When it comes time to cool your home during warmer months, you may think your only options are an air conditioner or a box fan, but there’s a third choice: an evaporative cooler. These coolers ...
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.
Air conditioning can be achieved using a mechanical 'air conditioner' or by other methods, including passive cooling and ventilative cooling. [ 2 ] [ 3 ] Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC) . [ 4 ]
Because the cooling water, which is chemically treated fresh water, is at a temperature of 70–80 °C (158–176 °F), it would not be possible to flash off any water vapor unless the pressure in the heat exchanger vessel is dropped. A brine-air ejector venturi pump is then used to create a vacuum inside the vessel, achieving partial evaporation.
An air conditioning system, or a standalone air conditioner, provides cooling and/or humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions.
If the evaporative cooling chamber is not built 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.

Have your air-conditioning system serviced according to the manufacturer’s instructions. Some types of filters, for example, are designed to be disposable, while others are designed to be reused ...
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
