the water's latent heat of vaporization is being pulled from the air, the water pulls heat from the room to undergo a phase change.

Swamp coolers only work well in areas with low humidities, such as the desert. They are only capable of lowering the temperature by about 20 degrees if the humidity is quite low. An air conditioner would be much cooler.

Hi, Swamp coolers are not a big thing in my area because of the high moisture content normally in our air.They are most effective in very dry hot air climate situations.The answer to your question is rather simple because the whole purpose of the system is to evaporate the cool water by the dry air which in turn has a refrigerating effect on that air.If you do not have adequate outlets then the air will become saturated and humid and moist rendering it not only but humid as well eventually.Things need to be balanced for best operation and most efficient operation to be achieved.To much of anything is not good, but, then the opposite also holds true.In the world of engineering you find everything to be a compromise.Its always variable and a give and take.Same goes for your system.Imagine yourself as the engineer and using a very high tech piece of analyzing equipment to set your system to its best point for your likes.( Your Body Senses being the test instrument) Hope this helps: Jimiwane

You can install an evaporative cooler. They are only effective in very dry areas. If the humidity regularly gets high, they are not effective in cooling. For more information you can visit the swamp coolers page at www.hvac-for-beginners.com
Swamp coolers depend on evaporation of water to cool the air. The hotter the temperature and drier the air, the better they are able to cool.
Air coolers are not effective in humid conditions, so are not suitable for Kolkata. Air conditioners are what is needed.
Swamp coolers, is a term that refers to a cooling tower composed of a device that moves air through a medium where water passes over. These swamp coolers work well to add moisture to normally dry air. This type of cooling system are usually found in very dry climates and cost very little to operate compared to air conditioners.
Mosquitoes are attracted to the water inside of swamp coolers. The present insects should be removed and a safe mosquito repellent should be used to get rid of them.
Answer Arizona roof air These are probably evaporative coolers, also called swamp coolers. They cool by evaporation. In dry climates they are very effective. They cost almost nothing to operate. Cool air falls and by being on the roof the unit is exposed to the sun for the longest time. --- Az resident editing this to clarify the answer given. Yes, many homes have "swamp coolers" on the roof and for the reason given. However, many homes built in the 80s and 90s also had the AC unit/heat pump on their roofs. I have two units on my two story homes roof.
The evaporative car coolers, Also known as swamp coolers, from the 50s and 60s are well documented on the net. I would base mine on one of those designs.

There are a couple options for buying water coolers in bulk or wholesale online. This website offers wholesale options to businesses for traditional bottled water coolers http://www.coolerdirect.com and this one offers the alternative, cost effective filtered coolers, at bulk prices http://www.quenchonline.com/
They are already humid. thus evaporation has little effect.
Central air conditioners tend to be more expensive than swamp coolers. This is usually because people prefer to pay more for the comfort of central air.
