It took little me less than an hour to make, thanks to your clear video and our abandoned fish tank. I put the cooler on the lower shelf of our old rolling TV stand with the fan on top. I had great fun watching my husband’s face trying to figure out why our room was cooler when he returned. He was amazed. The most fun we had for a long while. As you said, go slow on the ice and it will last a while. We have a deep freezer ;oD - maybe we sell ice to the neighbors - thanks for sharing.
Best to put a one way water inlet, prime the system with water in the copper tubes. Then fill ice chest with ice to cool the tubes. With no running water on the ice and a continuous flow of cold water in the copper tubes it will stay cold much longer and be more efficient in cooling. Awesome video though 👍
I have made these before and they really do work. I have a couple of suggestions. First, the biggest mistake people make is getting a really small submersible pump. Go ahead and spend the little extra money and get a good 150-200 gph pump. The little ones will not circulate cold water fast enough to keep the tubing cold all the way around the fan. The tubing will start to warm up about half way through. Plus, the small ones will only lift water about 2-3 feet vertically. Second, if you have enough copper tubing go ahead and use it for the coils inside the cooler. Plastic will work up to a point, but the copper tubing works a lot better. Good job on the design and presentation!
IT WORKS EVEN BETTER WHEN YOU COIL THE COPPER TUBING A VORTEX SHAPE BASE CONTACT ON FAN TO THE EDGE, THEN COIL IT TIGHT WITH A 3" HOLE AT THE END.. IT WILL COME OUT 15 COOLER.. I GOT THE IDEA FROM INDIA WHEN I WENT INTO SHANTY HOMES PEOPLE THERE WERE USING SODA BOTTLES LIKE YOU SEE ON YOU TUBE.. IT WORKS WITH OUT ENERGY AND COOLED THEIR LITTLE METAL HUTS BY 23 DEGREES.. IMAGINE WHAT YOU CAN DO WITH A USED SOLAR PANEL, COPPER TUBING IN VORTEX SHAPE, SALT WATER IN OLD SODA BOTTLES AND OF COURSE WATER AND WATER PUMP AND TUBING.. REMEMBER TO USE A INSULATED ICE BOX.. 3 TO 4 HOURS OF NICE.....AC
brilliant channel for DIY and inventive projects. your solar tracker remains my all time favorite! well done, truly generous free sharing channel. keep it up.
Planning to make one but it ain't gonna be easy because I live on a ship which in the high season will be sailing with guest. I will have to account for rolling, yawing and pitching to make it work in all conditions. I will be using the material I prefer to work with anyways which will make it more complicated but at the same time about as good as undestroyable. I have found a very good watertight cheap construction method over here where I live. I can get foam sheets of 2000x2000x3 mm 10 in a pack for only 6 euro and which are very durable if impregnated with a very thin layer of epoxy. Sheets can also be laminated together using a thin layer of epoxy. They can be molded in almost any form as long as you are carefull not to overstress the material. Greasing lines before making the fold are sometimes a very good method to overcome this problem. Also using simple sheet paper laminated on both sides seems to do wonders.
Put a cryogenic Stirling cooler in it and use miltitherm to circulate the fluid through the copper coil. Put a wrot counter sink in a bucket of water on the return flow to bleed off the heat before the next cycle.
It should cool a room of this size if not in direct sunlight, especially if external temperature is around 30 degrees Celsius or less. But it would still be a great relief for higher temperatures producing a very cool breeze for about 3 to 4 hours. Follow the instructions of using large ice bottles containing frozen salty water and have backup ice containers. Also make sure you leave enough space between the copper coil tubes on the fan screen... It is worth trying. Good luck.
I'm using an Ice Chest, a "Blower Motor/ Heater Core assembly" out of a GMC astrovan, and a 12 volt Bilge pump. Works pretty good. just had some problems with the Power connection for it to plug into my car. lol!
We tried the bilge pump, but our water output was too high. The aquarium pump was perfect, and raising the fan by a few inches reduced the cold water flow if necessary.
You should get 3 to 6 hours of cool air depending on the initial temperature of the ice water and the room temperature. To maximize efficiency freeze salt water in large bottles to cool the circulation water and refreeze the salt water bottles for later use. Also keep spare salt water bottles for continuity. Basically, all such devices give you a cooling relief better than a fan and usually you sit within the airflow. It is not an air conditioner using compressed gas at 1500+ Watts. It is best used for a person with low tolerance to a heat wave, especially older people. Use 2 devices if you like but you need to make double the ice. Some places sell ice blocks that you can break into large chunks and use in the cooler.
