DIY Air Cooler! Homemade Air Cooler with AC "like" feel! (extended *semi-uncut version) Box Fan conv 

hi. and thanks! 👍🙂

thanks. will do! and thanks for being a long time subscriber 👈👍🙂

@@desertsun02 how long it stays cold pls in hot days?

You will also have 2 pumps generating heat in your reservoir rather than 1. so it's 6 of 1, half a dozen of the other.

hi and thanks 👍🙂✔

you bet.👍 ...and thanks for watching!

Right on!

@@desertsun02 came in works great.

@Dr. ProjectX awesome!

​​@@dr.projectx5142 How long did the ice last? And what about the condensate dropping off of it?

hi. i've read about that type of refrigeration but don't know too much about it.

hi. that's great to hear. i'm glad you like it. ✔😎

Wow, thanks

hey there! i'm glad my videos are helping you! i'm also glad you're making the projects. since the "copper coil" unit is just copper with no fins, the heat transfer is only partial. these fans with aluminum radiators are much better at the heat transfer (and therefore cool the air much better). i'm glad you noticed my other videos on how to use these 'fans with radiators" along with my DIY evap 'water chillers'. that makes indirect evap cooling and is a great way to make the cold water without using ice. for anyone interested in evap water chillers and indirect evap cooling here is my main video on the topic ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I6u6yCe8RzI.html

@@desertsun02 by the way. It works great! I connected the box fan with the radiator on the back and connected it to the evap cooler. Just awesome! Thank you. I want to make a smaller one for my sons room.

thanks!

hi and thanks! i like the hayden transmission coolers the best - but i'm sure there are other good brands out there. i've got videos on running these off of 12v solar panels. to find them fast check the playlist area of channel 👍

hi. the plastic side panels are just on the edges of the fan. they end right at the edge of the radiators so they don't block the airflow between the fan and the fins.

How long did it last for you? And what about water dropping from the transmission oil cooler? How did you deal with that?

@@007alztruli so since my ice would melt pretty fast I started to use bags of ice with ice packs included to keep the water colder longer. I also put foam insulation on my hoses. It was a piece of foam that looks like pool noodle but made for pipes to insulate them. Instead of a homedepot pocket I used a actual ice chest too. And I would also get a lot of condensation on my transmission cooler so I would put like a towel underneath my fan to catch the water dripping that was caused my the condensation. Another thing that would would help was spraying the coils before hand with cold water to speed up the cooling process. Hope this helps.

​@@Guzman3605Thanks. You didn't say how long the ice lasted though...

hi and thanks. yes, they sure do.

yw 🙂

hi there. i hadn't thought of that but that is a great idea. if they can cool the water at a good pace that might be the answer to cooling 24/7 with ease.

A cheaper option might be putting the pump and water in a "portable mini fridge cooler" and drilling some holes through it for the tubing. They are about $44. Not sure how much power they draw.

Right on I was thinking of using a small refrigerator put the fan on top the hell with that ice water and sweating bucket you just keep your bucket in the refrigerator and run the hoses up

@@bigzen69 the problem is the water is being cooled... as the fridge emits energy into the room🤣

@@matthewhodes1908 exactly you would need to dump the air to the out side from what ever is cooling the water. I would use something like this out on my sun room that doesn't have ac to it. I could work in cool space and then just refill the warm water.

You must have missed his reply in the other video. Here it is. hi there. very important - don't just zip tie it to the fan. it will wreck the heat exchanger (it will bend the fins making it unusable *among other things). the styrofoam is for several things. 1.) it's for protecting the fins. 2.) for offsetting the radiator from the fan to handle the condensation. 3.) to stabilize the fins onto the fan so the unit won't shake or move around.. 4.) also it absorbs any noise. it's like a firm cushion between the fan and the fins. 4.) keeps the whole thing running smooth and quiet.

thanks very much 👈👍

he has a few he made with copper tubing and one with copper tubing and aluminum fins but you could also just use a garden hose, it wouldnt be as efficient but it would still be cold from the water and theres no reason you couldnt recycle an old window ac's radiator system or look through a salvage yard for one

its cooling the room faster thay way, where do you think the cold goes when it escapes the bucket?

