Evaporative cooler

Energy-efficient cooling system in which a fine mist of water is evaporated, lowering the air temperature. Evaporative coolers are most appropriate in dry climates, because they add humidity. Also known as a swamp cooler.

Higher RH values and lower temperatures were found with evaporative cooler, providing better environment conditions for pigs compared with the environment without cooler.
Now, newer designs called "indirect evaporative coolers" are on the market.
In the next step, the air becomes cold because of the evaporative cooler; then, the air moves into the room as supply air.
This is where interior cooling is most sorely needed, and the best that can said for an evaporative cooler operating in a 72[degrees]F WB temperature and delivering 85[degrees]F to 90[degrees]F air is that it's cooler inside than it would be without evaporative cooling.
Figures 1 and 2 show a schematic diagram of the forced air evaporative cooler [15].
In Laredo, evaporative coolers (a low-technology air-conditioning device that cools and humidifies air by drawing it from outdoors through a continually wetted screen) were less prevalent, a greater proportion of houses had intact screens, the average distance between houses was greater, and fewer persons lived in each house (Table 2).
To get the most benefit out of the Rigid Media Direct Evaporative Cooler (DEC), it is often combined with an Indirect Evaporative Cooler (IEC).
* Direct evaporative cooling, as in the typical evaporative cooler (sometimes called a swamp cooler), outdoor air is contacted with water reducing the temperature from the dry-bulb temperature to a lower temperature approaching the wet-bulb temperature.
Power consumption of a misting system or an evaporative cooler is considerably less than that used in conventional airconditioning.
Another option for those in hot, dry climates is an evaporative cooler, which cools outdoor air through evaporation and blows it inside the house.
Mounted to a fuel-powered portable product with a thermal link to the electronic section requiring cooling, the evaporative cooler features a modular configuration of aluminum fins with etched microchannels.
