Portable 12V Air Conditioner --Cheap and easy!

Step 8 Wiring

It would be difficult to make the make the wiring for a project easier than this. There should be a red and a black wire coming from each fan, the bilge pump, and the 12V plug. Use wire nuts to attach them all together, and make sure the pump and fans are going the right directions. The fans should be blowing out, and the pump should be pumping through the hose. After everything is moving correctly, you can solder the wires together, or put a switch in the power cord. We also used small zip ties to hold the wires together and to the fan.

I would like to see the results of both fans running, one fan blowing and one sucking, and both bans blowing and a small hole drilled to let air in with a flap so the lid can be totally shut during operation.

I think I'm missing something. You had said that both fans blow out? Is there an air intake opening elsewhere? I was thinking that if one fan blows in and the other blows out, there would be unilateral air flow, and the air would be cooled twice, once as it enters and again when it is drawn out. Is that how you have it set up?

Both fans blow out, and the lid is cracked to let in air. Either way works, though.
