check out my other videos if you like fireworks, solar, air conditioning for free(not evaporative) etc
great results, from what little I would know. Question, how efficient is this build? Does if consume much electricity?
If you want a cheep source for 134a thats what is in air duster.. Most dusters contain one of two chemicals: tetrafluoroethane (HFC-134a) or difluoroethane (HFC -152a).
can of air duster is usualy 2-4 bucks
That's awesome bro.very very well explained and that's extremely important.verry kool and im subscribing right now and please keep these kind of videos coming for us build it yourself guys and gals..well done.thank you .full time homeless vanlifer.wooooo
@@linearburn8838 that's good to know
I like how this is a true AC and not a fake Peltier or ice based AC
Yeah, I think the pettier ones are decently cool, but whenever I look for a video like this, it always comes up with the stupid cooler ones.
Peltier based would be cool though
Peltier ones are just extremely inefficient @@CrobinHood8BitGuy
As someone who is certified to work on these systems, I think it's really cool that you made it work with those parts! Good idea using that syringe cap as a metering device. Very creative. I'd love to see how it does with a fan running on the evap coil. That being said, there's a few things I don't like that I feel should be addressed.
First is that you lost a lot of refrigerant. Some loss is to be expected, but losing the whole charge multiple times is just negligent. 134A is a greenhouse gas after all, which is why it's beginning to be phased out and replaced with eco-friendlier HFO refrigerants. You didn't remove the air from the system first either. Not only does it ruin the performance of the system, but it also ruins the refrigerant.
Second, when you mentioned that you can use any refrigerant. If you put R410A in that system for example, you would blow every line and maybe even that condenser coil due to the much higher pressures. If you put propane (R290) or butane (R600) in it, there's a good chance it will literally just explode into flames. That compressor is only designed to work with R134A and nothing else. You need a compressor rated for flammable gases to use them safely as refrigerants.
Other than that stuff, cool video! I always liked the idea of clear lines in these systems. They just have to be rated for the right pressures so they don't pop!
Well said Matt, you saved me a lot of typing. I'm what is known in the UK as a Category 1 FGas engineer, while I appreciate the video creator is yound and VERY intelligent for his age it did make cringe for the reasons you pointed out. But well done to the creator if you carry on progressing, find some funding and get the tools and hardware (maybe some refrigerant handling pointers or training) and experiment away, who knows where you might end up if you can make it work with hose pipes!
hi i have made this setup to but properly can you explain to me that when i turn on the condensor fan i get almost no coling but when condensor is hot all of my pipes freazes only for 2minuts help
Kyoto Protocol? Never heard of it 😂
righty but he is making it at home with basically no tools. and i doubt anyone whos able to buy 410 would use it in a rig like this.
Yeah i agree with him. I am also an hvac engineer and i can confirm everything he said.
Nice job! Idea for you: embed your cold side in a piece of concrete and make a cold stone for making ice cream.
yes that would work and maybe a cookie sheet on top
@@ianbuilder You can get a nice polished surface on concrete. Probably don't need anything on top at all
@@Nighthawkinlight ahh so basically pour concrete over the evaporator or just put copper tube through it
Yeah something like that
@@Nighthawkinlight it's cool to see you here 😎
Try copper lines and use a piercing valve so you can pull a vacuum first to remove non condensables. And definitely want to get a fan pushing air across the condensing coil(the big fridge coil)
That's fantastic! Even though I know the refrigeration cycle inside and out, it never clicked for me how simple it is to just do it.
With all the ac systems I fix as a mechanic Iv been tempted to build a system for my home in the furnace to create central air.
if you ever make a part 2, i would recommend using copper lines. they can be found pretty easily. also pull a vacuum on your system before charging, as mixing water and refrigerant can cause a pretty corrosive reaction that could destroy your components. and use pag 46 or pag 100 oil r134a. but pretty impressive though for what it is and the materials used! looking forward to what you make in the future.
Dude, you have changed my life. I can't believe how easy this was
would love see you test the limits, like how much pressure it can take before something gives. also turn on the fan
Awesome. This is true temperature cycle AC.