Ok say i make a kids carboard home/play area and its too hot will this work inside its not so big its crawling level but the length and width is almost same as small rooms.
This fan works like a small air conditioner and as it is shown in the video, can cool a small closed room for a few hours. I wouldn't keep it too close to where children might be playing, but if you put it on a table away from movement, then it should cool the whole room. If you are not technically inclined to make a sturdy device, then better invest in a small air conditioner.
It is best to get a submersible aquarium pump. You may have choices of pump power, so select a medium power for a small aquarium the size of your cooler. If you place your cooler with your pump much lower than the level of the fan, then a weak pump would slow the flow or just push a column of water to a certain height without circulating the water... in short, choose the more powerful pump for the size of your cooler.
@@shippolee1811 Good question! The short answer is: No, it does not. It may lower the room temperature by a couple of degrees provided no external heat source is coming in (like the Sun heating the roof or walls, or through the glass, and no warm air coming in. This device is intended as a cooling fan that you have to be sitting around. You can fix the fan with loose tubing so it can rotate and cool a group of people sitting in the direct cool air stream - ideal for older people and those who cannot tolerate the heat. The Physics of this is that your system is coolest when it starts and gets warmer as it exchanges heat with the air in the room. Compared to an Air Conditioner that provides cool air at 17 degrees continuously since its cooling is running on continuous power. Still, it is a good device as long as everyone understands the limitations and work it according to the guidelines in the video.
can someone comment about the moisture/precipitation and created-humidity for something like this... from what i know it would seem that this system doesn't have that issue... is this true? since it's enclosed... BUT how much precipitation do the copper tubes give off? thanks for any responses!!!
HI! Q: I'm thinking on doing this project using a 24 inch industrial pedestal fan... do you think I should increase the copper tubing diameter? Best regards!
Pretty much its what you see in the video. you can buy the tubing at an air conditioning shop or hardware store. the pump you can get at a fish shop. get one for a tank the size of your cooler and if the salesperson gives you an option for the pump get the larger pump. The pump output would be greatly affected by its height above the cooler water level, so keep it on top of the cooler and keep the fan close in height as we have done. Good luck...
No such device can cool an entire room at high temperatures. For that you need an electrical air conditioner of appropriate capacity to the cooled room volume (room totally closed from external heat and fairly insulated). The A/C requires significant continuous power to overcome the heat exchange of the air temperature of the room (including material stored heat and people temperatures). This device is useful up to temperatures of around 30C, over that it can only provide cooling relief to people in the range of the cool air flow.
@@nielmarvicgarces8726 the smaller the better.... depends on your room temperature.... you can use more or larger fans, but with high summer heatwave you need a lot of ice.... try it and find out according to your place....
alum. is the best for an a/c unit . when the heat exchange unit is enclosed in a cooler it will cool the water much faster.copper will be better when you are just using a fan...
okay science club I have a question..... instead of using a cooler as a remote source for cold water... can I run the copper tubing into my refrigerator and us a gallon jug of water as my reservoir and have things circulate that way? also what is the flow rate of the aquarium pump that you're using on there and what size aquarium pump or water pump would I need for half inch tubing. I am looking to cool off a 2 car garage.
Rob S. I know this is an old comment but I had the same though for the same situation, let me know if you tried it and if it works, but if you still want it colder use your freezer instead just add a lot of salt to the water then it will be unfreeze able
Nadeem baig + The cooling duration would depend on the size and starting temperature of your room and the quantity of ice in your cooler. For the model in the video the cooling was effective for about 5 hours before more ice was added. Keep the space you want to cool fairly closed and keep spare ice bottles.
Science Club - Kids and Parents can I know more details about ur project..such like diameter copper and PVC..or power of submission...flows of water and how ur conclude this experiment...because I want to try doing this

