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 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?

@spinergy686 Sorry but I am not sure about this. However I have run an electric bicycle off of 24V with lead batteries using just a toggle switch and I had no problems. I had to make sure the toggle switch could handle the amps and the voltage.

so you gonna stop every 2 hrs to get a bag of ice? $2 for a bag of ice, 4 a day,$8 a day , in 365 days is $2,920 not worth it

@guayacan07 I never bought any ice. Just used the frozen water bottles as shown in the video. I only ran this for a few hours a day and not 8 as you figured. This is an old design that I no longer use.  Recently I built a homemade swamp cooler that I use instead. If you go to my channel you will find the video. This is much better since I don't need ice. Just fill it up with water, and the cooling effect is about the same. Oh, and I got my AC fixed in my car!

Looks nice ! But i wonder can it cool down a normal room? and does the room temperature actually gets lower?

[hutchtransfer]

@Synthbin If this is in a small room then it can cool down the room by a few degrees. However, this is way more effective as a personal air cooler. It does a great job of cooling down your 'personal space'. If you are across the room then you can hardly feel anything, especially if you have a weak fan.

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