool!
Cool Video
Insulate the bucket so it lasts longer,, put ice and salt in the bucket to bring the temperature lower
what if you try to use a paitel cel ?
That would work great with some dry ice and refrigerant or coolant
is car evaporator will work better instead of that?
Excellent. Thanks for making and sharing this video.
hi. you bet! - thanks for watching and commenting 👍🙂
A 12 volt system would be perfect for rv living if it didnt have AC already👍
hi there. yep, i love the 12v. great for emergencies, power out, camping, tailgating
That's what I'm using it for. I live in 6 x 12 cargo trailer conversion this unit is working well.
how about puting dry ice in water or a container then into water
Do one with a 45" drum fan!!
is a good idea
Fantastic! Thanks for sharing your invention would like to try to build one of these myself.
hi. you're welcome 👍. i say go for it 🙂
Thank you so much! I live in a 200 sq ft studio apartment with my main living space being about 100 sq ft. I'm in Seattle so, for the most part, it's not too bad but it's miserable when it's hot because I live on the side of building where the sun is setting practically outside of my window and my apartment turns into Mordor.
Anyway, I took a chance and got the materials for this because it b seemed simple enough and didn't require any major tools. I tried the small cooling fans but the ones I got just weren't powerful enough so I switched out for my Honeywell smallish fan. Though it has a bulbous back, it works and provides so much more relief than using a fan without some sort of cooling element behind it. I got one of those Gatorade insulated drink dispensers and have been able to get about 2-3 hours worth of cooler air. Because the tubes are coming out the top, I'm not able to get the top on so tomorrow I think I might try aluminum foil on the top to see if I can prolong the water staying cold. Also put some small microfiber towels under the cooler to catch the condensation drips. So far, so good. Thank you, again, for sharing!!