If you refine your setup to be efficient, it will work like a 1-Ton capacity window AC as long as you add ice every 5 to 6 hours - here, large bottles of frozen water work best at lasting longer, while a cocktail ice bag would work faster at cooling the water in your cooler. The remaining issue is how well-insulated your room is. Even with a great air conditioner, if the heat coming through a window or from the walls and roof of the room is great, then the heat will overcome the cold - something like operating an AC next to your oven. Ideally, your room should be well shaded during the day sun, curtains closed to avoid the greenhouse effect, and when you operate the AC, the room should be almost sealed from outside hot air. Many people use this AC project fan with windows open, but this will only give localized cooling and does not build up into cooling the whole space. In conclusion, if this setup does not work in your room of about 16 square meters (170 sq feet), then you have a significant heat gain you have to resolve.
You can use any kind of tubing to cool the air produced by the fan. You can continue with the same plastic tubing if you like, but copper tubing is rigid and will stay in place better and would have better heat exchange properties than other materials....
Depending on your room size and if you can keep the hot air from coming into your room and close your drapes from direct sunlight, around 5 to 8 hours or more. keep two sets of frozen bottles, one in your cooler and the other in your freezer and add ice bottles to your cooler as you need it. Keep your cooler lid closed tight of course.
It will eventually work if you manage to close the room to isolate it well from outside air. The condensation will become less since the humidity in the air of the room will be condensed and drips back into your cooler. Only outside air will bring back humidity.
Teaching kids how to waste electricity? This project is cooling one room by using the freezer of a refrigerator or freezer in another to make ice, (which will be venting more hot air); thus, you're using a lot of electricity and added equipment, rather than get, (or build), a room-sized air conditioner.
Plus cooler, plus electric fan, plus copper tubing, plus PVC tubing, plus aquarium pump: adds up! And, freezing water bottles still produces more vented heat, (where the freezer is located); and, even a cooler filled with frozen water bottles may not last more than a few hours. Adding salt to the freezing water bottles really doesn't provide cooler temperatures than ordinary frozen water. And, why use an insulated cooler, when the idea is to cool a room with the cold water? Worried about a little bit of condensation? Instead of all this equipment, use a "zeer pot" to cool some water. Two clay pots, sand, and a fan, (optional). th-cam.com/video/LOrNVvbGcQU/w-d-xo.html
Yeah, agreed, but the idea would be a heat relief during a heat wave where people do not wish to buy, or cannot afford and AC unit, so they can improve the performance of their fan. We tried evaporation coolers, and they were slow unless you put wet fabric in a cooling tower as was done in the Middle East, especially old Dubai.
Both ways work. Behind the fan might work better if you have a fairly enclosed ducted flow like a wind tunnel effect. Of course you might be thinking like a car radiator fan. for us, it was easier to take the front grill off the fan to attach the tube coil, and it works close enough....
From our experiment, the same unit you see in the video ran for some 3 hours during a science fair with high humidity and produced considerable condensation. In a small closed room, it would remove the humidity after a while. In open air, you would have to stand in front of it, as with any AC unit. If you try it, please share your results.
not sure what you're doing to get such poor results. Today 19 May, we used the same setup using 2kg bag of ice and 3 of 500ml frozen water bottles that lasted over 4 hours outside in an open air science fair. Ambient temperature was 28 degrees C, humidity 60-70%. condensation was very high on the copper coil - we were literally making water. You might want to try a better insulated cool box, and use larger frozen water bottles, and/or run the fan/pump at slower speed. Good luck.
i already tried this and it doesn't work. don't believe on this thing although there are lot of videos about this system. don't waste your time doing this..
you have to balance the flow of cold water with the speed of the fan. you can raise the pump (the cooler) or lower the fan.also, don't put too much water in the beginning as it will melt the ice too quickly. the first time you have to use more ice to lower the temperature of the water.you have to insulate the room from outside heat by closing windows and curtains. depending on how hot it is where you are, you have to keep large bottles of frozen ice on hand. good luck. read below some fans of the idea.
just play a video of you doing this... jeezus if I wanted written instructions I could have just went to a website to read, TH-cam is for video instructions, you claim it's easy then put THAT in your video!!!
okay science club I have a question..... instead of using a cooler as a remote source for cold water... can I run the copper tubing into my refrigerator and us a gallon jug of water as my reservoir and have things circulate that way? also what is the flow rate of the aquarium pump that you're using on there and what size aquarium pump or water pump would I need for half inch tubing. I am looking to cool off a 2 car garage.
Interesting concept, but it wouldn't be efficient since the fridge compressor is designed to cool a well-insulated fridge box at a slower power rate than an AC compressor. Besides, at full operation, a fridge consumes some 100 to 300 Watts, whereas an AC unit requires 1000 to 1500 watts - hence the efficiency (but somewhat ice inconvenience) of our device. The power consumption of the refrigerator and the Air Conditioner depend largely on the time their gas compressors keep running. The fridge operates at 25-30% of the time and the AC unit at almost 80% depending on cooling setting. So your idea might work except your fridge would continuously work to cool the external water reservoir and may not work well to cool your food. We used the "Astro AS 1000" pump with rated maximum discharge of 1000 liters per hour (265 USG) to pump up to 70 cm height (the height of the fan coil tubes from the pump) so the actual discharge was about 500 L/hr as per the pump chart. No worries, slow is good. For a 2-car garage you would need a 2-ton AC unit. But don’t give up on the idea in this video yet. Try building one unit, it may as well be enough if you have your garage fairly insulated and draft free from outside hot air. Otherwise you can make another device if convenient to you. The disadvantage would be keeping a stock of ice bottles or hopping to the supermarket for bags of ice that you may store in your freezer or spare coolers. All the best and stay cool this summer….
I don't get it. if he puts a water jug with the plastic tubes inside the fridge and somehow connect the tubes to the outside copper tubes on the fan, that should work, right? theoretically at least, since you have to be near the fridge all the time.
+Kal EL ....... thank you for seeing my idea the way I was explaining it ( also I'm sorry for not giving all the details of the setup ) ... some times it's hard for some people to grasp the mechanical nature behind a description. but yes the fountain/aquarium pump would being in the fridge in the Jug to pump the water through the lines. I would have to drill 2 holes in the side of the fridge to attach the lines to the coil( the holes would be a really snug fit to the lines). instead of copper tubing and the cost that goes with it, I would probably get a transmission cooler from an automotive parts store and circulate the water through there with a fan blowing through it. I believe them transmission coolers are aluminum so heat transfer or cooling transfer would be greater than copper. give this concept and idea or a trial run science club and let me know what you find out. if anybody else out there has a better idea on the same concept let me know. it's all worth a try and it will always be trial and error.
The principle would certainly work if you cool the circulating water with either ice water or in a container inside a fridge. The method would have to be tested to check the efficiency of cooling and of course would depend on the cooling capacity of your fridge and the temperature of the room you want to cool. The question would then be whether cooling the air would work continuously or fade away as the fan warms up the water returning to the container faster than the fridge can cool it.