This is a really helpful tutorial. I'm trying to turn a 12v cooler into an A/C for a teardrop camper. At first I tried just filling the cooler with water and using a USB water pump to transfer cooled water to a 360mm pc radiator with 3 fans, but it's just too inefficient to keep up with the thermal load. It can only maintain a few degrees ∆T. I think the next step is to remove the compressor from the cooler and run refrigerant straight to the radiator like you've done here.
Very nice video!
I am going to try to make a DIY a/c unit for my 30 year old car but I'm thinking of using a belt driven compressor and braided lines
I’m definitely impressed, you know your stuff.
yup for the most part
I've been thinking about turning a window unit AC into a split for my van and this was exactly the kind of video I needed to better understand how all this works. Thanks!
ya go for it
@@ianbuilder What about installing a thermostat????
@@Dan0rioN some simple controller to turn on and off the compressor when cold is needed!
@@waheeddoesstuff depending on the voltage he can make a light switch the shutoff
make sure you buy one that doesnt use a regulated refrigerant. you need a license for those
Excellent. Good clear detailed explanation.
Super impressed. Great video!
Very nice project! And well explained! A tip from me, make sure that you get all the air out before you fill it with refrigerant to keep the pressures lower.
oh wow i never thought of that lol
Thought the same thing as I recharged my cars AC tonight.
@@ianbuilder thats why they vacuum car ac pipes before charging it with gas
The evacuation process, right? Evacuate the air, charge with R134a or whatever and bam ice ice babeh
I am so so happy I just discovered this channel!
Im super excited to build one diy
This is a really cool project, although I'd recommend doing more intensive testing to make sure it can hold the pressure before putting refrigerant in it because that stuff isn't great it get exposed to not to mention the whole hole in the ozone layer thing. Have to admit I want to try this though.
That’s a Coool project.👍 I like to learn to make one for my camper van. Thanks for sharing bro 💕
this makes me want to diy a mini split out of a cheap generic ac:P always thought it should be overall simple but this makes it look even more simple:P; guess best option is evacuate the pipes first but yeah still not so crazy unrealistic as something diy; as the union for the high pressure side I'd try to either buy a compression fitting coupler or flare
i appreciate your video especially with the knowledge that thermal electric needs heavy amp's to drop below ambient significantly!
Thats great this video was my inspiration to make my own mini window unit using 1/4 hp fridge compressor and proper refrigeration equipment.
Really great video man thanks for inspiring
Thanks great job!! Keep doing what you love to . My self was just thinking do a mini split for my SUV car , si l, can sleep over night on my car. But looking for ideas! Help me a lot your video!! Thanks!
Excellent video that explains basic refrigeration theory.
Glad you liked it
Brilliant ! Loved watching this video - Most interesting.
You should add a reversing valve to turn it into a heat pump
would compressed air in the system work or would it have to be a gas? i know air has the cold effect when tipped upside down.
Can u tell me if this things can make a room/living space colder? Coz i'll gonna make one of those if it works .. will add fans for it to make sure room will cooled ..
i never realized it would work with plastic tubing.. now put your radiator in water or somehow keep it cold you'll get to like -40c
Carbon dioxide also works as a refrigerant, but you need extremely high pressure for it to work well
Can you do a video showing us how to make a small anti-gravity space vehicle? Been thinking about getting out of here. Thanks
What ...that's not a rocket science that's a real science
So what Re the compression between Air and proper recommended Refrigerant and also what if you use propen or Amonia etc ?
been looking for a video like this for a long time. thank you
ikr i was looking too. so i just made one everyone uses the inefficient peltier plate ones
@@ianbuilder it also annoys me on some of the 'peltier air conditioner videos' they dont even put the hot side outside of the room they are trying to cool, so the room would actually heat up when testing. Even then, peltier modules struggle cooling anything bigger than a small eski, and might not affect room temperature at all. Ive always been interested in cooling devices for some reason, and maybe your video has inspired me to do something of my own in the future.
@@ElectronicInspiration lmfao ikr they expect it to just magically cool a room with no heat output
first time seeing compressor with flexibles hoses for connections.
Can the car's evaporator core be installed in a propane home air conditioner?
Just amazing
You are smart I like greetings from Indonesia
That was cool bro. Is it possible adding a fan?? Im looking g for a set up for my camper trailer.
cool work, congratulations.

