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 coolers, also known as swamp coolers, are environmentally friendly, cost-effective ways to make your home and outdoor areas more comfortable. A good evaporative cooler, used correctly ...
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.
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.
The expansion valve partially vaporizes the refrigerant cooling it via evaporative cooling and the resulting vapor is cooled via expansive cooling. (This is a combination of Joule-Thomson cooling and work done by the expanding gas, both at the expense of the internal energy of the gas) The cold, low pressure liquid refrigerant will now absorb ...
These coolers have a water tank in their base that you can fill up manually, or hook up to a garden hose. A pump circulates the water, speeding up the process of evaporation.
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 ...
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.
