Homemade Portable Air Conditioner DIY - Coldest One Yet!

This is the coldest diy homemade, portable air conditioner. Made from an ice chest and powerful marine blower, this air cooler is strong enough to cool a small room. Super cold!

Here are the products I used:

Buy the items below in the concrete section of your local hardware store:

The mesh will be a lot more than you need, but it is only $10 and you can use it for other projects.

DO NOT USE DRY ICE!!! When it dissipates, it will fill the room or vehicle with CO2 which will displace the oxygen causing you to suffocate, pass out and possibly DIE!!!

Wow, dude. You definitely started a trend with this. If you follow the link you provided to the marine blower, the "frequently bought together" shows the blower, the cigarette lighter chord, and the metal shelf! Nice job!
This is an absolute genius idea. I will definitely be running out to build a couple of these, One for our kids room, and one for our room, and will probably bring it with us for long drives FOR SURE! Thank you for this, man!!!!

Much better idea and more practical than an old refrigerator radiator!! Good idea!! Redirecting the air under the ice makes all the difference.

I have a 26ft pilothouse boat that I really didn’t want to put a permanent AC in for just summer month usage. This is perfect. Portable. Light weight. I will try the half frozen bottles half ice trick and see what’s the difference. Thank you for making this video!

This design also seems to solve the leaking problem some people have with similar designs, where they put the blower down lower, and as the ice melts, they have leaks. This seems to not be the case here, which I like. Also looks quite easy to make and use.

That's the best one yet! I've been making these type of things for years and that really is an awesome design

Great video and design. I would like to see a follow up video with the outside temperature, ambient room temperature readings before during and after, temperature readings of the intake air, temperature readings of the out put air, volume of ice used and total running time before the air until the output air reaches 60 degrees F.

These readings should answer the majority of the legitimate questions here in the comments.

Thanks for the build and the video. Keep up the great work.

(Edit). Also the readings of the unit before ice is added. The control readings to show its performance.

Thanks! I can't wait to make one for myself. I'll be heading to the mountains soon and this baby will be a dream come true!

[davepierce]

Very well done ! great video too. Short and directly to the key details. I made something along these lines several years ago with acceptable results, but your idea about directing the air below the ice is truly innovative with minimal additional $'s and time. Thank you !!

A better design for this would have a 'closed' system - i.e. have a sealed aluminium duct that flows UNDER the ice at the bottom of the cooler (couple of those type projects on here) - that way you aren't pulling the hot air directly through the ice itself, so not only will it reduce the amount of moisture it's putting in the air, also the ice would last a bit longer - and you could use cooler blocks / frozen salt water bottles aswel as bagged ice

[ernievilla]

Fill it with frozen water bottles the ice lasts longer and u have something cold to drink

[malcolmporter]

Blowing under the ice is a great idea. One suggestion is a cap for inlet and outlet when transferring it when not in use. Adding a filter at the inlet would also keep bugs n debris from being sucked in.

perfect to put in a grow tent to cool it during the summer

[mikedort]

Sir... your idea is ABSOLUTELY BRILLIANT!!!... The key to your idea is the one way blower fan... I've created my own variance of your idea but you using the one way blower fan is the KEY. Thank you much😊

[MegaKB]

Thank you for sharing your cooler project.
It's obvious that it's a great simple design

[jamessouza]

I made a really large one very similar to the one shown here to store the bodies in. I need to finish the one that I've recently been working on and soon!

Air conditioning requires dehumidification. This not an air conditioner. This is a humidifier. You are very creative and very intelligent. Your design skills are impressive. The quality of your video was also excellent. Thank you for posting.

Thank you for all your hard work, efforts and research and putting a practical, economical working unit literally into our hands. There are lots of ppl that now live in vehicles that don’t have to suffer and have relief. Those that use theoretical criticisms and condemn the efforts without actually building something should move out of the way for those that build something and at least make an effort. Textbook knowledge of btu’s and thermodynamics can be whatever they are but laws and outcomes changes when motions are made and adjustments are also made. It’s one thing to be stagnant in knowledge and another in real time applications. Your project here given to the world here was created in your head, constructed with your hands and perfected with your heart, thanks for being a doer…

[mrJoker]

Nice to see someone who understands how much of a difference that airpocket on top of the ice makes.

[SenthilRatnasabapathy]

Thank you for the video. Very interesting. I guess this is good for hot dry climates, but not for hot humid conditions.