you could do the same with 2 large transmission coolers and rv water pump and small radiator fan to make portable for camping

Q: I'm thinking on doing this project using a 24 inch industrial pedestal fan... do you think I should increase the copper tubing diameter?

Actually, it drips. Also, once the room is cool enough, you can set the fan to lower speed.
how long cooling works ?

one question can I use salt to increase life of ice in that bottles??
absolutely. it may take longer to freeze, but will work, but keep your bottle lids tight so salt will not leak into the circulating water. see 4:28
If salt leak into the water, could it create a problem?
Amita Jain ... in the long run, the salt may build up in your pump and circulation tubes. not a big deal but better to avoid.

Hi.how many hours stay cool..to my room...
Depending on your room size and if you can keep the hot air from coming into your room and close your drapes from direct sunlight, around 5 to 8 hours or more. keep two sets of frozen bottles, one in your cooler and the other in your freezer and add ice bottles to your cooler as you need it.

Resologist -- the idea is that you already have a freezer that can freeze some water bottles at little additional cost.....
Plus cooler, plus electric fan, plus copper tubing, plus PVC tubing, plus aquarium pump: adds up! And, freezing water bottles still produces more vented heat, (where the freezer is located); and, even a cooler filled with frozen water bottles may not last more than a few hours. Adding salt to the freezing water bottles really doesn't provide cooler temperatures than ordinary frozen water. And, why use an insulated cooler, when the idea is to cool a room with the cold water? Worried about a little bit of condensation? Instead of all this equipment, use a "zeer pot" to cool some water. Two clay pots, sand, and a fan, (optional).

