the desert cooler works on the principle of spraying atomised water using a pump and a fan.this water absorbs the heat in the room and evaporates,cooling the room considerably.this can work effectively only in dry areas with low humidity because if the humidity levels are high the rate of evaporation and inter alia the rate of cooling will be very poor and ineffective.that is why in places like Delhi these are used only during March,April&May when the place reels in dry heat

Are you talking about "swamp coolers" that are used primarily in the SW US?
Swamp coolers are different than your normal air conditioners. They use water and add humidity to the air. If you used a traditional air conditioner, the air would be even more dry, and wouldn't really feel all that different. When you add humidity to the air, with the cooler temperature, it makes it feel much cooler.
Don't know for sure if that's what you are referring to, hope it helps.
