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, 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.

The Unit being in Sun or Shade will have NO effect on how well a Swamp Cooler performs. Operation of Swamp / Evaporative Cooler effectiveness is determined by Ambient temperature / dew point and relative humidity. They are optimum in Dry / Hot / Low Humid climates such as found in the South West Desert areas of the U.S. The higher the Humidity / Dew Point, the LESS EFFECTIVE a Swamp / Evaporator Cooler will be. They cool by adding moisture to the Air. So the higher the Humidity is, the more the moisture content is in the air already, thus being less effective. Air can only support so much moisture before it starts to condensate. ( You will then start to feel Sticky and less comfortable ) Again, the Unit being in the Sun, verses being in the Shade, WILL NOT change the Coolers effectiveness in operation.

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.