@@shockat5070its NOT going to cool the room down, its only for spot cooling.

Y'all want him to come to your house and build it for you or can you put the obvious ideas of your own into the build?? SMH......😒🤨🤔😎👍.

Indeed! 🙂👍

hi. since this isn't evap cooling it works pretty good almost anywhere. it does work better in drier areas but only because it's easier to cool (or heat) dry air than it is to cool or heat humid air. still should work pretty good even in high humidity though 👍🙂

@@desertsun02 I agree, it would cool the hot saturated air,but it would feel kind of swampy a front of that cooler..Unfortunatelly the best solution here(south FL) is to dehumidify the hot swamp air and then heat it a little bit inside the ductwork(attic does the heating) so it goes inside the house cooler and drier like 60F,but it does take energy, to lower the cooling demand it is wise to address roof and insulations first,..Anyways, this is really good idea for hurricane emergency cooling, if you have solar backup or generator to make ice.Indirect evaporative cooling is still the best energy wise, the problem is to get the water chilled for long time.

hi. it is aluminum radiator. (but copper one should work too) 🙂

hi. i'd say give it a try 🙂

Hi Did you try using the car water radiator ?

hi and thank you!

the pump i have is an 8mm (5/16") one i think if you use a clamp it fits good.

@@desertsun02 Thanks!

hi. i don't get any condensation (because i live in an area with low humidity) but you could make a simple drip tray *or possibly just set it on a towel or plastic sheeting

simple answer; the air won't be as cold blowing out if it unfreezes slower. I'd try setting fan to lowest speed first and running a secondary fan away from the radiator to just help cool in general unless you are fine with just slightly cooler and lasting longer.

hi. it's pretty strong. it cooled the room in a couple of minutes. i haven't done all the timed tests but i know when a just added one more freezer pak i got about 20-25 more minutes. if you can secure a good source of cold water or ice - you're all set for continuous operation. others will want it for cooling just a few hours here and there - hot parts of the day

@@desertsun02 I believe if you use a picnic cooler with well insulated drilled holes, could maintain the ice packs for a long time. Also you would have a nice flat surface to glue the fan on making a nice portable unit.

i have considered that a few times but i've never tried it. should work good.

hi. it all depends on how 'solid' (and cold) your cold water source is. this design is a powerful air cooler. but with that cooling power, it warms the water pretty fast (as it pulls the heat out of the air). bottom line is: if you keep it stocked with cold water (and have relatively low humidity) - it works roughly as good at cooling air in a room as an 8000 to 10,000 btu ac. (in terms of square footage it covers and overall drop in room temperature). note that that is the 'best case' (meaning with water temp 35F, humidity 5 to 10% and fan on low). if the water source is cool but not super cold or you have high relative humidity it will work more like a 6000, 4000, 2000 or 1000 btu unit *proportionally on down. it's really just proportional to how hot the room air is, how humid the air is, and most importantly how cold your water source is. the main thing though is just keeping the water cold. the colder the water the colder the air. btw the reason humidity is a factor is that it is harder to cool down humid air than dry air. note that this type of cooling doesn't remove humidity from the air but it doesn't add any either. that will stay about the same. that's about the only advantage that standard AC has over this.

Awesome, thank you! I will have access to an ice maker, and a freezer in the lounge right outside of my room, So hopefully the freezer and ice maker will be able to provide enough ice

@@calebb3068 maybe if you have a hose running long enough keep the water near the cooler and cut the middleman

hi. there is no comparison. using a radiator is 10 times better. the copper coil works but there are no fins with that one so its use is limited.

hi there. hey, that's awesome that you built it and it's working good! i wouldn't bother using peltier with this. those take a long time to cool things down. this unit would overpower those very quickly. also they would just add hot air into the room. you could exhaust the hot air out of the room then they might help a little...

@@desertsun02 Thanks for the reply I appriciate your input. I think I might buy a mini-fridge so I can keep more ice packs to prolong each ice refill instead.

keep the fan unit inside the house and the bucket outside with peltier attached.

hi there. sounds like a good idea.

