Abstract: Summer is in full swing and many of us are complaining about the heat. But few places reach the scorching temperatures where air conditioning is simply not an option for most people living in rural areas. A clever DIY cooling system that does not require electricity is built from common waste items such as empty plastic bottles. We call it a eco cooling system. The working is based on the principle that when the compressed air expands through the nozzle, the swirl motion is created. The air moves as a free vortex from the nozzle plane towards the valve end. As it reaches near the valve, the kinetic energy is converted into the pressure energy giving a point of stagnation. |
Keywords and phrases: development of artificial cooler, waste bottles, unused cardboard, eco cooler.