Hey man this is great work! I designed software-controlled AC cooling systems for EV battery packs but never got a chance to do it hands on and want to build my own. This video helped a lot! Would love to see a follow up video to improve the efficiency of your system by monitoring the superheat and using a thermal expansion valve and even a split system!
I have a water-cooled one out and many more to come
nice work!
GREAT BUILD BRO..ILL BE DOING MINE VERY VERY SOON. TO USE IN MY MINIVAN WHERE I LIVE WITH MY DOG CANT WAIT IT GONNA BE GREAT..IM GOING TO TRY TO MAKE A MINI MINI ONE AND SEE HOW MUCH IT WILL KOOL IT DOWN IN A 100 DEGREE SOUTH CAROLINA DAY IN THE HOT BOX ..KEEP UP THE GREAT VIDS.. PLEASE THANKS BRO
If it's not cool, add a Capillary Tube and Filter drier.
What an amazing idea and build! I have a question, can I skip putting the refrigerant in the compressor? Can I run it with just air in the compressor?
Can you try at making a reversing valve for this so its not just a ac but in-fact a heat pump also steel braided motor cycle break line can take the temperatures and pressures im gonna build on with that as the hose and if i can find one cheap use an actual thermal expansion valve
you wouldnt need a txv for this small of a system...his improv orfice hole metering device is fine...a capillary tube would work as well
Would car components work with a fridge compressor? Say for example, I have a car evaporator, expansion valve, condenser then I would use a fridge compressor powered by a solar panel. Would that work?
Hose blows up as there is back pressure use pressure regulator with return line this should fix the problem
Nice video, but do you think I can use the actual A/C indoor unit as my evaporator with fridge compressor outside as outdoor unit
Yes you can!
Can you do a better version off this ac project?! Thanks
@Mousa - Simple Projects actually made a homemade window AC with an old compressor and heat exchangers
Propane and butane are flammable gasses.
If you charge your AC with those it's likely it's going to explore or catch fire.
RIP our ozone layer, you should try some getting the correct equipment to form solder joints.
Very cool!
how can u make a condenser big one instead of a radiator fan
Hello how are you i have 80 mm radiator and 1/4 compressor danfoss what will be the capillary size?will it work ?please guide
I was thinking a portable ice maker would be ideal to make a portable air conditioner
You think that two 240x120 mm pc radiators with 12v cooling fans can cool down the hot refrigerant? Or you need a bigger radiator for cooling down the hot refrigerant?
i think that would work
please mention the links of items I should purchase to build this.
You can use any type of gas under pressure...... preferably not a flammable gas.
best stuff i found to use which is cheap and not flammable, air duster, air in a can, thats r152a which isnt much different to r134a
cool video!
seconded - add a marble stone and make some ice cream
Asking again for one more time here 2 months later, do I REALLY need to use high pressure hose or just a normal hose would fully work? I don't want to use a garden hose for the whole system for go kaboom, I'm thinking of high pressure gas stove hose for it but not 100% sure if I had to get a hose specifically for refrigerant systems (Talking about in somewhat long term usage and not will work or not first)
Concept Summary: A compressor-based personal space cooler that uses a compressor and a condenser to cool the air. The compressor and the condenser are placed outside on a window, and connected by a high pressure hose. The indoor unit is a modified desk evaporative swamp cooler (specifically Arctic Air, the front-side plastic part fan is cut off using a dremel to for a custom copper evaporator to be fit in) and it blows air through the evaporator. This cooler SHOULD be more effective and way more long lasting than using swamp cooler by using an ice + water, and unlike using only water, works in humid conditions.
use high pressure hose
Would ammonia refrigerant work in that system?
I'm seeing so many problems here but I'll let you figure those out on your own since this is a great proof of concept and you obviously have some smarts going on. Just don't let yourself get content and realize there's still a lot of improvements you can make with little to no extra tools and materials.
R135a is cheap as ballz. Even cheaper then a can of much more dangerous bbq propane. The hazard here is enclosed space with limited air and skin damage and lung exposure if pipe breaks but its pretty safe except your high side.
How long is the capillary for use?