Yeah, agreed, but the idea would be a heat relief during a heat wave where people do not wish to buy, or cannot afford and AC unit, so they can improve the performance of their fan. We tried evaporation coolers, and they were slow unless you put wet fabric in a cooling tower as was done in the Middle East, especially old Dubai.
good
There was no need to coil the plastic tubing as water is directly getting dumped in the tub.
Great job: Stupid back ground music . Had to jump off a bridge for a while . {• •}
…. Ahahahahaha
We are DEVO. (- -)
why not narrate the video
AGAIN JEEEZZZ COIIL SITS BEHIND THE FAN NOT IN FRONT OF IT.
Both ways work. Behind the fan might work better if you have a fairly enclosed ducted flow like a wind tunnel effect. Of course you might be thinking like a car radiator fan. for us, it was easier to take the front grill off the fan to attach the tube coil, and it works close enough....
look what u can do with powerpoint!!!
bujhi nai hela je /😆
Ok, I rather go to craigslist and get a air conditioner for 30 bucks.
Not effective in humid weather conditions
From our experiment, the same unit you see in the video ran for some 3 hours during a science fair with high humidity and produced considerable condensation. In a small closed room, it would remove the humidity after a while. In open air, you would have to stand in front of it, as with any AC unit. If you try it, please share your results.
if I don't have ice then it is useless
manna dey if u aren't having ice even then u might be lacking in fan too. Go get some money then !
I don't understand ur technology
ice melts in just 45 mins
not sure what you're doing to get such poor results. Today 19 May, we used the same setup using 2kg bag of ice and 3 of 500ml frozen water bottles that lasted over 4 hours outside in an open air science fair. Ambient temperature was 28 degrees C, humidity 60-70%. condensation was very high on the copper coil - we were literally making water. You might want to try a better insulated cool box, and use larger frozen water bottles, and/or run the fan/pump at slower speed. Good luck.
Drink it
i already tried this and it doesn't work. don't believe on this thing although there are lot of videos about this system. don't waste your time doing this..
you have to balance the flow of cold water with the speed of the fan. you can raise the pump (the cooler) or lower the fan.also, don't put too much water in the beginning as it will melt the ice too quickly. the first time you have to use more ice to lower the temperature of the water.you have to insulate the room from outside heat by closing windows and curtains. depending on how hot it is where you are, you have to keep large bottles of frozen ice on hand. good luck. read below some fans of the idea.

Same video over and over😬
just play a video of you doing this... jeezus if I wanted written instructions I could have just went to a website to read, TH-cam is for video instructions, you claim it's easy then put THAT in your video!!!
okay science club I have a question..... instead of using a cooler as a remote source for cold water... can I run the copper tubing into my refrigerator and us a gallon jug of water as my reservoir and have things circulate that way? also what is the flow rate of the aquarium pump that you're using on there and what size aquarium pump or water pump would I need for half inch tubing. I am looking to cool off a 2 car garage.
Interesting concept, but it wouldn't be efficient since the fridge compressor is designed to cool a well-insulated fridge box at a slower power rate than an AC compressor. Besides, at full operation, a fridge consumes some 100 to 300 Watts, whereas an AC unit requires 1000 to 1500 watts - hence the efficiency (but somewhat ice inconvenience) of our device.
The power consumption of the refrigerator and the Air Conditioner depend largely on the time their gas compressors keep running. The fridge operates at 25-30% of the time and the AC unit at almost 80% depending on cooling setting. So your idea might work except your fridge would continuously work to cool the external water reservoir and may not work well to cool your food.
We used the "Astro AS 1000" pump with rated maximum discharge of 1000 liters per hour (265 USG) to pump up to 70 cm height (the height of the fan coil tubes from the pump) so the actual discharge was about 500 L/hr as per the pump chart. No worries, slow is good.
For a 2-car garage you would need a 2-ton AC unit. But don’t give up on the idea in this video yet. Try building one unit, it may as well be enough if you have your garage fairly insulated and draft free from outside hot air. Otherwise you can make
another device if convenient to you.
The disadvantage would be keeping a stock of ice bottles or hopping to the supermarket for bags of ice that you may store in your freezer or spare coolers.
All the best and stay cool this summer….
+Science Club - Kids and Parents .... okay thanks for the info I will keep thinking about my idea and other ways it might work.
I don't get it. if he puts a water jug with the plastic tubes inside the fridge and somehow connect the tubes to the outside copper tubes on the fan, that should work, right? theoretically at least, since you have to be near the fridge all the time.
+Kal EL ....... thank you for seeing my idea the way I was explaining it ( also I'm sorry for not giving all the details of the setup ) ... some times it's hard for some people to grasp the mechanical nature behind a description. but yes the fountain/aquarium pump would being in the fridge in the Jug to pump the water through the lines. I would have to drill 2 holes in the side of the fridge to attach the lines to the coil( the holes would be a really snug fit to the lines). instead of copper tubing and the cost that goes with it, I would probably get a transmission cooler from an automotive parts store and circulate the water through there with a fan blowing through it. I believe them transmission coolers are aluminum so heat transfer or cooling transfer would be greater than copper. give this concept and idea or a trial run science club and let me know what you find out. if anybody else out there has a better idea on the same concept let me know. it's all worth a try and it will always be trial and error.
The principle would certainly work if you cool the circulating water with either ice water or in a container inside a fridge. The method would have to be tested to check the efficiency of cooling and of course would depend on the cooling capacity of your fridge and the temperature of the room you want to cool. The question would then be whether cooling the air would work continuously or fade away as the fan warms up the water returning to the container faster than the fridge can cool it.
