Want to Stay Cool During a Blackout? Make a Simple Air Conditioner in Just 8 Easy Steps!

DIY Homemade AC

STEP 6: ADD THE FAN TO THE LID

The small fan that's being used to force the air up from the bucket should fit right over the hole. This will allow cool air to be drawn up from the bucket and inside the room. Warm air will be drawn to and through the screen, followed by the soaked pad. The pad will result in the unit cooling down as it evaporates some of the water during the process.

add the fan to the lid

 

You can easily use some small pieces of duct or gaffer tape which will help keep the fan in place.

STEP 7: PUT THE SUBMERSIBLE AQUARIUM PUMP AND TUBING INSIDE THE BUCKET

The aquarium pump will recycle the water from the bottom of the bucket, and it will also feed it up through about 4.5 feet of tubing.

install the pump

Before going on to the next step, first, you'll need to seal the end of the tubing with a small spring-loaded clamp. When the water reaches the top end of the tubing, it will drip out and saturate the pad through the holes.

You can transform the tubing into a soaker hose after the break and then watch the video to see everything come together. You're almost done with a useful A/C unit that you made yourself!

    This may make you feel cooler but actually adds heat to a room (remember to cool you have to transfer the heat somewhere else). You can make a two bucket system with two fans, one set inside and one out that would actually cool, but you have to connect then through a wall or window somehow.

    Hey that’s no joke. I actually built one of those last year and bought the copper, water pump, etc to Julie another one here just in case. Lol

    We used one where i used to work in va. Feels about 5 to 10 degrees cooler. Its a swamp cooler and when its 90+ makes it feel a little better but its not an air conditioner and uses the water quickly.

    Swamp cooler, not air conditioner. It puts humidity into the air, which makes things worse here in the south

    It’s not A/C, it’s a swamp cooler. They can be useful, so long as you don’t have high humidity already.

    Yeah during a blackout I’ll just go out and get myself a shovel full of snow

    They don’t create high humidity, but they will raise it up to normal levels in especially dry areas. They use evaporation for cooling, so as long as the water is evaporating, it’s cooling. 🙂

    Only works in dry places, not in humid climates like you’d need. Also, I’ve made a few ice A/Cs different methods, and they are very inefficient. A whole cooler of ice barely cools a small cab pickup for maybe an hour before it all melts. Best bet is to find a way to run coil through whole… large blocks. Still were fun to make though.