It definitely would, but keep in mind the ice is already running out very fast in the current design. At a minimum it needs more insulation and a bigger container to store more ice. What a lot of other designs I've seen do is use an ice cooler to store the ice.

if you mount the radiator on the other side it acts like a 'wall' - and blocks about half to two-thirds of the airflow. (it still works but airflow is greatly reduced)..

@@desertsun02 that doesn't seem to make much sense really... please explain how configured everything on the opposite side could block more of the airflow?

​@@ihatesignupsgrrrrrrrI've tried it and airflow is very bad. Seens like Radiators are designed for air to travel up and down and exit both sides. Air just seems to come out the sides instead of straight ahead, when you try to force air through.

@@overnightdelivery Thanks for the response!

hi. it all depends on how much ice you use (and how hot the air is in the area). i've gotten anywhere from 30 minutes (few trays of ice cubes) all the way up to 11 hours. (11 hours was 2 big blocks of ice).

hi. it's just plugged into the wall. you can easily run it off of an inverter if you want to. box fans generally use under 100 watts even on high. so even a smaller inverter will run it

hi. i never have that issue where i live. typically doesn't happen unless humidity is over 70%. if you have any - i'd say just put a towel under it and you should be all set.

hi. the coroplast is to block the air from going around or circumventing the radiator. if you have condensation consider putting it on a towel. it should only be a few drops so a towel or even a piece of plastic should catch it ('drop cloth' plastic is a possibility)

hi. electric ice chest. sounds like a good idea. these things blow super cold air if the water is cold. (even colder than AC in some cases) because AC will only blow 15 to 20 degree cooler than the ambient air that it is cooling (whereas this can blow much colder air than that)

fan into fan - like a pre-cooler. interesting - i'll give it some thought. the shirt is long sleeve but it's just a thin t-shirt material and i often pull up the sleeves. but you are right though, a regular t-shirt probably is cooler

those cheap corded drills sometimes last a very long time. my cordless one 'crapped out' twice. i may just stick with the corded ones.

hi. i like putting them on the back. the air flows faster and smoother that way. you could put them on the front if you wanted to. I've never tried them on the front and back at the same time so i'm not sure what the result would be. it might get cooler but you'd probably go through twice the ice.

I've never heard that. Thanks for sharing.

hi. the styro-foam blocks keep the radiator off of the back of the fan (so no water gets on the fan). if you do get any condensation on the radiator, it will just drip straight down. you can set the fan on towel if needed but i never have any water buildup.

hi there. yep, i've used ice chests too.

hi yes, i usually get several hours of cooling at a time before ice needs to be added. it will depend on how hot the room is and how fast you run the fan. the slower the fan speed the longer the ice will last. the fan on low can get you double the cooling time of the fan on high.

sure, you can make it any size. you could use a drum fan and a giant heat exchanger if you wanted to. they sell huge heat exchangers (up to 36" by 36") at 'badger insulated pipes' website. you'll need a large source of cold water.

@@desertsun02 like a big yeti cooler or bigger?

@Ronnell James if you were using those large industrial heat exchangers (like a 36"x36" one that badger sells) you'd probably want to tap into a large source of cold water (like underground well or a pond.) - but some of those yeti's are pretty big so they might work too

hi. it's attached with what are called worm gear clamps. a few of those come with the radiator. you can also get them at the home and hardware stores if you need to. the hose attaches one radiator to the other. it kinda makes it one big radiator

@@desertsun02 Oh!!! That makes sense! I thought it was some kind of handle 😜

@Sharon Metzner 😐🙂⭐

hi. that varies quite a bit - but if you have a balanced system you can get several hours

i'll stay in the desert but i wish i had access to their ice

hi, it will depend on the humidity level where you live. it doesn't happen where i live due to how dry it is. that's why i put the radiator on those little styrofoam blocks though. that will keep any condensation away from the back of the fan.

hi. i just used 2 or 3 ice paks with 36F water and got maybe 45 mins to an hour. use more or less ice for longer or shorter times. or buy a water chiller and tap into that for easy continuous operation. one tip: run the fan on low and it lasts a lot longer. even on low box fans push 1000 cfm or even a little more. i wish i could run it even slower

