Desert cooler works on the induced flow system. The fan sucks the atmospheric air across the water wet pads made of fibrous material. The pores in the fibrous pads increase the surface air for better contact betwwen the dry air and water. The moisture content in the air increases & due to it the temperature falls down. This cold air which is also highly humid (due to increase in moisure) is blown in the room by the fan.
Desrt coolers work best on dry air ( low humidity atmosphere) and that is why it is called 'Desert cooler'. Such coolers are not suitable for places where the atmospheric humidity is high.

Fairly popular in desert areas, swamp coolers will work fine most of the time in .... stale air with cooler nighttime air, much like a whole house fan does.
