In the 1980s, the living conditions of most families were not rich, and there was no air conditioning at home. Fans were a tool to accompany us through the hot summer, but when it was the hottest time, even the fans were blown out The wind is hot. If you put some water on your face, it will be much cooler when you blow on the fan, but this is a temporary solution rather than a permanent solution. Once the water dries up, you will continue to "enjoy" the hot air.
A foreign expert came up with a simple and scientific way to cool down a fan. He DIYed a simple device using a plastic bottle. He put a cover on the fan and the air blown out will be cool. a lot of.
The materials used for this device are easy to find, and it is not difficult to make. You can use 6 plastic bottles and a plastic plate.
First cut the plastic bottle in half (any plastic bottle will do).
After that, a hole the size of the diameter of a plastic bottle is cut on the circular plastic plate.
Put the plastic bottle into the round hole, add glue and tie it with a few zip ties.
Then just fix the plastic plate on the fan grille. It should be noted that the mouth of the bottle should face the direction of the fans air outlet.
After testing, the wind blown out by the fan through the device was reduced by about 5 degrees. Are you surprised? In fact, this device The principle is the same as an ecological air conditioner introduced before.
This ecological air conditioner is specially designed for hot Bangladesh, because the power supply in this area is very poor. Stable, air conditioners cannot be popularized at all. Considering this problem, people came up with this "ecological air conditioner".
It does not use electricity, and the natural wind from outside enters this device , when it reaches the narrow position of the bottle mouth, the air will be compressed, and the blown wind will be cooler, achieving a cooling effect.
Fully considered In view of the electricity shortage in poor areas, this device not only saves money but is also environmentally friendly.
