In dry, arid climates, the installation and operating cost of an evaporative cooler can be much lower than that of refrigerative air conditioning, often by 80 % or so.

Traditionally, evaporative cooler pads consist of excelsior ( wood wool ) ( aspen wood fiber ) inside a containment net, but more modern materials, such as some plastics and melamine paper, are entering use as cooler-pad media.

* High dewpoint ( humidity ) conditions decrease the cooling capability of the evaporative cooler.

* The air supplied by the evaporative cooler is typically 80 – 90 % relative humidity ; very humid air reduces the evaporation rate of moisture from the skin, nose, lungs, and eyes.

A ceiling fan rotates much more slowly than an electric desk fan ; it cools people effectively by introducing slow movement into the otherwise still, hot air of a room, inducing evaporative cooling.

Before the advent of refrigeration, evaporative cooling was used for millennia.

When the ambient temperature is excessive, humans and many animals cool themselves below ambient by evaporative cooling of sweat ( or other aqueous liquid ; saliva in dogs, for example ); this helps to prevent potentially fatal hyperthermia due to heat stress.

The effectiveness of evaporative cooling depends upon humidity ; wet-bulb temperature, which takes account of humidity, or more complex calculated quantities such as Wet Bulb Globe Temperature ( WGBT ) which also takes account of solar radiation, give a useful indication of the degree of heat stress, and are used by several agencies as the basis for heat stress prevention guidelines.

Remediation for Legionella outbreaks in commercial buildings vary, but often include very hot water flushes ( 160 ° F ; 70 ° C ), sterilisation of standing water in evaporative cooling basins, replacement of shower heads, and in some cases flushes of heavy metal salts.

This causes heat loss via evaporative cooling ; however, a lot of essential water is lost.

Biofouling of heat exchange surfaces can reduce heat transfer rates of the cooling system ; and biofouling of cooling towers can alter flow distribution to reduce evaporative cooling rates.

In an interior space cooling unit, the evaporated water is introduced into the space along with the now-cooled air ; in an evaporative tower the evaporated water is carried off in the airflow exhaust.

With evaporative cooling heat rejection, their coefficients-of-performance ( COPs ) are very high ; typically 4. 0 or more.

This differential can be generated without evaporative cooling in the head ; for instance, a heat source directed at the bottom bulb will create a pressure differential between top and bottom that will drive the engine.

The 1571 was noticeably quieter than its predecessor and tended to run cooler as well, even though, like the 1541, it had an internal power supply ( later Commodore drives, like the 1541-II and the 3½ " 1581, came with external power supplies ).

In practice this made possible the tracking of cooler targets over longer ranges, and enabled forward-hemisphere engagement of jets under favourable circumstances. The seeker also had better tracking rate, enabling the missile to track maneuvering of fast and approaching targets.
