Homemade Portable Air Conditioner DIY - Coldest One Yet!

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

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!!!

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 !!

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!

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

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

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!!!!

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.

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!

That's pretty smart. And with 200+ cfm's being pushed through a 6 inch pipe the velocity or throw would be outstanding for rapid cooling of an area space while under load. A simple cooler turned into this is freaking awesome lol

Very cool build! You could increase the air diffusion by extending a duct or hose going across the bottom with a series of smaller holes to evenly distribute the air under the ice. Perhaps even a tight mesh could even work? Now I wanna build one!

You, sir, are an innovator! I love your idea, I have made a blower box that doesn’t get as cold but allows for the ice to last longer by using 2 transmission oil coolers to cool the air going in the box and the air going out of the box. The box is connected to an ice chest via insulated tubing that has a pump pumping water from the ice chest to the coolers in the blower box. I use a turbo fan at the exit point. The temp has gotten to the mid 40s, it’s just a proto type.

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

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!

Glad to see someones having fun, your idea got me thinking

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

You should make one that has a variable speed controller for when you dont want to make it that cold or dont want as much air flow

Instead, use one semi-rigid duct from intake to exhaust and coil it in between. Pack ice around the coiled duct. Place the blower motor in the exhaust or blow it through, it's the same effect. This way, there is no direct airflow on the ice (which would melt it super quickly), the ice would make use of the cooler insulation (makes it last longer), there would be limited condensation/moisture that hinders/hampers your blower, and your airflow would only use inline indirectly cooled air from the duct walls. It's simplest and best.

I have all my parts ordered everything will be in this week I’m excited to get this put together thanks for the video