Do you think a fridge/small refrigerator compressor will work? And what about cooling down the condenser? Can I attach the condenser to a something like a $15 walmart fan and would it work?
yep this was a refrigerator compressor
@@ianbuilder how about cooling the condenser? I think an actual fridge doesnt use a fan too cool it down, but an ac does
@@Not_Aran8276 should work fine
I've always wanted to see this done with a PC radiator, do you experts know if I can use one for the other side?
it will probably explode
may I know does this unit humidify the air surrounding?
no
It wont humidify the air, if anything it will dehumidify due to the water condensing on the coil if its cold enough
It is very easy to make AC unit. What is hard is to make an efficient AC unit. And it's all about it...
What is brand and model of the compressor?
Hello mate i would like to ask something about that ac unit i want to use 12v compresser for that ac for my boat but im curious is it like that effective also i checked the gas what i can put in the tubes is also 134a type of gas so is it okay and whats your compressor voltage??
let me know if it works i have a sailboat i wanna use it on
Would the compressor burn tho? I mean most of the newer ones does have thermal cutoff, but those teeny tiny compressors aren't really designed to cool a whole room, so I can't imagine them lasting that long
not sure but ive pushed this thing pretty hard i think it has a thermal
I have an idea and i want to try it
What if i replace the car compressor by belt and but compressor like fridge run by second battery with 1000w converter you guys think that would work??
If you had put a vacuum, remove all the air inside of the system then fill the refrigerant the system would cool much faster and you would achieve much lower temperatures.
Really liked this. I know you said the components are expensive, but I've seen another YT where the guy shows building off a used refrigerator condenser coil. The compressor cost? The radiator cost?
radiator was like 20 (computer) compressor was free and so was the condenser expensive bit is if i wanted to make it full coper instead of plastic
How do you figure out how much to add?
It gives me some ideas on how to keep a cpu cold
i just built my first pc and im just now seeing the big debate between water called or air cooled.....i would really like to invent a device that uses freon to cool the cpu, even if you have to put run a small line outside your window or something
Alguém poderia me informar qual a potência mínima de um compressor p fazer este sistema?
Also if you disconnect the high side from compressor and let it go to atmosphere then pinch the high side tubing you will evacuate the air from system then place hose on high side while still pinched. Try and keep air from entering place hose clamps and the charge. It will work way better.
your right i never thought of that
@@ianbuilder please do a new video with the upgraded tips from here
Stupidest thing I ever herd 🤣🤣🤣🤣
How did he draw a vacuum in order to fill it with the gas
And 134a isn't flammable but very toxic to the ozone
Nice
Hi, thanks for the video. If you have a moment , please tell me where you got the small radiator with the fan from. I plan on replicating this.
computer water cooler radiator 120mm by 120 mm
@@ianbuilder thank you
Add a reversing valve and u have a reversible heat pump
How much for the things I need?
Can you make the same video but change it to a DC battery powered portable AC unit? i am off-grid and use solar panels and batteries. And I live in the Mojave Desert, home to Death Valley, the hottest place on earth.
Great vid. Would like to see a video with the split using. Did you make one?
coming up this week
Soo, ever heard of the Kyoto protocol ?
This is extremely valuable in that old fridges are everywhere. Any idea how many watts this consumes? It would be constantly running right? I have an offgrid property in Florida with a tiny 4x8x6 shack under the trees and with a insulated roof and screened walls. I'm looking for a way to cool it down while the sun is out. My power source is a 500w solar panel in the sun. Dumb question but how safe and legal is this?
What's the wattage used?
i would like to make a heat pump, the same way.
HP for compressor ?
I have a question and not sure if I'll get any replies but worth the try. Is this possible to be done without the refrigerant? We only have to keep a 120L storage box to 15C° - 25C° is it possible?
might work
Nice video, thank you. I am trying to make a mini AC with 12V Micro Rotary Compressor. Do you think it will work? BTW: I don't have any experience with Air Conditioning or Refrigeration.
its possible yes
why not add a fan or something as your air handler...and your going to need to put your condenser outside so you can tranfer that heat from your house to the outside air, and also put a fan on that...love the improv filter dryer though
Awesome video man, I learned a bunch! Thanks for making this.
Insane baller using plastic tubing for refrigerant
