The evaporative cooler was the subject of numerous US patents in the 20th century; many of these, starting in 1906, [2] suggested or assumed the use of excelsior (wood wool) pads as the elements to bring a large volume of water in contact with moving air to allow evaporation to occur.
Unlike other types of air conditioners, evaporative coolers rely on the outside air to be channeled through cooler pads that cool the air before it reaches the inside of a house through its air duct system; this cooled outside air must be allowed to push the warmer air within the house out through an exhaust opening such as an open door or window.
A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed.

Evaporative cooling chambers (ECCs), also known as "zero energy cool chambers" (ZECCs), are a type of evaporative cooler, which are simple and inexpensive ways to keep vegetables fresh without the use of electricity. Evaporation of water from a surface removes heat, creating a cooling effect, which can improve vegetable storage shelf life.
