An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles.
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.
Cool-Space 400 Evaporative Swamp Cooler. If you need to cool down an especially large area, like a warehouse, workshop garage, or studio, consider this beast.
I feel dumb for uploading the swamp-cooler.jpg image. I assumed (because of the location on my computer) that it was one of the many images I had that were general clip-art and free-to-use images. I think I should be able to just take a picture later this month (when we open up our swamp cooler) and upload it in place of the other image. My bad.
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.
A portable swamp cooler can lower the temperature by as much as 20 degrees, but that depends on how powerful the unit is and how hot and humid the weather is. A small tabletop or cheap floor unit ...
Some modern tests have shown that the interior of the safe would achieve temperatures 3–9 °C (dependant on breeze) cooler than the atmospheric temperature during the middle of the day. [2] It was usually placed on a veranda where there was a breeze. The Coolgardie safe was a common household item in Australia until the mid-twentieth century.
