The title is correct. This Evaptainer refrigerator is indeed a refrigerator that does not require electricity to keep food fresh. It was designed by a student named Quang Truong from the Massachusetts Institute of Technology. Evaptainer does not have a water pump or fan, but uses the principle of water evaporation and cooling for cooling. It can use water and sunlight very efficiently.
The Evaptainer shell was originally made of a ceramic layer material fired from clay, with a layer of wet sand inside to evaporate water and insulate, keeping the inside of the refrigerator at a low temperature . But in order to make the refrigerator less likely to be broken, it was replaced with aluminum plates and special outer shell fabrics, which can effectively dissipate internal heat outwards. The Evaptainer has a capacity of 60L and is used to hold apples or oranges. It can hold about 150 apples or oranges. You only need to pour about 6L into it to keep food fresh for 12 hours. It is very suitable for picnics or long-distance transportation of vegetables, fruits, and meat.
Quang Truongs goal in designing this electricity-free refrigerator is not only for daily freshness use, but more importantly, he hopes to effectively reduce the occurrence of food spoilage in developing countries and avoid causing Food waste.