@@desertsun02 Have you tried using dry ice? Might last for quite a while

hi. the copper tube ones only work a little bit. this works much better. (mainly because of the fins)

Thank you! I will keep looking for solution then. Love your videos 👍

hi. i've only used water. 👍

hi. i don't have the condensation issue but it's certainly an option if you have high humidity. as designed, the radiator is mounted off the back and away from the fan so most condensation will just drip downward. may need a drip tray but that would be simple to add. my drip tray would just be a towel

hi there. nope, it's a closed loop. water stays inside the radiators

@@desertsun02 thank you so much!

hi there. i have thought of using those (mainly for the water chilling ability that they have though). my icemaker cools a small tub of water in the bottom. it seems to happen fast too. i like to keep links in the comments to a minimum for various reasons... but this one is for sparking ideas so it all good. 💡🙂 ...someone else mentioned using a water chiller (office 'water cooler' type). that could work too or maybe even an aquarium water chiller. i'm working on a DIY water chilling system that will be out fairly soon.

@@desertsun02 Thanks for the quick reply! I removed the link, I added some information to help anyone search though, I really wanted you to see that stuff. That is what I was kind of referring to, 'just the innards' of the ice maker, I knew that 'you' could do it, but it might be too much for those of us that aren't as brave to tackle a large project. While I was on Amazon I looked around at their 'water coolers' too, and I wondered how well that would work. The main reason (I assume) that an ice maker wouldn't be as good is because it takes a lot more voltage to run it. The water coolers (I assume again) would not take as much, as least in my noggin. :) (The office type water coolers were REALLY too expensive though, but still, over the long haul, maybe not) I would like to try this stuff, but being in North Texas with the high humidity it wouldn't work like it does where you are, hence the ice maker thinking. Maybe I don't get it, I just remember that when I was a kid we didn't have A/C, we had the water coolers, the big ones. They worked, well, what they were, they did. :) I REALLY hope to see that you make an inexpensive 'air-conditioner' that is as close to a Freon-driven one, but using COLD water or ice, however it is you would go about it. (One that you would have to replenish every hour) Thank you, Sir, and I appreciate the week-end reply, now I'll let you get back to inventing. :)

hi. yes. it should work great for that ✔

hi. it depends a lot on your normal water temp range. if the water is say 72F and room is 85F you might get 5-8 degrees cooling. if your tap water is in the 60's then you'll get even better cooling. if your sitting in front of it you'll have the 'wind chill effect' also and that makes it 'feel' a little cooler. if the water temp and air temp are the same then there is no cooling.

hi. the radiator is a hayden transmission cooler (model 405). i get them on amazon. ebay should have them too

hi there. top end (ideal) is probably about 1000 cfm (or a typical box fan on low). basically, it's as slow as possible (while still getting the breeze you want). ice lasts longer and air is cooler as fan speed is decreased.

hi there. i just show people how to make the projects (but i don't sell them). i'm glad you're making it. it's one of the best coolers

hi. that's hard to say because it depends a lot on hot the room is and how fast you run the fan.

@@desertsun02 yes very true. Say if the room temperature is 32 degrees cel. and room size is 3Mx3M. Sorry for asking. But since this A/C is made for cost saving therefore we need to know how much we can save.

He said: I did one myself, too

hi. i get the clear vinyl tubing at home depot and/or amazon. the black tubing (and the clamps) actually come with the radiator. if you search for 3/8" (internal diameter) clear vinyl tubing you'll see lots

hi there. i don't get any condensation on the radiator in my area but it can happen in the more humid areas

hi there. i get the pumps on amazon.

sounds cool

hi. if the water is cold enough, i think it would cool that size of room

hi. that is an AC to DC transformer. it plugs into an AC socket but puts out 12VDC. i like the 12v DC pumps because they can also be run on a 12v solar panel or a 12v battery.

sounds like a plan. or maybe you could just tap into the cold water reservoir that those things have.

hi. i haven't specifically measured it, but with a good source of cold water it should cool at least 250 sq. ft. and possibly quite a bit more
