However, it may not be suitable for people who are sensitive to colds or have respiratory problems.


  • Expanded polyethene box: it is important that the box is large enough to hold a medium-sized bag of ice without it touching the fan.
  • Ice bags
  • American tape
  • A PVC pipe elbow.
  • Small electric fan
  • Paper aluminium

Steps to follow

The first thing you have to do is to glue the aluminium foil to the walls. This way, it will make the room to have more heat resistant and waterproof. Use duct tape to stick the aluminium foil to the wall and make sure the joints are tightly closed.

Drill two holes in the box’s lid, one the diameter size of the tube and the other the size of the fan. The tighter the holes, the better the appliance will work so that there will be less leakage.

Insert the tube and fan into the holes and fix them well. Ensure that the fan draws the air out of the case and not the other way around, which is an essential part of the process. Leave the fan cable out of the box.

Place the box near an outlet.

When you want to use the appliance, put the ice inside the box, cover it, close it with duct tape, and plug in the fan. The cooling effect will be immediate, and the drop in temperature will make the room habitable.

If we have the heat problem in the car, we can build a small device, similar to the previous one, adapted to the vehicle’s air mechanism.

  • A beach cooler
  • Multiple computer fans
  • A car radiator
  • A car or appliance water pump

Steps to follow

First, place the water pump inside the fridge to create a closed circuit of water that passes through the refrigerator and connects to the radiator.

Fill the fridge with ice.

Place the fans on one of the refrigerator walls, so that they take out the air.

Connect the fans, and the water pump to a jack plugged into the cigarette lighter socket (both the fans and the pump are prepared since they are 12V), and we already have a portable air conditioner.

Air Conditioning without Ice

The above devices, although practical, have three drawbacks:

  • They use ice.
  • Its effectiveness only lasts for a little while.
  • Consume electricity

On the other hand, the homemade air conditioning that we propose below is entirely independent. It can be used anywhere without using any power or fuel. It is also manufactured with recycled materials.

Its operation is based on the principle of pressure cooling, which can be checked very thoroughly: 

if you blow with your mouth open, the air will come out hot, while if you blow with your mouth almost closed, the air will come out cold. 

Therefore, if you channel air through a large opening into a small one, it will cool down as it compacts. And, what is even more interesting, in times when the environment is cooler, you can reverse the air circulation by turning the board and achieving the reverse effect.

Plank – the size of a house window (the one you will use as an air source). (The plank can be made of any material, but it must be an easy-to-drill and rigid material.) 

If it is transparent, it will allow light to enter, but transparent materials are usually less malleable than wood, for example.

Plastic bottles with screw caps (better if they are all the same).

Contact tail.

Steps to follow

  • Cut all the bottles in half.
  • Remove the plugs and use one to mark circles of that size on the board, forming lines. Cut out the holes with a drill or similar.
  • Glue the holes’ outline and place the bottlenecks in them, so that all the “asses” are on one side of the board and all the “mouths” on the other.
  • Close the bottles with the caps.
  • Place the plank in the window opening, either permanently, with nails, or with a temporary fixing system, such as mosquito nets. 

The caps should be towards the house’s interior so that the air enters through the wide part of the bottles and is compacted and cooled before entering the room.

Although the temperatures that the air reaches in this type of air conditioning are not very low, they are nevertheless close to those of the air conditioners that are marketed, but with zero consumption and the advantage of regulating the amount of air with ease. 

Regardless of the air temperature outside, the air inside will always be cooler.
