Homemade Air Conditioner with Car Blower Motor

This is my homemade air conditioner. I built this by starting with a regular cooler and then I cut out a styofoam piece for the lid so I didn't have to destroy my cooler. The fan is a AC blower motor from a Toyota Tercel that I picked up from the junkyard for $5. You can run it off of a 12V battery, however I choose to run it from the wall. I did this by taking an old 350W power supply and cutting off the connectors. Then I connected all the orange wires to the positive motor terminal, and the I connected the white wire from the power supply to the negative motor terminal. This combination gives 8.3V, which is enough power for this motor. You can connect the yellow wires to the positive motor terminal and the black wires to the negative motor terminal to get a full 12V. This fan really pulls in a lot of air and is much more effective than a regular desk fan.

I think its great idea wish I had seen this a few years ago when we had that freak doracial had no power for a week ideal to cool the room down at nite also to keep food cold Ice not a problem I live 1/2 from Ripco ice

rgrhanrgrhan (2 years ago)
If a person used a 12 volt cooler to keep the ice in it wouldn't melt unless it was unplugged.

Shariq MohammedShariq Mohammed (3 years ago)
U cud use DRY ICE

hutchtransferhutchtransfer (3 years ago)
It would work, however you need to make sure you are not in an enclosed room.  When the dry ice melts it gives off CO2 and this could suffocate someone.

have u tried using dried ice inside your cooler? I wonder if it would work better, because dried ice dont melt.

I'd like to know what year the Toyota Terce was that you got the blower motor out of. -thanks

Really nice video. Great idea using a blower motor from a vehicle. It's already matched to run on 12v. I'm using videos like yours to make one for my Durango as the A/C is shot. $1200.00 to fix it! What I'm doing a little different is along with frozen 2 liter soda bottles(8) I'm also laying in some metal lathe to act as like a coil to collect the moisture in humid air and let it condense leaving dry cool air to be blown into the vehicle. Thanks again for your ingenuity.

Not bad sir. The New Macgyver :D

J FJ F (4 years ago)
you'll be fine, but i guess you figured that out already. You'll also only have "high" setting, or if you want to get really fancy, you can rig up 3 switches, one with a single ballast resistor (chrysler electronic ignition style) in series with the motor, and one with two ballasts, and then one straight from the battery. the 2-ballast will give you low speed, the single medium, and no resistor=high speed. they will also add a good bit of heat to your air, so mount the resistors outside the duct

Well he mentions 100 F and many of the viewers are in those climate zones

cyrylthewolfcyrylthewolf (4 years ago)
Does this guy SOUND like he's in one of those climates?

Watch the video but don't talk shit like you expect him to assume YOUR environment. Figure out your OWN solution or adapt HIS. Don't ask him stupid questions.


guayacan07guayacan07 (4 years ago)
Have you heard of different countries and different climate zones? Did you know that some countries ONLY have summer and what they call " winter" is heat with lots of rain?

cyrylthewolfcyrylthewolf (4 years ago)
365 days? Do YOU run your A/C during the fall? How about the winter?

The freezer will continue to be cold wither he is using the ice from it anyway. He is simply using the ice that is already made to further cool his house. Please stop hating, especially considering your not good at it.

HKGammingHKGamming (5 years ago)
Add sugar to the ice so it doesn't melt as fast

suprcustomsuprcustom (5 years ago)
The funny thing is that if the Freezer you use to make the ice is in the same house as this type of cooler you are actually heating your house not cooling it.

That's a lot of power and wiring. But I bet that SOB blows some air.

spinergy686spinergy686 (5 years ago)
I came across your video & I was hoping you can help me. I cannot find the short in my truck blower wiring. If I run the blower straight from the 12v battery with a toggle switch will I be at risk of fire?

RocketBurn11RocketBurn11 (5 years ago)
If you used dry ice would it displace oxygen indoors or would it be too little to matter? Just curious, my dorm doesn't have AC and we can't have AC units so I'm planning to make something like this for next year.

Great vid! and when the jugs melt down you can just toss them back in the freezer and refreeze them then exchange them for prefrozen jugs. Very good idea!

Is there any reason you couldn't use a regular plug in fan for an apartment room? Does the battery make it safer avoiding electrical problems or something??
