-Evaporative cooling devices are simple and inexpensive ways to keep vegetables fresh without the use of electricity. Evaporative cooling devices include household capacity clay pot coolers, commonly known as "Zeer Pots," and the larger storage [[Evaporative cooling chamber|Evaporative cooling chamber]] (ECC), also known as "zero energy cooling chamber" (ZECC). These devices function according to a basic principle called “evaporative cooling,” where the evaporation of water from a surface removes heat, creating a cooling effect.

 === Evaporative Cooling Chambers ===
-Evaporative cooling chambers (ECCs) can be made from locally available materials including bricks, sand, wood, dry grass, gunny/burlap sack, and twine. Roy and Khuridiya’s ECC design is composed of a double brick wall structure, supported by a base layer of brick, and covered with a straw mat. The space in between the two brick walls is filled with sand, which retains the water that is added. If the evaporative cooling chamber is not build in an area that is well shaded, a shed must be constructed to provide shade. Inside the ECC, food is placed in unsealed plastic containers, which keep the vegetables off the ECC’s floor and allows them to breathe and be exposed to the cool, humid air inside the device.<ref name="Best Practices">https://d-lab.mit.edu/resources/publications/evaporative-cooling-best-practices-guide </ref><ref>https://www.youtube.com/watch?v=enOjVc-kN7Q</ref><br/>

 Evaporative cooling can improve vegetable [[Cold Storage of Agricultural Products|storage]] shelf life by providing a stable storage environment with low temperature and high humidity, which reduces the rate of respiration and water loss and spoilage in most vegetables. The improved storage environment can have positive impacts including reduced post-harvest losses, less time spent traveling to the market, monetary savings, and increased availability of vegetables for consumption.
