Over the summer, my room can get pretty hot considering I have a computer and RGB strips everywhere. However, my family won't let me use the air conditioner because it waste money. They always say just turn on the fan, but they don't know that with hot air in the room, a fan just recycles that air by blowing hot air around the room. My solution was to find old parts around my house and make it into a makeshift air conditioner that is portable and can be plugged in just like a fan.
3/4 PVC pipe
Dry Ice/ Frozen Water Bottles
Knife/ Foam cutter
Step 1: Measure the Fan
Depending on the size of your fan and the size of your box, your location of the fan will vary, I suggest the top of the box or the side. In my project I used the side of the box just because the fan would only fit on the side. You want to lay the fan on the surface that you want the fan to be located at and trace the size of the fan.
Step 2: Cutting the Box and Attaching the Fan
After tracing the shape of the fan, start by cutting the shape out with a knife or a foam cutter.Cut this all the way around and pop the shape out. Use a vacuum and clean up the excess. After this, duct tape the fan to the whole and make sure to seal off any holes.
Step 3: Preparing the PVC
After preparing the fan on the box, take out your PVC and measure out your pipe. I went for 3" each piece with 3 pieces. You can do more pieces or longer pieces, but that is up to you.
Step 4: Cutting PVC
After measuring out the pieces, cut them out with the hand saw and sand them out. You can use sand paper or a sander if you have one, but for me i don't so I scrapped it across the concrete for about 2 min and it worked fine.
Step 5: Holes for PVC
After cutting the pieces, Trace out the PVC on the side of the box you want the air to come out. After tracing all your pieces, begin cutting it with a knife all the way around. Pop out the pieces and vacuum the excess.
Step 6: Attach the PVC
Use duct tape and attach the PVC at an angle and allow the pieces to point at different angles. Make sure to cover up all the spots that air can escape. Tape all the pipes and make sure they are secure.
Step 7: Add the Dry Ice
After all this is done add Dry Ice to your fan and it will cool the air. How this works is the Dry Ice is cold enough to cool the air that the fan adds in and shoot it out the PVC side. You can find Dry Ice at a local super market, I got mine at an Albertsons. If Dry Ice is to expensive or you don't have access to Dry Ice, frozen Water bottles will work just as well. The only difference is Frozen water bottles will melt and create residue. Overall it works great, I have an average sized room, and it fills my room with cold air in about 5 minutes of it on.
