When the weather in Indonesia’s territory, especially Surabaya, gets heated up, the use of air cooler is one way.
However, the use of air cooler will certainly be taken into consideration when the basic electricity tariff is high.
So, is there another solution to keep the room cool in this hot condition?
Reporting from vankool.com, in Bangladesh a tool has been found to keep the room cool even though it does not use tools such as fans or air cooler.
Understandably, Bangladesh is an area that has not been touched by electricity.
Even if there is electricity, the cost of paying for electricity will be very expensive.
Bangladesh is famous for having quite hot weather.
It was recorded that during the summer of 2016, the average temperature in East Pakistan had reached 45 ° c.
Although various conditions seemed to not support them, the big idea turned out to be born from that situation.
One of the poorest citizens of Bangladesh was created to make air cooler with plastic bottles that are easily found everywhere.
This innovation was first coined with named solar cooler.
The workings of this tool are calculated to be very simple, and can even be done by anyone.
The basic working principle of this tool is the same as when we try to blow our hands with our mouth open and blowing our hands with our mouth almost closed.
There will be a difference in the air produced by the blow.
It is the same as when the end of the cavity where the air flows gets narrower, the air will experience a decrease in temperature.
This basic principle is used by Ashis when creating an Eco-cooler.
Eco-cooler uses only the middle to the top of a plastic bottle.
The neck to the mouth of the bottle becomes an area to reduce the temperature of the air, while the stomach of the bottle as the entrance gate for air.
The plastic bottles that have been cut are then mounted on a board that has been perforated as a place to stick the bottle mouth.
The board that has been fully attached to this plastic bottle is then placed as part of the building wall.
That was what Prof. Dr. Syafaruddin ST M Eng did. The Electrical Engineering lecturer developed the ” air cooler System with Solar Energy.” He created air cooler by utilizing sunlight as an alternative energy source to save electricity and be environmentally friendly.
“This solar energy has enormous energy potential to be used both for electrical energy systems, heating …
