Evaporative Cooling Without Electricity

Scientists cooled water without electricity by sending excess heat where it won t be noticed space.

Evaporative cooling without electricity.

A wet bulb temperature is an indication of the amount of water vapor relative humidity in the air. For this reason the amount of heat flow off the earth that goes to the universe is enormous. Methods of alternative refrigeration passive cooling. Evaporative cooling is limited by the current wet bulb temperature.

Here are three methods of alternative refrigeration you can use without electricity. A cheap pvc shelf unit from you local hardware store works well. If you have something that is very cold like space and you can dissipate heat into it then you can do cooling without any electricity or work. Several hot and dry regions throughout the world could potentially benefit from evaporative cooling including north africa the sahel region of africa the horn of africa southern africa the middle east arid regions of south asia and australia.

The system cools water flowing through pipes connected to an air conditioning system without requiring electricity by radiating excess heat from water into cold space. The specialized optical surfaces they developed are a major step toward applying this. The heat just flows explained fan who is senior author of the paper.
